The glitch “add package” button tries to get you to install coffeescript version 99.999.99999, which has been deprecated.
Apparently, the package owner used to use this package to point users to the “coffee-script” package, but later decided to actually use “coffeescript” for the package name.
Is it possible to have glitch ignore deprecated versions of packages? (Even if they have bigger version numbers.)
The work-around is to manually enter a proper version like “2.3.2” in package.json. However, this might be confusing to new users and the notification about version “99.999.99999” of coffee-script in the “add package” button is annoying.
