Direnv

Installing direnv

Of course you can use pixi to install direnv globally. We recommend to run

pixi global install direnv

to install the latest version of direnv on your computer.

You can use pixi in combination with direnv to automatically activate environments on entering the corresponding directory. Enter the following into your .envrc file:

.envrc
watch_file pixi.lock # (1)!
eval "$(pixi shell-hook)" # (2)!
  1. This ensures that every time your pixi.lock changes, direnv invokes the shell-hook again.
  2. This installs if needed, and activates the environment. direnv ensures that the environment is deactivated when you leave the directory.
