Elm 0.19 just came out, so the npm
installer is not ready yet. In the meantime, you can download it manually like this:
wget "https://github.com/elm/compiler/releases/download/0.19.0/binaries-for-linux.tar.gz"
tar xzf binaries-for-linux.tar.gz
mv elm /usr/local/bin/
Moving the binary to /usr/local/bin
should make it available on your PATH
so you can call it from anywhere.
Congrats for this new version ! Do you plan to continue to distribute this binary even when the npm installer will be ready ? It's nice to just have a binary to copy and not to deal with npm :)
