ruby - Fast-stemmer 安装问题

Question

由于 fast-stemmer 的问题，我很难安装我想要的任何 ruby​​ gem。我把我得到的错误放在下面。

Building native extensions.  This could take a while...
ERROR:  Error installing fast-stemmer:

我尝试解决问题的一些事情包括:更新 ruby​​ gems、更新 rvm、使用 ruby​​ 2.1.1、重新安装命令行工具。我在小牛队。

如果有人能帮助我，我将不胜感激!

所以，看来我遇到的问题是由更新最后一个 xCode 引起的，它又将 clang 更新为 5.1，这又破坏了许多尚未更新以反射(reflect) clang 中的重大变化的 ruby​​ gem 5.1.我在 Cloudspace blog 上找到了这一切.

他们的解决方案(目前——错误说他们将来会变成硬错误)是放置以下标志让你的编译器忽略这个问题:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

例如:

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install librarian-chef

或捆绑:

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future bundle install
