# virtualenv ## Custom Virtual Environment Location Pipenv automatically honors the `WORKON_HOME` environment variable, if it is set, so you can tell pipenv to store your virtual environments wherever you want, e.g.: export WORKON_HOME=~/.venvs In addition, you can also have Pipenv stick the virtualenv in `project/.venv` by setting the `PIPENV_VENV_IN_PROJECT` environment variable. ## Virtual Environment Name The virtualenv name created by Pipenv may be different from what you were expecting. Dangerous characters (i.e. `` $!*@"` ``, as well as space, line feed, carriage return, and tab) are converted to underscores. Additionally, the full path to the current folder is encoded into a "slug value" and appended to ensure the virtualenv name is unique. Pipenv supports a arbitrary custom name for the virtual environment set at `PIPENV_CUSTOM_VENV_NAME`. The logical place to specify this would be in a user's `.env` file in the root of the project, which gets loaded by pipenv when it is invoked.
