I'm struggling with the following error for a few days when precompiling my assets:

NoMethodError: undefined method `mtime' for nil:NilClass

Any ideas of what may be causing this error?

[carsomyr]

@rwillrich Most likely incorrect use of Bower. See #188.

[rwillrich]

I'm using requirejs-rails version 0.9.5 with Bower and saving my dependencies to vendor/assets/components directory.

I used this same setup on a different project and it worked.

[carsomyr]

@rwillrich Could you follow the steps taken in #188 and let me know which asset is failing?

[rwillrich]

Where do I put the puts to show the assets that are being processed?

[carsomyr]

Sprinkle some putss in this region.

[rwillrich]

It was with sammy, on its bower.json file, the main path was absolute, and this was causing the error.

I've already sent a PR to them to fix this.

Thanks!

[carsomyr]

@rwillrich Great to hear!

[akholodenko]

Same issue - confirming removing a bower.json file fixed things.
