Question

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，到目前为止只创建了一个rails应用程序。到现在为止一切顺利。我现在正在尝试使用

创建一个新的应用程序

rails new appname

这是终端告诉我的：

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'

我得到以下内容：

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

在搜索时，我发现人们看起来有类似错误，但我找不到解决我具体问题的方法。

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。提前谢谢！

更新：我注意到，当我运行rails new app命令时，终端会问我

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

之前从未这样做过。我有可能在系统上改变了一些东西吗？

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

Answer 1

尝试sudo 或者在您可以访问的目录中创建您的应用

Answer 2

尝试sudo gem install tilt -v '1.4.1'

Answer 3

如果sudo“gem install tilt -v'1.4.1'”不起作用。然后大多数人都喜欢，“其他人”组在你的Ruby旅馆中没有正确的权限。请确保您为group = others或运行该命令的用户提供了正确的权限：

/Library/Ruby/Gems/1.8

由于权限，Rails新应用程序失败
