Cocoapods: Error: can't modify frozen String

Created on 6 Oct 2013  Â·  10Comments  Â·  Source: CocoaPods/CocoaPods

I am using cocoapods with rubymotion. If i add the gem to the project, it raises this error.

There is a part of my project: https://gist.github.com/franciscomxs/6855012

The error appears when i add the gem, even if i don't really use it.

I have tried with a clean install of ruby 2.0 and 1.9.3.

The podspecs is in correct format, one week ago the specs are still passing. Just wonder is there any environment issue which cause this error?

@alloy Time to include my version class?

And I have never seen this error again...

@0wnrepo that's a separate issue that has been fixed in Molinillo already. Run gem install molinillo and in future please don't comment on closed issues.

@segiddins
Excuse me, how to solve this problem?
I have run gem install molinillo。But this error has not been resolved。

@864764448 I was able to fix this with gem install --pre cocoapods.
