Running brew generates warnings
提问by Chiron
I installed the latest Homebrew on OS X 10.6.5
Running any command generates this warning:
我在 OS X 10.6.5 上安装了最新的 Homebrew
运行任何命令都会生成此警告：
/usr/local/Library/Homebrew/global.rb:34: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777
/usr/local/Library/Homebrew/global.rb:34: 警告：不安全的世界可写目录 /usr/local/bin 在 PATH，模式 040777
Why I'm getting this warning? and how to remedy?
为什么我会收到此警告？以及如何补救？

I had the same problem and just fixed it with these 3 commands, roughly taken from Homebrew installation script:
我遇到了同样的问题，只是用这 3 个命令修复了它，大致取自 Homebrew 安装脚本：
sudo chgrp -R admin /usr/local
sudo chmod -R g+rwx /usr/local
sudo chmod -R o-w /usr/local

First, there are two brew commands that are helpful when debugging problems. They are:
首先，有两个 brew 命令在调试问题时很有帮助。他们是：
$ brew doctor
$ brew missing
Second, Homebrew is telling you that /usr/local/binis set to be too permissive in who can write to that directory -- a potential security problem. To remedy this, you can reset your permissions back to what Homebrew intended.
其次，Homebrew 告诉您，/usr/local/bin谁可以写入该目录的设置过于宽松——这是一个潜在的安全问题。为了解决这个问题，您可以将您的权限重置回 Homebrew 的意图。
$ chmod 755 /usr/local/bin
If you get an error while trying to do this, it may mean that your /usr/local directory (and subdirectories) are owned by the wrong user. If that's the case, I would consider deleting your /usr/local directory and reinstalling Homebrew correctly. Alternatively, you can override the error by prefixing the last command with sudo and entering your admin password:
如果您在尝试执行此操作时遇到错误，则可能意味着您的 /usr/local 目录（和子目录）归错误的用户所有。如果是这种情况，我会考虑删除您的 /usr/local 目录并正确重新安装 Homebrew。或者，您可以通过在最后一个命令前面加上 sudo 并输入您的管理员密码来覆盖错误：
$ sudo chmod 755 /usr/local/bin

This is a security feature of ruby, you can change permissions on the directory /usr/local/bin to get rid of this by running:
这是 ruby 的一个安全特性，您可以通过运行更改目录 /usr/local/bin 的权限来摆脱它：
sudo chmod go-w /usr/local/bin
and entering your password on the prompt.
并在提示中输入您的密码。
You do notneed to change ownership and neithershould delete /usr/local as Ryan suggested (that would require you to rebuild everything you′ve accomplished so far), the directory is owned by root and this is the usual way.
你没有必要改变所有权，也不应删除的/ usr / local作为瑞安建议（这将需要您重建一切你所取得的成就），该目录由root拥有，这是通常的方式。
