我正在关注 the rails tutorial 上的教程现在正在第三章(静态页面)。当我尝试立即执行 list 3.1 下的bundle install 时，该命令会抛出一条错误消息，指示链接失败。错误的片段如下所示:
Using bundler (1.2.1)

Gem files will remain installed in /home/user/.gem/gems/ffi-1.1.5 for inspection.
Results logged to /home/user/.gem/gems/ffi-1.1.5/ext/ffi_c/gem_make.out
An error occurred while installing ffi (1.1.5), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.1.5'` succeeds before bundling.
据我所知，通过添加正确的 pthread 库(-lpthread)可以轻松解决这个问题。但我的问题是，我该在哪里添加这个？我看到很多在 MAC OS X 上解决这个问题的问题，但没有一个是针对 Linux 的。任何帮助表示赞赏。
最佳答案
将“dev-lang/ruby 线程”添加到我的 package.use 并重建 dev-lang/ruby
关于ruby-on-rails - Ruby on Rails : cannot install FFI 1. 1.5 和捆绑程序无法继续，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13183282/
