How to modify PATH for Homebrew?
提问by mrdavidjcole
Trying to install ruby 1.9.3, read that I need to install homebrew first. Ran brew doctor, and it's giving me a bunch of warnings. One of which is:
尝试安装 ruby 1.9.3，阅读我需要先安装自制软件。Ran brew doctor，它给了我一堆警告。其中之一是：
Warning: /usr/bin occurs before /usr/local/bin This means that system-provided programs will be used instead of those provided by Homebrew. The following tools exist at both paths:
easy_install easy_install-2.6Consider amending your PATH so that /usr/local/bin is ahead of /usr/bin in your PATH.
警告：/usr/bin 出现在 /usr/local/bin 之前这意味着将使用系统提供的程序而不是 Homebrew 提供的程序。两个路径中都存在以下工具：
easy_install easy_install-2.6考虑修改您的 PATH，以便 /usr/local/bin 在您的 PATH 中位于 /usr/bin 之前。

open your /etc/paths file, put /usr/local/bin on top of /usr/bin
打开您的 /etc/paths 文件，将 /usr/local/bin 放在 /usr/bin 之上
$ sudo vi /etc/paths
/usr/local/bin
/usr/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin
and Restart the terminal, @mmel

There are many ways to update your path. Jun1st answer works great. Another method is to augment your .bash_profileto have:
有很多方法可以更新您的路径。Jun1st 答案效果很好。另一种方法是增加你的.bash_profile：
export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH"
The line above places /usr/local/binand /usr/local/sbinin front of your $PATH. Once you sourceyour .bash_profileor start a new terminal you can verify your path by echo'ing it out.
上述场所的线/usr/local/bin和/usr/local/sbin在你的面前$PATH。一旦你采购你.bash_profile或启动一个新的终端，你可以验证你的路径回声“荷兰国际集团出来。
$ echo $PATH
/usr/local/bin:/usr/local/sbin:/Users/<your account>/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
Once satisfied with the result running $ brew doctoragain should no longer produce your error.
一旦对结果感到满意，$ brew doctor再次运行应该不再产生您的错误。

To avoid unnecessary duplication, I added the following to my ~/.bash_profile
为了避免不必要的重复，我在 ~/.bash_profile 中添加了以下内容
case ":$PATH:" in
*:/usr/local/bin:*) ;; # do nothing if $PATH already contains /usr/local/bin
*) PATH=/usr/local/bin:$PATH ;; # in every other case, add it to the front

open bash profile in textEdit
在 textEdit 中打开 bash 配置文件
open -e .bash_profile
打开 -e .bash_profile
Edit file or paste in front of PATH export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/local/bin:/usr/local/sbin:~/bin
编辑文件或粘贴在PATH前面导出PATH=/usr/bin:/usr/sbin:/bin:/sbin: /usr/local/bin:/usr/local/sbin:~/bin
save & close the file
保存并关闭文件
*To open .bash_profile directly open textEdit > file > recent
*要打开 .bash_profile 直接打开 textEdit > 文件 > 最近
