Installing older modular/mojo versions via pixi

Installation & Packaging
1

Currently the newest stable release version is 25.5 and installing that via pixi works.

$ pixi add "mojo=25.5"
✔ Added mojo=25.5

But trying to add 25.4 fails.

$ pixi add "mojo=25.4"
Error:   × failed to solve the conda requirements of 'default' 'linux-64'
  ╰─▶ Cannot solve the request because of: No candidates were found for mojo 25.4.*.

I use pixi 0.46.0.

You’ll need to use max for versions older than 25.5. We only first created a dedicated mojo Conda package in 25.5, so older versions of Mojo were only available as part of the greater max package.
