推荐答案

我有一个解决方案给你！希望.

I have a solution for you! Hopefully.

前几天也遇到了同样的问题.

Had this same problem the other day.

问题在于 El Capitan 捆绑的 clang 编译器.我确信它会解决其他问题，但这是我遇到很多问题的一点.

The problem is in the clang compiler that El Capitan comes bundled with. I'm sure it screws up other issues but this is one point that I had a lot of issues with.

尝试运行以下命令，让我知道结果如何！

Try running the following command and let me know how it goes!

gem install thrift -- --with-cppflags="-D_FORTIFY_SOURCE=0 -Wno-shift-negative-value"
