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
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.
Output Collecting psycopg2 Using cached psycopg2-2.6.1.tar.gz Building wheels for collected packages: psycopg2 Running setup.py bdist_wheel for psycopg2 Stored in directory: /root/.cache/pip/wheels/e2/9a/5e/7b620848bbc7cfb9084aafea077be11618c2b5067bd532f329 Successfully built psycopg2 Installing collected packages: psycopg2 Successfully installed psycopg2-2.6.1
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
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.
Use pip install psycopg2-binary
, it worked for me when pip install psycopg2
wasn't working.
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.
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
