如何在OS X上编辑$ PATH(.bash_profile)? [英] How do I edit $PATH (.bash_profile) on OS X?

问题描述

由于我做错了什么，我正在尝试编辑PATH条目.

I am trying to edit an entry to PATH, as I did something wrong.

我正在使用 Mac OS X v10.10.3 (Yosemite)

I am using Mac OS X v10.10.3 (Yosemite)

我尝试过:

touch ~/.bash_profile; open ~/.bash_profile

但是文件编辑器将打开，里面没有任何内容.

But the file editor opens with nothing inside.

我的问题:

我正在尝试将ANDROID_HOME安装到我的PATH

I am trying to install ANDROID_HOME to my PATH

我拼错了，但是当我关闭终端并返回时，它消失了，所以我再次尝试:

I misspelled it, but when I closed the terminal and went back it was gone, so I tried again:

export ANDROID_HOME=/<installation location>/android-sdk-macosx
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

这一次，我正确键入了命令，但是，当我关闭终端时，我的设置又消失了.

This time, I typed the command correctly but, when I closed the terminal, my settings disappeared again.

如何执行所需的设置?

如果我要编辑bash.profile，如何输入上面的代码?

If I was to edit bash.profile, how would I enter the above code?

推荐答案

您必须使用文本编辑器打开该文件，然后保存.

You have to open that file with a text editor and then save it.

touch ~/.bash_profile; open ~/.bash_profile

它将使用 TextEdit 打开文件，粘贴您的内容然后保存.如果再次打开它，您将找到您的编辑内容.

It will open the file with TextEdit, paste your things and then save it. If you open it again you'll find your edits.

您可以使用其他编辑器:

You can use other editors:

nano ~/.bash_profile
mate ~/.bash_profile
vim ~/.bash_profile

但如果您不知道如何使用它们，则使用 open 方法会更容易.

But if you don't know how to use them, it's easier to use the open approach.

或者，您可以依赖 pbpaste .复制

Alternatively, you can rely on pbpaste. Copy

export ANDROID_HOME=/<installation location>/android-sdk-macosx
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

在系统剪贴板中，然后在shell中运行

in the system clipboard and then in a shell run

pbpaste > ~/.bash_profile

---

或者，您也可以使用 cat

cat > ~/.bash_profile

(现在 cat 等待输入:粘贴两个导出定义，然后按 Ctrl + D ).

(now cat waits for input: paste the two export definitions and then hit Ctrl + D).
