How do I fix this error? config.gem: Unpacked gem authlogic-2.1.3 in vendor/gems has no specification file

I am not sure why it is broken in Authlogic, but I had to generate it myself.

Try this in your Rails project:

$prompt> cd vendor/gems/authlogic-2.1.3

$prompt> gem specification authlogic > .specification

I'm just going to chime in here, because I experience the same thing today, except with a different gem.

I was updating hoptoad to use the notifier as a gem instead of a plugin, and one of the instructions from the Github page is to unpack the gem into vendor/gems.

I'm on Mac OS X, and I unpacked the gem as so:

$> rake gems:unpack GEM=hoptoad_notifier

After I did this, I got the error specified, and the gem didn't actually unpack (it created the directory in vendor/gems, but didn't actually unpack the gem).

I deleted the directory from vendor/gems, and tried again as:

$> sudo rake gems:unpack GEM=hoptoad_notifier

Worked this time, unpacked properly, and no error.

I believe this is the reason:http://github.com/binarylogic/authlogic/commit/05e452472616bd60bb81affc75a1cb3d95cf7857

The owner purposely added the gitignore on the .specification file.I'm guessing u freeze this particular gem and submit it in your code branch under vendor/gems/..and as expected, git ignore this particular file per request
