How to build PrototypeJS from source?

Question

I cloned prototype.js repository, but when i trying to build, i get the error:

rake aborted!
uninitialized constant Sprockets::Secretary

What is the reason?

Answer 1

I was also having this problem.

Try using a different version of sprockets.

gem uninstall sprockets, gem install sprockets --version 1.0.2

1.0.2 was the version that worked for me.
