所以在使用Rails制作我的第一个脚手架之后,我试图访问它创建的一些页面,并得到以下错误:
ExecJS::RuntimeError in Users#index
Showing /Users/Alice/Desktop/sample_app/app/views/layouts/application.html.erb where line #6 raised:
dyld: unknown required load command 0x80000022
(in /Users/Alice/Desktop/sample_app/app/assets/javascripts/users.js.coffee)
Extracted source (around line #6):
3: <head>
4: <title>SampleApp</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8: </head>
9: <body></code>
我查了一下这个错误,我得出结论,我需要安装therubyracer gem。我试图通过gem install therubyracer来做到这一点。
然后我收到了错误:
ERROR: Error installing therubyracer:
ERROR: Failed to build gem native extension.

所以我运行gcc -version,我看到我的版本是i686-apple-darwin9-gcc-4.0.1 我试图使用MacPorts更新我的gcc,而我似乎无法使其完全正常工作......
我正在运行OSX Leopard,我猜这是我悲伤的原因 我该怎么办?
