快速词干安装问题

Question

由于fast-stemmer 的问题，我很难安装任何我想要的 ruby​​ gem。我已经把我得到的错误放在下面。

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

我尝试解决的问题包括：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。

如果有人可以帮助我，将不胜感激！

因此，我遇到的问题似乎是由更新最后一个 xCode 引起的，该 xCode 又将 clang 更新到 5.1，这反过来又破坏了许多尚未更新的 ruby​​ gem，以反映 clang 的重大变化5.1。我在Cloudspace blog 上找到了这一切。

他们的解决方案（目前 - 错误表明它们将来会成为硬错误）是放置以下标志以让您的编译器忽略该问题：

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
