Install Mojo

Version: Nightly

Mojo installs exactly like a Python or Conda package on macOS and Linux (see the system requirements).

uv

1. If needed, install uv:

   curl -LsSf https://astral.sh/uv/install.sh | sh

2. Install Mojo:

   uv pip install mojo \
     --index https://whl.modular.com/nightly/simple/ \
     --prerelease allow

   Or create a project and install Mojo:

   uv init hello-world
   cd hello-world
   uv add mojo \
       --index https://whl.modular.com/nightly/simple/ \
       --prerelease allow

pixi

1. If needed, install pixi:

   curl -fsSL https://pixi.sh/install.sh | sh

2. Create a project and install Mojo:

   pixi init hello-world \
     -c https://conda.modular.com/max-nightly/ -c conda-forge
   cd hello-world
   pixi add mojo

These commands install the nightly build, which isn't complete and might have new bugs. If you instead want the stable build, switch to the stable docs.
