warning: circular argument reference - browsers with mri 2.2.0

[salimane]

After upgrading to mri 2.2.0, I'm getting some warnings :

/usr/local/rvm/gems/ruby-2.2.0-rc1@project/gems/compass-core-1.0.1/lib/compass/core/caniuse.rb:72: warning: circular argument reference - browsers

This happens because of https://github.com/Compass/compass/blob/stable/core/lib/compass/core/caniuse.rb#L72

  # returns the prefixes needed by the list of browsers given
  def prefixes(browsers = browsers)
    result = browsers.map{|b| all_prefixes(b) }
    result.flatten!
    result.uniq!
    result.sort!
    result
  end

Thanks

browsers = browsers should be changed to browsers = browsers(), see https://bugs.ruby-lang.org/issues/10314

[salimane]

the pr #1903 should fix it.

Another vote for "gem update" to fix the problem - I had this problem and updating the gems fixed it.

Ran into this problem and this was my solution

$ gem uninstall compass $ gem update --system $ gem install compass
