In Terminal, type which node, then create a symlink to that location in /usr/bin. For example, if node lives in /usr/local/bin, create the symlink like so: sudo ln -s /usr/local/bin/node /usr/bin/node If you look at the source of your coffee script, you’ll probably find that the first line is something along the lines of: #!/usr/bin/env … Read more
