Installing Crystal locally

Learn how to install Crystal locally to solve Exercism's exercises on your own machine

Crystal is available on Linux, macOS, and Windows.

What to note is that Crystal's Windows support is experimental. Meaning there might be some edge cases which don't work and it might not be ideal for production use cases. However, for Exercism and basic usage, native Windows should be largely usable.

If you are looking for a non preview experience for Windows development, it is recommended to use WSL (Windows Subsystem for Linux). It is a free feature of windows 10(1903+) and 11 which allows developer to run a linux environment without the need of a virtual machine.

Use one of the installation guides for instructions on installing Crystal.
