libXp.so library missing on Ubuntu 16.04 - matlab

I'm trying to install Matlab on my Ubuntu 16.04 (64 bit), and it says 'the X11 library libXp.so does not exist. Matlab won't run on this machine until the library is installed'. I followed some other forums about this problem, and the instruction was to install libxp6 (sudo apt-get install libxp6). I did so, but the problem still persists. I searched for the libxp.so library on my system but couldn't find it.
When tryng to run Matlab from the bin folder using ./matlab, it says error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory
How do I install the libxp.so on ubuntu 16.04? Do I need to run any specific package for it? If libXp.so is installed, then how do I locate the .so library? Please help.

On my Ubuntu 16.04 machine I did dpkg -S /usr/lib/x86_64-linux-gnu/libXp.so and found out that this file is provided by the libxp-dev package.
So sudo apt-get install libxp-dev is likely to fix your problem.

Can't install powershell in Parallels Kali Linux Virtual Machine

I've been trying to install Powershell for a few hours now. I run this under root:
apt update && apt -y install powershell
This is what I end up getting after it runs through and seemingly downloads
Package powershell is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'powershell' has no installation candidate
When I try to run this same command outside of root using sudo, I get the following:
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
I have updated everything and tried a few different ways. I even downloaded a completely new Virtual Machine in Parallels to see if restarting would help out. I still run into the same problems. This is a Kali Linux VM on Parallels MacOS M1. Not sure if that matters or not. I think Parallels itself may possibly be using an apt process in the background, but when I do:
sudo killall apt apt-get
I end up getting
apt: no process found
apt-get: no process found
I've been trying everything. I'm on a new Mac so I don't have too many VM options. If someone could figure this out in Parallels, it would be a great help.
I've tried a lot. In the description above.
To install PowerShell in Kali Linux open the terminal and type:
sudo apt update
sudo apt install -y snapd # install daemon and tooling that enable snap packages
sudo systemctl enable --now snapd apparmor
Log out and back in again, and run the following command to install the powershell snap package.
sudo snap install powershell --classic

Trying to import docx in Python

Fair Warning: I am extremely new to python, so please excuse any dumb mistakes I make =)
I would like to be able to open/close/manipulate/read Word documents (docx files) on my Mac using Python. The python-docx module looked really useful, so I have been trying to install it on my system, to no avail.
Here's what I've done so far:
Checked that I do indeed have python installed using the python --version command in terminal. I have version 3.7.0, so all good there.
Checked that I do indeed have pip installed - I was able to use pip install and pip uninstall commands, so all good. I also upgraded my pip version using pip install --upgrade pip to pip-19.1.1
Following the online documentation (see here), I tried pip install python-docx. This seemed to work just fine, and after the progress bar loaded all the way I saw:
Successfully built python-docx
twisted 18.7.0 requires PyHamcrest>=1.9.0, which is not installed.
Installing collected packages: python-docx
Successfully installed python-docx-0.8.10
I wasn't completely sure what pyhamcrest was, but I installed it anyway just to be safe using pip install pyhamcrest
As other sites suggested, I also tried to install Pillow, lxml, and python-dateutil using their respective install commands, and in each case saw the Requirement already satisfied: message, with an anaconda path listed.
Frustrated, I also tried easy_install python-docx, the manual version, and even pip install docx . In all cases, when I run IDLE and type from docx import Document or just import docx, I get the following message in the shell:
`Traceback (most recent call last):`
`File "/Users/[my_name]/Desktop/Medical.py", line 3, in <module> `
`import docx`
`ModuleNotFoundError: No module named 'docx'`
Could anyone help point me in the right direction? Thank you very much.
The Anaconda Python distribution has its own system of installation of packages.
After the installation of Anaconda, the variable $PATH has been modified so that anaconda python was the first, and OsX's python in the last position.
If you type "python" in a shell will execute the anaconda python, instead of the standard OsX python (which is 2.7, not 3.x).
Following the instructions of the package python-docx, you have installed it using pip, which is the default method for installing packages, but this method is not valid for Anaconda Python. So, you finished installing python-docx for the python 2.7 of OsX.
To install packages for anaconda, you must run the command
conda install <package>
The python-docx module for anaconda can be found in a separated repository called conda-forge; typing the command
conda install -c conda-forge python-docx
you will install the package and the requested dependencies.
Other useful commands are:
anaconda-navigator for exploring the Anaconda system
anaconda-project for managing projects with anaconda
idle3 for Anaconda Python shell.
Before start coding, run anaconda-navigator and take a look at the 'Learning' section.
For a better experience, I suggest PyCharm IDE for Anaconda from JetBrains.

I want to install wxpython_phoenix on raspberrypi3

I am trying to run the gui program on raspberrypi3 using python3.6.1 and the wx module
I'm looking for wxpython_phoenix for the raspbian operating system, but not at https://wxpython.org/Phoenix/snapshot-builds/linux/. Do you mind installing debian8?
I am trying to install this by referring to the manual. sudo pip3 install --upgrade --pre -f https://wxpython.org/Phoenix/snapshotbuilds/linux/gtk3/debian-8/wxPython-4.0.0a3.dev3059+4a5c5d9-cp34-cp34m-linux_x86_64.whl
But is not it because it is different from the Linux operating system?
wxPython 4 is out now, which is based on Phoenix. You can just install it like this:
pip install wxPython
Note that you may need to install webkit BEFORE you install wxPython as I have had mine fail when webkit isn't there. The creators of wxPython are working on an update that will ignore this sort of thing soon.

CakePHP3 - Apache/Server Error 500 - MAMP [duplicate]

Using the CakePHP docs, I am trying to install 3.0-beta2 using composer but I got this error:
cakephp/cakephp 3.0.x-dev requires ext-intl * -> the requested PHP extension intl is missing from your system
However, I know for sure that intl is installed (it shows on phpinfo). I'm using PHP 5.4.33/Apache 2.4.10.1
I faced the same problem today. You need to enable the intl PHP extension in your PHP configuration (.ini).
Solution Xampp (Windows)
Open /xampp/php/php.ini
Change ;extension=php_intl.dll to extension=php_intl.dll (remove the semicolon)
Copy all the /xampp/php/ic*.dll files to /xampp/apache/bin
Restart apache in the Xampp control panel
Solution Linux (thanks to Annamalai Somasundaram)
Install the php5-intl extension sudo apt-get install php5-intl
1.1. Alternatively use sudo yum install php5-intl if you are on CentOS or Fedora.
Restart apache sudo service apache2 restart
Solution Mac/OSX (homebrew) (thanks to deizel)
Install the php5-intl extension brew install php56-intl
If you get No available formula for php56-intl follow these instructions.
Restart apache sudo apachectl restart
Eventually you can run composer install to check if it's working. It will give an error if it's not.
I faced the same issue in ubuntu 12.04
Installed: sudo apt-get install php5-intl
Restarted the Apache: sudo service apache2 restart
OS X Homebrew (May 2015):
The intl extension has been removed from the main php5x formulas, so you no longer compile with the --enable-intl flag.
If you can't find the new package:
$ brew install php56-intl
Error: No available formula for php56-intl
Follow these instructions: https://github.com/Homebrew/homebrew-php/issues/1701
$ brew install php56-intl
==> Installing php56-intl from homebrew/homebrew-php
When using MAMP
1 Go to terminal
vim ~/.bash_profile
i
export PATH=/Applications/MAMP/bin/php/php5.6.2/bin:$PATH
Change php5.6.2 to the php version you use with MAMP
Hit ESC,
Type :wq,
hit Enter
source ~/.bash_profile
which php
2 Install Mac Ports
https://www.macports.org/install.php
sudo port install php5-intl OR sudo port install php53-intl
cp /opt/local/lib/php/extensions/no-debug-non-zts-20090626/intl.so /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/
{take a good look at the folder names that u use the right ones}
3 Add extension
Now, add the extension to your php.ini file:
extension=intl.so
Usefull Link:
https://gist.github.com/irazasyed/5987693
The error message clearly states what the problem is. You need the intl extension installed.
Step 1: install PHP intl you comfortable version
$sudo apt-get install php-intl
step 2:
For XAMPP Server intl extension is already installed, you need to enable this extension to uncomment below the line in your php.ini file. Php.ini file is located at c:\xampp\php\php.ini or where you have installed XAMPP.
Before uncomment:
;extension=php_intl.dll ;extension=php_mbstring.dll
After uncommenting:
extension=php_intl.dll extension=php_mbstring.dll
Short answer: activate intl extension in php_cli.ini. Thanks to #ndm for his input.
If you are using latest version Ubuntu 16.04 or later just do
sudo apt-get install php-intl
Then restart your apache
sudo service apache2 restart
In my case I was not actually trying to run cakephp locally, I was just trying to get it to auto update locally using composer (because I am playing with writing plugins that you install with composer). Since I don't actually even run it locally I could simply ignore requirements by adding the --ignore-platform-reqs flag.
php composer.phar update --ignore-platform-reqs
In my case, my running php version is 7.1.x on mac OSX .
I installed intl command using brew install php71-intl.
Placing extension=intl.so inside php.ini was no effect at all. Finally i looked for extension installed directory and there i saw intl.so and placed that path (extension=/usr/local/Cellar/php71-intl/7.1.11_20/intl.so) to my php.ini file and it solved my problem.
In my case (xampp PHP 8.0)
Find ;extension=intl in /xampp/php/php.ini
Remove ; and Restart Apache
MAKE this
In XAMPP, intl extension is included but you have to uncomment extension=php_intl.dll in php.ini and restart the server through the XAMPP Control Panel.
In WAMP, the intl extension is “activated” by default but not working. To make it work you have to go to php folder (by default) C:\wamp\bin\php\php{version}, copy all the files that looks like icu*.dll and paste them into the apache bin directory C:\wamp\bin\apache\apache{version}\bin. Then restart all services and it should be OK.
if you use XAMPP do this
1. turn off XAMPP
2. Modifed the php.ini is located in c/:xampp/php/php.ini
3. intl extension is included but you have to uncomment extension=php_intl.dll in php.ini and restart the server through the XAMPP Control Panel.
For Ubuntu terminal:
Please follow the steps:
Step-1:
cd ~
Step -2: Run the following commands
sudo apt-get install php5-intl
Step -3: You then need to restart Apache
sudo service apache2 restart
For Windows(XAMPP) :
Find the Php.ini file:
/xampp/php/php.ini
Update the php.ini file with remove (;) semi colon like mentioned below:
;extension=php_intl.dll to extension=php_intl.dll
and save the php.ini file.
After that you need to
Restart the xampp using xampp control.
Intl Means :Internationalization extension which enables programmers to perform UCA-conformant collation and number,currency,date,time formatting in PHP scripts.
To enable PHP Intl with PECL can be used.
pecl install intl
On a plain RHEL/CentOS/Fedora, PHP Intl can be install using yum
yum install php-intl
On Ubuntu, PHP Intl can be install using apt-get
apt-get install php5-intl
Restart Apache service for the changes to take effect.
That's it
For those who get Package not found error try sudo apt-get install php7-intl then run composer install in your project directory.
I had the same problem in windows
The error was that I had installed several versions of PHP and the Environment Variables were routing to wrong Path of php see image example
I'm using Mac OS High Sierra and none of these worked for me. But after searching a lot I found one that worked!
This may seem trivial, but in fact about 2 months ago some clever guys made changes in brew repository, so doing just: brew install php71-intl will show you error with message that such recipe doesn’t exists.
Fortunately, there is. There is temporary fix in another brew repo, so all you have to do is:
brew tap kyslik/homebrew-php
brew install kyslik/php/php71-intl
SOURCE: http://blastar.biz/2018/04/14/how-to-enable-php-intl-extension-for-php-7-1-using-xampp-on-macos-high-sierra/
I use Linux Ubuntu 20, you can try this:
Check php installed modules:
php -m | grep intl
If there are no result(s) from this command, you should just go ahead and install the module:
sudo apt-get install php7.4-intl
you will need to change *php7.4 to your desired php version.
you should restart apache when you're done:
sudo service apache2 restart

PyEphem running error on Ubuntu

I have read previous posts on installation issues. Nothing seems to work.
I have Ubuntu 14.04LTS, 32 bit, Anaconda python ver 2.7.
I installed pyephem using sudo pip install pyephem [after checking I have python-dev, and latest pip] Installation said it was successful.
When I run Python 2.7 and try to import ephem, it says Import error:
No Module named _libastro.
Any help will be appreciated.
If you are using Anaconda and have activated your conda environment, you should not need to use sudo — that might aim the install at your system Python, the one governed by the root account and by sudo, instead. You could try activating your conda environment and then just doing conda install ephem because it comes built in to conda, you do not need pip plus a compiler to try installing it!
