crenv

Crystal version manager.

Install using anyenv

If you used anyenv, it might be very easy for you to install crenv !

$ anyenv install crenv
$ exec $SHELL -l

Install

$ git clone https://github.com/pine613/crenv ~/.crenv
$ echo 'export PATH="$HOME/.crenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(crenv init -)"' >> ~/.bash_profile
$ exec $SHELL -l

I recommend using crystal-build for installing Crystal itself. See also crystal-build.

$ git clone https://github.com/pine613/crystal-build.git ~/.crenv/plugins/crystal-build

If you installed crystal-build plugin, you may installed Crystal as following.

$ crenv install 0.7.4
$ crenv rehash
