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

我正在尝试编辑 PATH 的条目，因为我做错了什么.

我使用的是 Mac OS X v10.10.3 (Yosemite)

我试过了:

touch ~/.bash_profile;打开 ~/.bash_profile

但是文件编辑器打开时里面什么也没有.

我的问题:

我正在尝试将 ANDROID_HOME 安装到我的 PATH

我拼错了，但是当我关闭终端并返回时它不见了，所以我又试了一次:

<块引用>

export ANDROID_HOME=/<安装位置>/android-sdk-macosx导出路径=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

这一次，我正确输入了命令，但是当我关闭终端时，我的设置又消失了.

如何执行我想要的设置?

如果我要编辑 bash.profile，我该如何输入上面的代码?

解决方案

您必须使用文本编辑器打开该文件，然后将其保存.

touch ~/.bash_profile;打开 ~/.bash_profile

它将使用 TextEdit 打开文件，粘贴您的内容，然后保存.如果您再次打开它，您会发现您所做的编辑.

您可以使用其他编辑器:

nano ~/.bash_profile队友 ~/.bash_profilevim ~/.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.

或者，您可以依赖 pbpaste.复制

export ANDROID_HOME=/<安装位置>/android-sdk-macosx导出路径=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

在系统剪贴板中，然后在 shell 中运行

pbpaste >~/.bash_profile

---

或者你也可以使用 cat

cat >~/.bash_profile

(现在 cat 等待输入:粘贴两个导出定义，然后按 Ctrl + D).

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

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

I have tried:

touch ~/.bash_profile; open ~/.bash_profile

But the file editor opens with nothing inside.

My problem:

I am trying to install ANDROID_HOME to my PATH

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

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

How do I execute my desired settings?

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

解决方案

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

touch ~/.bash_profile; open ~/.bash_profile

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

You can use other editors:

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

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

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

in the system clipboard and then in a shell run

pbpaste > ~/.bash_profile

---

Or alternatively you can also use cat

cat > ~/.bash_profile

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