如何从 Mac 上的 $PATH 中删除条目 [英] How to remove entry from $PATH on mac

问题描述

我尝试安装 Sencha Touch SDK 工具 2.0.0，但无法正常运行.它在 $PATH 变量中创建了一个条目.后来我删除了sencha sdk工具文件夹，但没有意识到路径变量仍然存在.

I was trying to install Sencha Touch SDK tools 2.0.0 but could not run it properly. It created an entry in the $PATH variable. Later I deleted the sencha sdk tools folder but didn't realize that the path variable is still there.

当我做 echo $PATH 我得到 -

/Applications/SenchaSDKTools-2.0.0-beta3:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

我搜索了如何从 $PATH 中删除变量并按照以下步骤操作:

I searched on how to remove variables from $PATH and followed these steps :

1. 给出命令PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin"
2. Did echo $PATH 显示 /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
3. 给出命令export PATH
4. 关闭终端并重新打开它.给出命令 echo $PATH.这次我得到/Applications/SenchaSDKTools-2.0.0-beta3:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

1. Gave the command PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin"
2. Did echo $PATH which showed /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
3. gave the command export PATH
4. Closed terminal and reopened it. Gave the command echo $PATH. This time I got /Applications/SenchaSDKTools-2.0.0-beta3:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

谁能告诉我我做错了什么?

Can anyone tell me what am i doing wrong?

推荐答案

您所做的对当前会话有效(仅限于您正在使用的终端).您需要坚持这些更改.考虑将上述步骤 1-3 中的命令添加到您的 ${HOME}/.bashrc.

What you're doing is valid for the current session (limited to the terminal that you're working in). You need to persist those changes. Consider adding commands in steps 1-3 above to your ${HOME}/.bashrc.
