Question

I recently updated my Mac Mini to OS 10.8 Mountain Lion, and using Ruby gems with RVM 1.16.8, Ruby 1.9.3p194 no longer works.

Here is the concise version of the error:

`load_api_keys': undefined method `key?' for #<String:0x007f865a928a28> (NoMethodError)

When I run any command like gem install bundler or gem -v I get the error below:

➜  ~ gem

I have gone in and commented out the conflicting method call load_api_keys which makes things function properly, but it then breaks any interaction with rubygems.org.

The issue is line :227, if @api_keys.key? :rubygems_api_key then

def load_api_keys
  @api_keys = if File.exist? credentials_path then
                load_file(credentials_path)
              else
                @hash
              end
  if @api_keys.key? :rubygems_api_key then
    @rubygems_api_key = @api_keys[:rubygems_api_key]
    @api_keys[:rubygems] = @api_keys.delete :rubygems_api_key unless @api_keys.key? :rubygems
  end
end

After removing RVM and attempting to install different Rubies, I have not found a solution to this issue. I do not want to simply comment out something that removes functionality that I use.

If anyone could give any insight as to what is causing this and how to fix it, it would be much appreciated.

Answer 1

Remove (or move) /Users/brettchalupa/.gem/credentials and let it use the default credentials.
