如何在Mac上从$ PATH删除条目 [英] How to remove entry from $PATH on mac

问题描述

我试图安装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 tools文件夹，但没有意识到path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.

当我做了echo $PATH时，我得到了-

When i did echo $PATH I got -

/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，并遵循以下步骤:

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

1. 发出命令PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin"
2. 显示了/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
的echo $PATH
3. 发出命令export PATH
4. 关闭终端，然后重新打开.给了命令echo $PATH.这次我得到了 /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

有人可以告诉我我在做什么错吗?

Can anyone tell me what am i doing wrong?

推荐答案

您正在执行的操作对于当前会话有效(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.
