[SOLVED] ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/var/project_env/bin/pip'

Issue

First of all I am pretty new to setting up virtual env so I can run a Python rest api on it . :)

I installed the virtual env. in the /var folder of my Ubuntu server with sudo python3 -m venv project_env.

After activating the environment I tried to install Flask with following command: (project_env) mStege@homeserver:/var$ pip install Flask

I get this error:

ERROR: Could not install packages due to an EnvironmentError: 
[Errno 13] Permission denied: '/var/project_env/lib/python3.8/site-packages/itsdangerous-2.0.1.dist-info' Consider using the `--user` option or check the permissions.

After some research I tried following command to install Flask: pip3 install Flask --user Which give me this error:

ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

Has it something to do where I installed the virtual enviroment? I didn't put it in my homedir because there is a project-related website in the var folder and I want everything in one place. Also, there will be some other dudes I will be working with and I thought that it is quite suboptimal when they have to go through my home folder.

Solution

Don't create your virtual environment (venv) in /var.

My advice:

• Create your virtual environment alongside your source code, if you're using pip
• If you're using pipenv, let pipenv choose where to create the venv

Each one of your colleagues should have their own venv. You can syncronize your environments by using a requirements.txt (or a Pipfile) to specify which packages and versions are needed.
