Question

我一直在尝试使用OS X El Capitan在我的Mac上安装gem，therubyracer用于rails应用程序，但是我一直收到与-rdynamic标志相关的错误，导致无法构建本机扩展。

Amory:coursequestionbank masonscott$ gem install therubyracer
Building native extensions.  This could take a while...
ERROR:  Error installing therubyracer:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/masonscott/.rvm/gems/ruby-2.2.1/gems/therubyracer-0.12.2 for inspection.

我已经尝试过到处搜索，似乎编译器应该忽略rdynamic标志，但由于某种原因，我没有。我尝试通过gcc更新到gcc5，但仍然无法解决问题。我该怎么做才能解决这个问题？

Answer 1

我在安装therubyracer时遇到问题（因为libv8存在问题）。我想你可以试试这个。

$ gem uninstall libv8
$ gem install therubyracer -v '0.12.0'

另一种方式如下

gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.3' -- --with-system-v8

并进行捆绑安装。我认为它可以解决你的问题。

由于mac上的编译器问题而无法安装therubyracer gem？
