ruby - 无法在 OS X El Capitan 上安装 capybara-webkit

Question

升级到 El Capitan 后，我在安装 capybara-webkit 时遇到问题。 QT 版本 qt-4.8.7_1 已经安装。 bundle install 给出权限错误，sudo gem install 给出另一个错误:

捆绑安装:

Installing capybara-webkit 1.7.1 with native extensions

Errno::EACCES: Permission denied @ rb_sysopen - /usr/local/lib/ruby/gems/2.2.0/gems/capybara-webkit-1.7.1/.gitignore
An error occurred while installing capybara-webkit (1.7.1), and Bundler cannot continue.
Make sure that `gem install capybara-webkit -v '1.7.1'` succeeds before bundling.

gem 安装:
