从终端

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

Gem files will remain installed in /Users/dan/.rvm/gems/ruby-2.0.0-p0/gems/fastthread-1.0.7 for inspection.

不明白这个错误，为什么会出现两次？任何指导表示赞赏。

Answer 1

安装乘客 4 beta 的命令为gem install passenger -v 4.0.0.rc4我解决了这个错误。

Answer 2

乘客 3.0.19（您获得的默认版本gem install）还没有为 ruby​​ 2 做好准备。要么使用 ruby​​ 1.9.3，要么使用当前的乘客 4 测试版。
