pipenv : how to force virtualenv directory?

Actually, pipenv will install the virtualenv with a path like this :

$WORKON_HOME/<base_dir>-<hash>

Is it possible to have exactly the path I want, that is without the base_dir and the hash, for exemple : 

/home/user/myapp_venv

There's an undocumented feature in pipenv: if you create a file named .venv in the project root with a path in it, pipenv will use that instead of an autogenerated path.

This, however, is more fit for cases when you already have an established set of environments that you wish to reuse. Otherwise, placing environments in arbitrary places is prone to create a mess eventually. pipenv relieves you from this task specifically to keep them all in one predictable place and eliminate accidental collisions from human error.

Creating a directory .venv in the project then try to initiate with pipenv install <some package> did not work for me at the first in my mac, it was always creating virtual environment somewhere else. Though later I figure it out the reason. The hack is, first cd to the project folder cd /Home/.../MyProject then create a empty Pipfile touch Pipfile the create a directory mkdir .venv should work. Now you can run pipenv install and .venv folder will be used.

Now the elaboration is given form the source code. When the pipenv try to create create a virtual env it looks to the directory dot_venv = os.path.join(self.project_directory, ".venv") (taken from source code) and thats how the self.project_directory looks like:

@property
    def project_directory(self):
        # type: () -> str
        return os.path.abspath(os.path.join(self.pipfile_location, os.pardir))

So that function looks for the pipfile location to create the path it will create the virtual environment. So if you create the empty Pipfile before hand it is confirmed that it will find that file and then find the .venv directory and create the path all together.

Apart from using a custom location, you can also install the virtualenv in your project's directory. Just add the following line in your .bashrc/.zshrc file:

export PIPENV_VENV_IN_PROJECT=1

Just wanted to let others know that there is another approach available too.

Should you keep the virtualenv inside or outside the project's directory is an opinionated question afterall.

There is an undocumented feature of pipenv, it could locate virtualenv path from VIRTUAL_ENV environment variable, but you need to create virtualenv manually:

virtualenv /home/user/myapp_venv
VIRTUAL_ENV=/home/user/myapp_venv pipenv install
