Activate/deactivate conda virtualenvs on entering/leaving directories

Question

pyenv-virtualenv offers a nice way of activating the environment on the very instant of entering or leaving the directory which contains a .python-version text file

Answer 1

As mentioned in my comment, this is currently not supported. There is however an open issue on conda's GitHub asking for this feature.

In the meantime you could use autoenv, a small tool that'll automatically run the code in a .env file when entering a directory and that in a .env.leave when leaving the directory (supports bash/zsh and a couple others).

A simple example taken from their readme which illustrates the feature quite nicely:

$ echo "echo 'whoa'" > project/.env
$ cd project
whoa

To load a conda environment your .env would simply look like this:

conda activate 

Note 1: Check out the Configuration section of their GitHub readme before you start using it.

Note 2: The author of autoenv actually suggests trying direnv instead. However I've never used it, so I can't comment on it.

From autoenv's readme:

you should probably use direnv instead. Simply put, it is higher quality software. But, autoenv is still great, too. Maybe try both? :)
