After successfully installing postgresql from source code, I got an error while installing Apache AGE. I have attached a screenshot of the error below. It would be great if someone can help out.Terminal view of command and error
I am searching online to find a solution but haven't been able to found yet.
From the image, it looks like you are using postgres 12.13.
For postgres 12, you should checkout to age for pg12 branch by doing git checkout release/PG12/1.1.1 and then make install.
I was also getting errors in a configuration which were resolved by using this command first.
sudo apt-get install build-essential libreadline-dev zlib1g-dev flex bison
Try this and this will solve your problem too
In addition to installing the essential libraries before the actual installation using:
sudo apt-get install build-essential libreadline-dev zlib1g-dev flex bison (Note: The above command is for Ubuntu only. If you are not on Ubuntu, See here)
It is also recommended to install the postgreSQL development files using:
sudo apt install postgresql-server-dev-xx
This is not the exact command to be typed in the terminal. Check out the link
here to see the exact compatible command to execute according to the version of Linux you are currently using.
While downloading any extension, I am having above error. I uninstalled the vs-code and installed it again, but the same problem occurs. How to solve this problem?
you can add extension via terminal. here are the steps to install the GCC compiler on Ubuntu:
sudo apt update
sudo apt install build-essential the command installs a bunch of new packages including gcc, g++ and make.
to check the version type the command gcc --version
Running as admin worked for me after experiencing the same issue.
I first installed Open Babel through brew. When I tried to run the command: "obabel -:"CC(=O)Cl" -opng -O mymol.png", I got this error message: " Open Babel Error in PNG Format
PNG2Format not found. Probably the Cairo library is not loaded." I then proceeded to use brew to uninstall Open Babel. Then, I installed Cairo with brew and then installed Open Babel with brew again. Still though, I try to create a PNG output and it gives me the same error message. I just do not know what's going on??
I’ve found that when using brew to install open-babel, I do not need to install Cairo in a separate step. The open-babel formula includes a '--with-cairo’ option that installs all the required dependencies, including Cairo.
Here is how I installed open-babel with Cairo support:
$ brew install --with-cairo open-babel
While am compile using swift build, am getting following error in my Ubuntu machine
$swift build
/home/xxxxxxxxx/Downloads/swift-DEVELOPMENT-SNAPSHOT-2016-02-25-a-ubuntu15.10/us
r/bin/swift-build: error while loading shared libraries: libicuuc.so.55: cannot
open shared object file: No such file or directory
How can i fix this issue?
Thanks.
You can manually download the good .dep
wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb
Then you run:
sudo dpkg -i libicu55_55.1-7_amd64.deb
If it miss some dependency:
sudo apt-get -f install
It has worked for me.
Your can find the other architecture on the debian package website :
https://packages.debian.org/sid/libicu55
p.s: I know this is on SID, but this is the only version that I found
*note...packages may have been removed
Your system lacks a critical component for building Swift, libicu-dev.
Install this:
sudo apt-get install libicu-dev
But that was for building Swift from source. You were talking about building with Swift, my apologies.
Unfortunately it seems it won't work either: Swift for Linux only officially runs on Ubuntu 15.10 and 14.04, and you tell me in the comments that you're running 15.04.
I know there's tutorials on the web on how to make it work on Mint and other distros... But the best would be, if possible, that you update your install of course.
I searched on the net and find a list in debian packages that shows the libicuuc.so.55 file.
apt-get install libicu55
Will resolve the issue.
hallow_me's link to download libicu55_55.1-7_amd64.deb doesn't work.
Here are the latest links https://packages.debian.org/stretch/amd64/libicu57/download
Like
wget http://ftp.us.debian.org/debian/pool/main/i/icu/libicu55_55.1-7_amd64.deb
Then follow hallow_me's instruction to install it.
Try the followings lines
echo "deb http://security.ubuntu.com/ubuntu xenial-security main" | sudo tee --append /etc/apt/sources.list
sudo apt-get update
sudo apt-get install libicu55
Is it possible to install psycopg2 into a virtualenv when PostgreSQL isn't installed on my development system—MacBook Pro with OS X 10.6?
When I run pip install psycopg2 from within my virtualenv, I received the error shown below.
I'm trying to connect to a legacy database on a server using Django, and I'd prefer not to install PostgreSQL on my development system if possible.
Why not install PostgreSQL?
I received an error when installing PostgreSQL using homebrew. I have Xcode4—and only Xcode4—installed on my MacBook Pro and am thinking it's related to missing gcc 4.0. However, this is a problem for another StackOverflow question.
Update 8:37 AM on April 12, 2011: I'd still like to know if this is possible without installing PostgreSQL on my MacBook Pro. However, I ran brew update and forced a reinstallation of ossp-uuid with brew install --force ossp-uuid and now brew install postgresql works. With PostgreSQL successfully installed, I was able to pip install psycopg2 from within my virtualenv.

Preliminary Research
Below are the articles I read as preliminary research:
Installing psycopg2 to use Django with PostgreSQL on OS X
Installing psycopg2 on OS X
Using psycopg2 with virtualenv on Ubuntu JauntyLucid
Postgres, psycopg2, virtualenv install hints
apt-get install libpq-dev
helped me on debian squeeze
From comments:
apt-get install python-dev-is-python3
psycopg depends on pg_config command, and if you don't have it, you can't install psycopg.
If system installation is a problem to you, why don't you try compiling PostgreSQL and including generated bin files in your $PATH? Like:
export PATH=/path/to/compiled/postgresql/bin:"$PATH"
pip install psycopg2
brew install postgresql
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
pip3 install psycopg2
apt-get install libpq-dev
helped me in debian squeeze too . After that do pip install psycopg2. I faced problem of pg_config not found problem when i was setting up my environment on heroku , now its working fine .
You need to install the python-dev package in order to make use of python extensions such as psycopg2. I don't know how to install packages in mac but I run the following commands to install a python package on my Ubuntu machine.
sudo apt-get install python-dev
Or
sudo apt-get install python3-dev
if you are using Python3.x.
Once the installation is finished run the following command within your virtual environment.
pip install psycopg2
You don't need the complete PostgreSQL installed: you only need the client side libraries.
I solved it in MAC OSX using :
$ wget https://ftp.postgresql.org/pub/source/v9.5.3/postgresql-9.5.3.tar.bz2
$ tar xfv postgresql-9.5.3.tar.bz2
$ cd postgresql-9.5.3
$ ./configure
$ make
$ cd src/bin/pg_config
$ export PATH=`pwd`:"$PATH"
$ pip install psycopg2
Use pip install psycopg2-binary, it worked for me when pip install psycopg2 wasn't working.
Using the method you described in your April 12th update, I was able to install PostgreSQL(+1). Note that I originally was running Python 2.7.1 (32bit) and homebrew threw several errors and warnings regarding using a 32bit version of Python. I have since switched the 64/32 bit version of 2.7.1 and it works like a champ.
Regarding the pyscopg2, I was able to install it into my virtual environment from source by editing setup.cfg. I set pg_config to correct path inside homebrew's Cellar (pg_config=/usr/local/Cellar/postgresql/9.0.4/bin/pg_config). After saving the changes, I ran python setup.py install with zero issues. It's worth noting that I did not set the Mac's default python setting to 32 bit. I used the new 64 bit from start to finish.
After looking over some of the documentation, I think if I added homebrew's postgresql path to the system path I could have used pip to install it.

Update 6-8-2011:
While porting a project written on OS X to Windows 7, I found out that I had to install PostgreSQL on Windows as well. This ended up creating another user on my start up screen and other things that I just didn't like. While doing some digging I found Windows drivers for PostgreSQL here. I have since uninstalled the full PostgreSQL and installed the ODBC drivers which, thus far, work great.
To address the original question, after doing a bit more digging I think I found the equivalent ODBC for OS X here. I have not had a chance to try them out, but the concept works very well on Windows 7. I will update this when I get a chance to try them out. Until then, I hope this helps.
All from the above doesn't work for me (OS Catalina 10.15.1)
There was a conflict with classical postgres and homebrew version.
Please delete homebrew version by command
$ brew uninstall postgresql
and then install it from the official website:
$ sudo mkdir -p /etc/paths.d && echo /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee /etc/paths.d/postgresapp
It is actual for a simple psycopg2 install or django-heroku package.
if you have recently updated python or changed default python (let's say from 3.6 to 3.8). The following code
sudo apt-get install python-dev OR sudo apt-get install python3-dev
will be installing/working for the previous python version.
so if you want this command to work for the recently updated/changed python version try mentioning that specific version like python3.8 in command like
sudo apt-get install python3.8-dev
try above with following
pip install wheel
export PATH=/path/to/compiled/postgresql/bin:"$PATH"
sudo apt-get install libpq-dev
sudo apt-get install python3.x-dev **Change x with your version, eg python3.8**
pip install psycopg2-binary
pip install psycopg2
As I never needed to install postgresql database on this server I installed the following libraries on Ubuntu 14_04 version before running pip install psycopg2 on the same server
apt-get install libpq-dev python-dev
and then executed pip install psycopg2 within virtual env.

I know you are asking for development environment but if you are deploying on server say, Heroku.
Just add below line in the requirements.txt of your project.
django-heroku==0.3.1
As this package itself will install the required packages like psycopg2 on server deployment.
Try to specify the version and it'll works, do it inside the venv
pip install psycopg2-binary==2.8.6
based on my experience, apt install libpq-dev then try to install psycopg2 inside venv will fix many issues, however for more information you can refer to this link:
