我已经搜索了一段时间，但无法解决问题。我在一台相对较新的计算机（osx）上，到目前为止只在其上创建了一个 rails 应用程序。直到现在一切都很顺利。我现在正在尝试使用

rails new appname

这是终端向我展示的内容：

Installing tilt (1.4.1) 
Errno::EACCES: Permission denied - /Library/Ruby/Gems/1.8/build_info/tilt-1.4.1.info
An error occurred while installing tilt (1.4.1), and Bundler cannot continue.
Make sure that `gem install tilt -v '1.4.1'` succeeds before bundling.

当我进入

gem install tilt -v '1.4.1'

我得到以下信息：

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/1.8 directory.

在搜索时，我发现有类似外观错误的人，但我找不到任何解决我的具体问题的方法。

我正在使用 ruby​​ 2.0.0 和 rails 2.3.13。

我真的卡住了，希望有人知道如何解决这个问题。提前致谢！

更新：我注意到，当我运行 rails new app 命令时，终端问我

Enter your password to install the bundled RubyGems to your system:

它以前从未这样做过。有没有可能我改变了系统上的某些东西？

Update2：据我所知，在使用 2 天以上之后，解决方案是完全重新安装最新版本的 ruby​​ 和 rails。

尝试sudo 或在您可以访问的目录中创建您的应用程序

如果 sudo "gem installtilt -v '1.4.1'" 不起作用。那么最有可能的是，“其他”组在您的 Ruby 安装中没有正确的权限。确保您为 group=others 或运行以下命令的用户提供正确的权限：
