rails generate devise:install hangs

Felender Hlungwani asked in Rails

I ran into this issue today whilst I was trying to deploy jumpstart template into my Rails 5.2.1 App

When I ran rails generate devise:install nothing happened. No errors, no output – nothing. Normally, this completes in seconds. In the end I aborted the rails generate task with a Ctrl-C. I noticed that the following output was barfed out to the screen:

generate  devise:install

I didn’t think anything of this at first, and assumed I had a dodgy install of devise, or rails or something.

So I uninstalled and reinstalled devise, warden and rails – and reran rails generate devise:install.

Nothing happened. I hit Ctrl-C, and got the same

Try running "spring stop" in the new app folder, delete the folder, and then try again. Spring will cache files like that and do weird things.

I resolved the problem by doing the following:

gem uninstall fileutils
Successfully uninstalled fileutils-1.1.0
gem update --default
Updating installed gems
Updating fileutils
Fetching: fileutils-1.1.0.gem (100%)
Successfully installed fileutils-1.1.0
