Description

Install an environment, both updating the lockfile and installing the environment.

This command installs an environment, if the lockfile is not up-to-date it will be updated.

pixi install only installs one environment at a time, if you have multiple environments you can select the right one with the --environment flag. If you don't provide an environment, the default environment will be installed.

If you want to install all environments, you can use the --all flag.

Running pixi install is not required before running other commands like pixi run or pixi shell. These commands will automatically install the environment if it is not already installed.

You can use pixi reinstall to reinstall all environments, one environment or just some packages of an environment.
