I'm trying to use python3.6 -m venv test directly in PythonAnywhere to create a virtualenv. I wanted to use this method as I believe it is more portable to other environments where virtualenvwrapper might not be set up.
When I run the command (in a PA environment that has been upgraded to use Python 3.6) I get the following error.
12:34 ~ $ python3.6 -m venv test
Error: Command '['/home/dpottsagilisys/test/bin/python3.6', '-Im', 'ensurepip',
'--upgrade', '--default-pip']' returned non-zero exit status 1.
PythonAnywhere dev here: this appears to be a bug in Ubuntu 14.04 (and apparently 15.04), which we were based on when this question was originally asked.
This Ask Ubuntu question has various suggestions; here's one that I've made 100% certain works on PythonAnywhere:
python3.6 -m venv --without-pip test
source test/bin/activate
curl https://bootstrap.pypa.io/get-pip.py | python
deactivate
source test/bin/activate
[Update 28 June 2018: Switching to a 16.04 image is, coincidentally, what we're working on right now.]
[Update 30 September 2018: the 16.04 image is now live for new PythonAnywhere accounts]
Not having the package python3.6-venv causes this issue. Installing with:
sudo apt-get install python3.6-venv should resolve.

I am using Ubuntu 14.04 LTS. After updating VSCode to v.1.53.0 I am getting following message on opening VSCode:
/usr/share/code/bin/../code: /usr/lib/x86_64-linux-gnu/libxkbcommon.so.0: no version information available (required by /usr/share/code/bin/../code)
On giving command code --verbose I get following logs: logs
I cannot update current Ubuntu version due to limited admin rights.
If you run code --verbose you will see real problem:
[main 2021-04-16T11:44:45.671Z] Main->SharedProcess#connect
/usr/share/code/code --verbose --no-sandbox: relocation error: /usr/share/code/resources/app/node_modules.asar.unpacked/spdlog/build/Release/spdlog.node: symbol _ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE7compareEPKc, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference
It can't find symbol basic_string::compare
echo _ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE7compareEPKc | demangle
So to run visual studio code on Ubuntu 14.04 LTS
You just need to copy libstdc++.so.6.0.28 and libstdc++.so.6
to /usr/share/code from ubuntu 20.04 LTS
You can get libstdc++.so.6.0.28 (md5=0e7d34a60136c0cd150917ed099980f2) for example from this deb file
Here simple script to do it for you
#!/bin/sh
wget https://mirrors.wikimedia.org/ubuntu/ubuntu/pool/main/g/gcc-10/libstdc%2B%2B6_10.2.0-5ubuntu1~20.04_amd64.deb
dpkg-deb -R libstdc++6_10.2.0-5ubuntu1~20.04_amd64.deb .
sudo cp -P usr/lib/x86_64-linux-gnu/* /usr/share/code/
file version changed in wikimedia.org so new script:
#!/bin/sh
wget https://mirrors.wikimedia.org/ubuntu/ubuntu/pool/main/g/gcc-10/libstdc%2B%2B6_10.3.0-1ubuntu1~20.04_amd64.deb --no-check-certificate
dpkg-deb -R libstdc++6_10.3.0-1ubuntu1~20.04_amd64.deb .
sudo cp -P usr/lib/x86_64-linux-gnu/* /usr/share/code/
md5sum of new libstdc++.so.6.0.28 604ec2999aeb3aadd0e96103fd4b5e5d
Then just type code
ps: very good font for vscode JetBrains Mono
I downgraded my VSCode to lower version. Apparently you can access previous versions of VSCode from it's website but the link's font was too big form me to see.
Still if someone does come across any other alternative please share.
Leaving this here for others.
I have two servers that are running CentOS 7.8 with all the latest patches as of the date of this post. On one server I can create a venv, and on the other I get an error. Here is the command used to create the venv:
python3.6 -m venv venv
The error is:
Error: Command '['/root/venv/bin/python3.6', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
So it seems there is a problem after the venv is created. In fact, it makes the links to the python interpreters in venv/bin, but the lib64/python3.6 and lib/python3.6 directories that are created have only empty site-packages in them. I get the problem whether running the command with root privileges (as above) or as a non-privileged user. On the other system, which is not quite the same hardware but very similar, I get no errors.
I have tried a bunch of things including completely uninstalling all the python3 rpms and reinstalling them on both systems. The python3 modules installed are:
python3, python3-devel, python3-libs, python3-other-rpm-macros, python3-pip, python3-rpm-generators, python3-setuptools, python3-tkinter, python3-wheel. All these are installed using the centos repos.
I have searched the internet and one thing that works is to use --no-pip. However, not surprisingly, if I do that I get a venv with no pip, which does not work very well. The version of pip that is installed with the rpm is version 9.0.3. However, I have tried upgrading pip:
python3.6 -m pip install --upgrade pip
This installs pip 20.1. Interestingly, it is installed in /usr/local/lib/python/site-packages. In any event, it doesn't change anything and I get essentially the same error message.
I have even gone as far as rsyncing the /usr/lib/python3.6 and /usr/lib64/python3.6 (using -avu --delete) on the two servers so that they are identical. All to no avail. I am at a loss to know what to do.
I can of course hack things to make them work, but since I am using this to automatically build test environments I really need to get it working automatically. Suggestions would be greatly appreciated.
I've had the same issue on CentOS Linux release 7.9.2009 (Core) and solved it by installing the following system packages:
yum install python36-devel
yum install python36-setuptools
yum install python36-virtualenv
python3.6 -m pip install --upgrade pip
Used virtualenv to install the venv into the project-root:
python3 -m virtualenv venv-dev
After sourcing the venv everything looks good and I could install the needed requirements:
. ./venv-dev/bin/activate
python3 --version
Python 3.6.8
pip3 --version
pip 21.1.1 from /project/root/dir/venv-dev/lib/python3.6/site-packages/pip (python 3.6)
pip3 install -r requirements/dev.txt
Successfully installed ...
I'm working on an Ubuntu 16 server and I can't seem to get the mongodb driver for php 7 to work. I installed it successfully on my xampp on my windows machine but Ubuntu and php7 seemingly have vast differences.
I did try to install it via pecl install mongodb and used composer to put in the dependencies but it still does not work. I'm using the same php file from my windows Xampp and when I access the page it throws a 500 status code.
Could someone provide a definitive walkthrough on how to install this driver and maybe also how to revert any changes I made using composer and pecl?
Cool even I tried with pecl but didn't work as expected. It work with pecl7 Also, I received this warning along with error, WARNING: "pecl/mongo" is deprecated in favor of "channel:///mongodb" pecl/mongo requires PHP (version >= 5.3.0, version <= 5.99.99), installed version is 7.1.8. Also, got 500 Internal server error.
Before that MongoDB php7 driver, I needed the memcache and getting phphize error that I solved using this repo. Then finally I use this low level PHP driver for MongoDB.
$ git clone https://github.com/mongodb/mongo-php-driver.git
$ cd mongo-php-driver
$ git submodule sync && git submodule update --init
$ /usr/bin/phpize
$ ./configure
$ make all -j 5
$ sudo make install
You can confirm from the output that mongodb.so driver is installed.
;;;;;;;;;;;;;;;;;;;
; Module Settings ;
;;;;;;;;;;;;;;;;;;;
extension=mongodb.so
Then only step remaining is make it available in your respective path. You can check your extensions_dir in php.ini with the following command,
$ php -i | grep extension_dir
extension_dir => /usr/lib64/php/7.0/modules => /usr/lib64/php/7.0/modules
And, I can verify that mongodb.so is present into the above directory. Then reload the composer and you are good to go ! Hope this helps as it work for me.
I am using Linux Mint 18. I installed Python 3.5 and 3.6 using apt-get in the terminal. I can open IDLE of Python 2.7 and 3.5 using commands idle and idle3 respectively. How can I access IDLE that comes with Python 3.6?
Try the command idle3.6. python3 and idle3 are still associated with your system Python, which is 3.5.
Simply typing in idle3.6 should work just like carusot42 mentioned. If it doesn't work, perhaps you might want to see if everything else is installed correctly. Here are the steps I followed which worked perfectly fine for me. I am also running Linux Mint 18. The steps that I followed were:
Installed the prerequisites of Python. Do that by typing in the following commands -
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
Download Python using the following command and extract it (use your desired location) -
cd /usr/src
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
sudo tar xzf Python-3.6.0.tgz
The next step is to compile Python source. To do that type in the commands below-
cd Python-3.6.1
./configure
sudo make altinstall
make altinstall is used to prevent replacing the default Python binary
file /usr/bin/python
You should be good to go. You check your Python version by typing python3.6 -V in the terminal.
Once you do that, type in idle3.6 and then Python 3.6.1 shell should open for you.
The Software Manager in Linux Mint lists the Python Packages and IDLE Packages
separately. After you install Python, go look up the associated IDLE package in the Software Manager and install it. Reboot and it should work fine. It worked for me.
I'm trying to install NetBeans on Linux Mint, and I'm getting the following error every time I run the installation script:
Configuring the installer...
Searching for JVM on the system...
Extracting installation data...
Running the installer wizard...
Can`t initialize UI
Running in headless mode
What should I do to get it working?
In case anyone has this problem in the future, Netbeans doesn't like OpenJDK 6 but -- fortunately -- it works fine with OpenJDK 7 (as expected as for Java 7 OpenJDK is the reference implementation). Just make sure you remove any Java 6 packages before installation attempts. On Ubuntu and Mint one can do:
sudo apt-get purge ^openjdk-6-*
sudo apt-get install openjdk-7-jdk
It should work afterwards.
Looks like Netbeans does not work properly with Openjdk. This is what I did (in Linux Mint 12):
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
Then you will be able to run the .sh installer as usual.
I hit this same issue on Kubuntu 12.04 LTS but needed Sun JDK 6 for a project I'm maintaining. I stumbled upon Martin Wimpress' OAB-Java script (by way of help.ubuntu.com) which creates and installs a local apt repository for Sun JDK 6. You can find the latest instructions on Martin's github site which run as follows:
cd ~/
wget https://github.com/flexiondotorg/oab-java6/raw/0.2.7/oab-java.sh \
-O oab-java.sh
chmod +x oab-java.sh
sudo ./oab-java.sh
If you want to see what this script is doing while it is running then execute the following from another shell:
tail -f ./oab-java.sh.log
Alternatively, you can clone the OAB-Java repo and kick of the script from within it:
git clone git://github.com/flexiondotorg/oab-java6.git
cd oab-java6
sudo ./oab-java.sh
Either way, once that is in place follow Jose's instructions to remove openjdk and install sun jdk:
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
One final note, the script accepts a -7 argument which will create and install a local apt repository for Oracle JDK 7 should you want to go that route.
I was able to get it to work by getting into the target system using ssh -X, then making sure DISPLAY was exported. That handles the X server issues.
Change the priority of the Oracle Java executables:
export PATH=/usr/java/latest/bin:$PATH
Run the installer:
./netbeans-8.1-linux.sh
What worked for me was installing default java environment from the terminal:
sudo apt-get install default-jre
The installation was a success - under "user".
The installation failed - under "su" (under Red Hat equivalent of "sudo"). With
Can`t initialize UI
Running in headless mode
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
For me.
