Question

This issue might be related to cocoapods-docs. rake bootstrap fails due to cocoapods-docs ruby version requirement 2.0. Does this requirement can be changed to something like 2.0 or later?

Report

What did you do?

rake bootstrap

What did you expect to happen?

I expected to bootstrap and build CocoaPods and its dependencies.

What happened instead?

rake aborted with the following error while Bootstrapping cocoapods-docs :

To fix the above issue, I installed ruby 2.0.0-p648, and ran rake bootstrap. Then, I got another error:

An error occurred while installing json (1.7.7), and Bundler cannot
continue.
Make sure that `gem install json -v '1.7.7'` succeeds before bundling.
rake aborted!

Some projects like Xcodeproj use the forked json 1.7.7 gem and it seems ruby 2.0.0-p648 has some issue with it. So, I updated their Gemfiles to use the original json 1.7.7 as the issue 63 mentioned, and it fixes the above error. Even though I'm still seeing some rake aborted! messages, rake bootstrap can be complete now. I was wondering all these issues could be fixed if cocoapods-docs can be built with newer ruby.

The entire log is very long, so I posted it on my gist.

It would be great if I could hear opinions and suggestions from anyone who might know these issues. I would love to contribute to fix this issue as well! Thank you 😃

Yeah, I think it's fine to make that a > 2.0 in cocoapods-docs

[keitaito]

@orta Thanks you for the comment. OK, I will make a PR on cocoapods-docs 😃

@orta I tried the change you suggested locally, and it fixes the issue, but I got another error:

I think the different rake gem is used for bootstrapping. I checked Rainforest's Rakefile at line 117:

sh 'rake --no-search bootstrap' if rake_task?('bootstrap', :allow_bundler => false)

Do you think it should start with bundle exec? When I tried bundle exec rake bootstrap under the Molinillo directory, it succeeds.
