--no-document rdoc,ri causes error

[swills]

Using the --no-document rdoc,ri flag causes error:

This also doesn't happen if you use --no-rdoc --no-ri.

Hi! So, this issue's a year old, but I'll explain what's up in case you or anyone else runs into a similar problem in the future and finds this issue:

It looks like either you were using the --no-document flag improperly, or its usage has changed in the past year.

The way --document and --no-document work, you want to specify either --no-document or --document [TYPES]. --no-document doesn't accept a list of types.

I'm not sure what it was doing before to yield that error, but now it treats gem install x --no-document rdoc,ri the same as gem install x rdoc,ri --no-document and raises an error about being unable to install the rdoc,ri gem.

I'm closing this issue, since it can be resolved by simply removing rdoc,ri from the command line arguments. Sorry it took so long for you to get a response!
