我一直在尝试在我的macbook上安装rails,并且遇到了这么大的困难! 我安装了RVM,当我运行“gem install rails”时,我收到了这条消息:

gem install rails
Building native extensions.  This could take a while...
ERROR:  Error installing rails:
    ERROR: Failed to build gem native extension.

我尝试使用谷歌搜索解决方案,但没有找到任何东西。有人有想法吗?谢谢!

答案 0 :(得分:0)

你得到的错误有一个有趣的路线:

ld: library not found for -lruby.1.9.1

这让我觉得您的ruby安装存在问题。

似乎在Mac计算机上存在Xcode和ruby安装问题(请参阅此问题here,以及关于此问题的文章here)。

重新安装ruby应该让思考工作。
