How to set the full name of the virtualenv created

When using inside my project directory PROJECTDIR

pipenv install

pipenv creates a virtualenv named "PROJECTDIR-<someid>". How can I specify this full name myself, say to call the virtualenv just "PROJECTDIR"?

And how can I tell pipenv to use an existing virtualenv for this directory and just add the new packages from the requirements.txt?

This has been discussed multiple times in the past. You can search the issue tracker for similar entries. To sum things, it is not possible (at this time; can’t say for the future) to specify the name of the virtualenv, since Pipenv relies on this information to associate it to your project. The alternative is to set environment variable PIPENV_VENV_IN_PROJECT to tell Pipenv to look for the a directory named .venv inside your project (the same level as Pipfile).

To import dependencies from requirements.txt, use pipenv install -r. This converts the requirements file to a Pipfile, and use it to create the environment. There is not way to specify an existing virtualenv (unless you name it exactly the same as Pipenv would).

Most of the above is mentioned in detail in the documentation. Please check out relevant sections for more information.

One of my main issues with not being able to choose a name for the virtual environment is that it doesn’t take into account varying folder structures. I usually follow a common convention and like to nest my source code inside a /src directory of my main project folder. In the /Users/NAME/.local/share/virtualenvs directory every virtual env looks like:

src-Q4dXJo6L
src-ha_K95Ys
...

This makes it a little harder to distinguish between them.

This is also problematic when you have a frontend and backend in your repo, each with separate Pipenv files for separate dependencies. Again, I’d ideally like to name the project PROJECT-frontend and PROJECT-backend. With the hash suffix on both of those.

It would be nice to have a little control on the virtual environment naming.
