我在将要在Rails 4.2.10中进行工作的一个项目中进行捆绑安装时遇到了麻烦。当我捆绑时，我收到下一个错误:
安装ffi(1.9.25)时发生错误，并且Bundler无法继续。
捆绑之前，请确保gem install ffi -v '1.9.25'成功。
In Gemfile:
s3_direct_upload was resolved to 0.1.6, which depends on
sass-rails was resolved to 5.0.7, which depends on
sass was resolved to 3.6.0, which depends on
sass-listen was resolved to 4.0.0, which depends on
rb-inotify was resolved to 0.9.10, which depends on
ffi
当我运行gem
install ffi -v '1.9.25'时，也会发生错误:Building native extensions. This could take a while...

我一直在尝试许多在线解决方案，但无法解决此问题。
似乎问题出在我的系统上，因为我是团队的新手，而其他开发人员也没有帮助，因为他们没有这种问题。
最佳答案
我能够使用以下命令成功安装ffi:
LDFLAGS="-L/usr/local/opt/libffi/lib" PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig" gem install ffi -v '1.9.25'
