Mise¶
Mise is a tool for managing Software environments. It allows you to easily install and switch own versions of Python, Node.js, Ruby (Replacement for RVM), Rust and Go (Golang).
Python¶
To install own version of Python using Mise, follow these steps:
Install the Python interpreter¶
Mise is globally installed and ready to use. You can install a specific Python version by running the following command:
$ TMPDIR=~/.tmp mise install python@3.13
This will download and install Python version 3.13. You can check installed Python versions by running:
$ mise list
Activate new Python¶
Add ~/.local/share/mise/installs/python/X.Y.Z/bin to $PATH by executing:
$ eval "$(mise env -s bash python@3.13)"
or add the new $PATH to ~/.bash_profile to apply the environment automatically during every login:
$ mise env -s bash python@3.13 >> ~/.bash_profile
Install ipython (optional)¶
After installing Python, you may want to install IPython, an enhanced interactive Python shell:
$ mise exec python@3.13 -- pip install ipython
Once installed, you can start an interactive IPython session by running:
$ mise exec python@3.13 -- ipython
Node.js¶
To install Node.js using Mise, follow these steps:
Install the Node.js runtime¶
Mise is globally installed and ready to use. You can install a specific Node.js version by running the following command:
$ TMPDIR=~/.tmp mise install node@22
This will download and install Node.js version 22. You can check installed Node.js versions by running:
$ mise list
Activate new Node.js¶
Add ~/.local/share/mise/installs/node/X.Y.Z/bin to $PATH by executing:
$ eval "$(mise env -s bash node@22)"
or add the new $PATH to ~/.bash_profile to apply the environment automatically during every login:
$ mise env -s bash node@22 >> ~/.bash_profile
Install Yarn (optional)¶
After installing Node.js, you may want to install Yarn, an alternative package manager to npm:
$ mise exec node@22 -- corepack enable
$ mise exec node@22 -- npm install -g yarn
To verify the installation:
$ mise exec node@22 -- yarn --version
Ruby¶
To install Ruby using Mise, follow these steps:
Install the Ruby interpreter¶
Mise is globally installed and ready to use, you can install a specific Ruby version by running the following command:
$ TMPDIR=~/.tmp mise install ruby@3.3
This will download and install Ruby version 3.3. You can check installed Ruby versions by running:
$ mise list
Activate new Ruby¶
Add ~/.local/share/mise/installs/ruby/X.Y.Z/bin to $PATH by executing:
$ eval "$(mise env -s bash ruby@3.3)"
or add new $PATH to ~/.bash_profile file to apply enviroment automatically during every login:
$ mise env -s bash ruby@3.3 >> .~/.bash_profile
Install Bundler (optional)¶
After installing Ruby, you may want to install bundler to manage your project's gems:
$ mise exec ruby@3.3 -- gem install bundler
Rust¶
To install your own version of Rust using Mise, follow these steps:
Install the Rust toolchain¶
Mise is globally installed and ready to use. You can install a specific Rust version by running the following command:
$ TMPDIR=~/.tmp mise install rust@1.76
This will download and install Rust version 1.76. You can check installed Rust versions by running:
$ mise list
Activate new Rust¶
Add ~/.local/share/mise/installs/rust/X.Y.Z/bin to $PATH by executing:
$ eval "$(mise env -s bash rust@1.76)"
or add the new $PATH to ~/.bash_profile to apply the environment automatically during every login:
$ mise env -s bash rust@1.76 >> ~/.bash_profile
Install Cargo Edit (optional)¶
After installing Rust, you may want to install cargo-edit, which adds useful commands for managing dependencies:
$ mise exec rust@1.76 -- cargo install cargo-edit
With cargo-edit, you can:
- Add a dependency (e.g.
serde):$ mise exec rust@1.76 -- cargo add serde - Remove a dependency (e.g.
serde):$ mise exec rust@1.76 -- cargo rm serde - Upgrade dependencies:
$ mise exec rust@1.76 -- cargo upgrade
Golang¶
To install your own version of Go (Golang) using Mise, follow these steps:
Install the Go runtime¶
Mise is globally installed and ready to use. You can install a specific Go version by running the following command:
$ TMPDIR=~/.tmp mise install go@1.24
This will download and install Go version 1.24. You can check installed Go versions by running:
$ mise list
Activate new Go¶
Add ~/.local/share/mise/installs/go/X.Y.Z/bin to $PATH by executing:
$ eval "$(mise env -s bash go@1.24)"
or add the new $PATH to ~/.bash_profile to apply the environment automatically during every login:
$ mise env -s bash go@1.24 >> ~/.bash_profile
Install golangci-lint (optional)¶
After installing Go, you may want to install golangci-lint, a fast and flexible linter for Go projects:
$ mise exec go@1.24 -- go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
Once installed, you can verify it by running:
$ mise exec go@1.24 -- golangci-lint --version
Rebuild¶
- Reinstall Python:
To reinstall a specific version of Python, use:
$ TMPDIR=~/.tmp mise reinstall python@3.13
- Reinstall Node.js:
To reinstall a specific version of Node.js, use:
$ TMPDIR=~/.tmp mise reinstall node@22
- Reinstall Ruby:
To reinstall a specific version of Ruby, use:
$ TMPDIR=~/.tmp mise reinstall ruby-3.3
- Reinstall Gems:
To reinstall all gems for the current Ruby version, run:
$ gem pristine --all
- Reinstall Rust:
To reinstall a specific version of Rust, use:
$ TMPDIR=~/.tmp mise reinstall rust@1.76
- Reinstall Golang:
To reinstall a specific version of Go (Golang), use:
$ TMPDIR=~/.tmp mise reinstall go@1.24
Variables for Passenger¶
To set environment variables for your project, you can add them to the ~/.bash_profile file (e.g., export TESTENV=1). These variables will be visible to the application when launched by Passenger.
Warning
Variables will not be used from ~/.bashrc or ~/.shrc.
Plugins¶
Mise manages different programming language versions and runtimes using plugins. Most plugins are automatically installed when you install a language version, so you typically don’t need to install them manually.
Listing Available Plugins¶
To see a list of all available plugins in the Mise registry, run:
$ mise registry list
Installing a Language (Plugin Auto-Installation)¶
Plugins in Mise are automatically installed when you install a language version. For example, to install Lua 5.4:
$ TMPDIR=~/.tmp mise install lua@5.4
Mise will automatically fetch the Lua plugin if it isn’t already installed and then install Lua 5.4.
Listing Installed Plugins¶
To check which plugins are installed on your instantion, run:
$ mise plugins list
Updating Plugins¶
To update all installed plugins to their latest versions:
$ mise plugins update
To update a specific plugin:
$ mise plugins update lua
