actions.rb:12:in `replace_in_file' (RuntimeError)

[larrywhy]

Hello xdite! I am reading the book Rails 101 (old version)
The bootstrappers gem I installed has some problem that I do not know how to fix.

When I start this command: bootstrappers groupme
It start installing related gem until one problem happened.
I have searched for a long time . I still can not find any solution about this problem.
Here is the error message (While creating the seo_helper.rb gem , the error happened):
.........
