无法安装 ffi gem，Rails 失败
在通过railsgenerateintegration_testfoo创建集成测试时，它拒绝了，
Could not find ffi-1.0.9 in any of the sources
Run `bundle install` to install missing gems.
我运行bundleinstall来安装缺少的gems，但没有成功。还是同样的错误。我的 Gemfile 中有 gem 'ffi' 。
我将 gemfile 行切换为 gem 'ffi', :git => 'git://github.com/ffi/ffi.git' 并再次捆绑安装。它做了各种各样的事情，并在最后写道“您的捆绑包已完成”。
但是，当我再次运行 railsgenerate... 命令时，我得到：
git://github.com/ffi/ffi.git (at master) 未签出。请运行“bundle install”
这个 ffi 到底是怎么回事？
While creating creating an integration test via rails generate integration_test foo it declined with
Could not find ffi-1.0.9 in any of the sources
Run `bundle install` to install missing gems.
I ran bundle install to install missing gems, but with no success. Still the same error. I have gem 'ffi' in my Gemfile.
I switched the gemfile line to gem 'ffi', :git => 'git://github.com/ffi/ffi.git' and bundle installed again. It did all sort of stuff and wrote "Your bundle is complete" at the end.
However when I run the rails generate... command again I get:
git://github.com/ffi/ffi.git (at master) is not checked out. Please run 'bundle install'
What the hell is going on with this ffi?

我遇到了同样的问题，并通过删除
Gemfile.lock并重新运行bundle install解决了它。I ran into the same problem and solved it by removing the
Gemfile.lockand re-runbundle install.也许尝试“bundle execrailsgenerate...”
Perhaps try 'bundle exec rails generate...'
捆绑包安装失败，因为它可能因规范的 NoMethodError 而失败。
删除 Gemfile.lock，清空 gemset 并进行捆绑安装工作。
bundle install was failing because it could ffi failed with NoMethodError for spec.
Removing Gemfile.lock, empty the gemset and doing bundle install worked.
