启动rails服务器时出错：警告：PATH中不安全的世界可写目录/ usr，模式040777 [重复]答案

【问题标题】：Error when starting rails server: warning: Insecure world writable dir /usr in PATH, mode 040777 [duplicate]启动rails服务器时出错：警告：PATH中不安全的世界可写目录/ usr，模式040777 [重复]

【问题描述】：

我正在关注 Treehouse 上的 Ruby 教程，但在启动 rails 服务器时不断收到以下错误：

/usr/local/rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.2.4/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777
/usr/local/rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.2.4/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777

我尝试使用 sudo chmod o-w /usr/local/ 修复和其他变体，但遗憾的是这对我没有任何作用。

即使出现该错误，尽管服务器仍会启动并且一切正常，但是现在我也遇到了很多其他错误，服务器甚至不再启动，我认为它们可能会以某种方式连接？

这是我现在得到的错误：

有什么解决这个问题的建议吗？我尝试重新安装 Rails，但没有帮助，仍然是同样的错误。

谢谢！

【问题讨论】：

你的 app/models/user.rb 看起来如何？
你有一个意外的关键字结尾，所以用ruby -c app/models/FILENAME.rb检查你的模型文件的语法

标签： ruby-on-rails ruby terminal

【解决方案1】：

尝试从磁盘实用程序中选择“修复磁盘权限”

[编辑]

对于 OS X El Capitan：

sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /

【讨论】：

你需要更多的支持！
谢谢，这解决了更新到 OS X 10.9.3 后安装 ruby gem 的类似问题。
在 OS X 上安装 10.9.3 更新后，这个问题浮出水面，我可以使用磁盘实用程序中的“修复磁盘权限”修复它。谢谢！
@Wazery 谢谢先生，我已经访问了 4 个主题，这解决了我的问题。我已为您投票，并将您的答案发布到其他主题。
不错 :) 这么简单的事情就出现在 GUI 上。我在 CLI 中四处搜索变得疯狂（找不到任何可写的世界）。

【解决方案2】：

使用-R（用于递归）尝试您的 chmod：

chmod -R o-w /usr/local/

【讨论】：

谢谢，chmod 命令对我不起作用，但我在磁盘工具中修复了磁盘权限并修复了它。
修复磁盘工具也对我有用。谢谢。 :)
@CorySimmons：介意突出显示您的 OSX 版本吗？（在我的情况下（雪豹或狮子，不记得它发生的时间，当我遇到错误时，它不起作用。）
我尝试了 Disk Util 方法，效果很好。然后我尝试了@Denis 在这里提到的内容。这为我解决了它。谢谢

【解决方案3】：

关于警告：

... warning: Insecure world writable dir /usr in PATH, mode 040777
... warning: Insecure world writable dir /usr in PATH, mode 040777

他们告诉你目录/usr（而不是/usr/local）是世界可写的。修复：chmod -R go-w /usr。

错误说：

... `load': /Users/yassine/treebook/app/models/user.rb:12: syntax error, unexpected keyword_end (SyntaxError)

user.rb 文件的第 12 行有一个额外的 end 关键字。

【讨论】：

非常感谢！我现在可以启动服务器，chmod 命令对我不起作用，但我在磁盘工具中修复了磁盘权限并修复了它。我在 user.rb 文件中有一个额外的逗号导致其他错误。
“chmod -R go-w /usr.”中的“go”是什么？
@AlexanderSupertramp go 表示群组和其他人，请参阅man 1 chmod 了解更多详情。
