Question 1

How do I install a specific Crystal version with crenv?

Accepted Answer

First, ensure you have the crystal-build plugin installed. Then, use 'crenv install ' to install the version, followed by 'crenv global ' to set it globally. Remember to run 'crenv rehash' after installation to update shims.

Question 2

crenv vs asdf: which is better for Crystal version management?

Accepted Answer

crenv is a dedicated, lightweight tool for Crystal, ideal if you're already using anyenv or prefer a minimalist approach. asdf is a multi-language version manager that supports Crystal via plugins, making it better for polyglot teams who want a single tool. Choose based on whether you need Crystal-specific focus or broader language support.

Question 3

How to switch Crystal versions for a specific project using crenv?

Accepted Answer

Navigate to your project directory and use 'crenv local <version>' to set a local version. This creates a .crystal-version file that crenv reads to automatically switch versions when you're in that directory, ensuring project-specific compatibility.

Question 4

Does crenv work on Windows?

Accepted Answer

crenv is primarily designed for Unix-like systems (Linux, macOS) and relies on shell environments. It might work on Windows with WSL or Cygwin, but native support is limited, and setup can be more complex due to shell dependency.

Question 5

How to update crenv to the latest version?

Accepted Answer

To update crenv, go to its installation directory (~/.crenv or ~/.anyenv/envs/crenv) and run 'git pull origin master'. Also, update the crystal-build plugin by navigating to plugins/crystal-build and doing the same, as per the README instructions.

Question 6

What's the difference between crenv and crystalbrew?

Accepted Answer

crenv is inspired by rbenv and uses a shim-based approach for minimalism, while crystalbrew is another Crystal version manager with potentially different workflows. crenv emphasizes integration with anyenv and clean code, whereas crystalbrew might offer alternative features; check the README's 'See also' section for details.
