Working with mise

To fix command not found errors for Node.js or Python, you need to manage tool versions using a version manager like mise, which activates the correct environment when you enter a project directory.

The best way to manage multiple programming language versions across projects is using a polyglot tool manager like mise, which configures specific Node.js, Python, or Ruby versions per project directory.

You can install a specific Node.js version for your current development project by using mise to manage configuration files, ensuring the required version is available and automatically activated in your shell.

You should use mise over a system package manager like Homebrew when you need to switch between different versions of languages like Python or Ruby across multiple projects to prevent version conflicts.

Your mise managed tools are not available in your current shell session because shell activation is incomplete; you must configure shell integration properly to ensure the environment variables load correctly.
