（Mac）-bash：__git_ps1：找不到命令 [英] (Mac) -bash: __git_ps1: command not found

问题描述

我试图在终端中改变我的命令promt。我不断收到错误信息：

-bash：__git_ps1：找不到命令

我已经试过了，只需将它输入到终端中即可： __ git_ps1 。我也在 .bash_profile

  if if [ -f〜/ .git-completion.bash];然后
 source〜/ .git-completion.bash 
 export PS1 ='[\W] $（__ git_ps1（％s））：'
 fi 
  

正如您可以看到/说出的那样，是的，我已经安装了自动完成功能，并且它确实很棒！ / p>



我遇到过这个问题： PS1的env变量不适用于mac ，它给出了代码



别名__git_ps1 =git branch 2> ; / dev / null | grep'*'| sed's / * \（。* \）/（\ 1）/'

所以我把它添加到我的 .bash_profile 中，希望它能改变一些东西。那么，它的确如此。它只是改变了错误输出。

以下是 .bash_profile 的补充：

  alias __git_ps1 =git branch 2> / dev / null | grep'*'| sed's / * \（。* \）/（ \1）/'
 
 if [-f〜/ .git-completion.bash];然后
 source〜/ .git-completion.bash 
 export PS1 ='[\W] $（__ git_ps1（％s））：'
 fi 
  

现在改变错误输出：



<$ c $注意：

strong>我也在源代码下面移动了别名，没有任何区别。我有 git 1.7.12.1版本

这应该是一个简单的改变。有人可以帮我吗？

否，我绝对不想自己定义__git_ps1，只是试图看看它是否会被识别。是的，我已经安装了 .git-completion.bash 文件。以下是我在机器上完成自动完成的过程。

  cd〜
 curl -OL https://github.com /git/git/raw/master/contrib/completion/git-completion.bash 
 mv〜/ git.completion.bash〜/ .git-completion.bash 
  

A ls -la 然后列出 .git-completion.bash file。

编辑10/13/12 - 由 Mark Longair解决（下）

以下代码在 .bash_profile 中适用于我，而另一些则不适用于...

  if [-f〜/ .git-prompt.sh];然后
 source〜/ .git-prompt.sh 
 export PS1 ='Geoff [\W] $（__ git_ps1（％s））：'
 fi 
  

解决方案

你已经安装了 git-completion .bash from master - 在git的开发历史中，这是在将 __ git_ps1 函数从完成功能转换为新文件（ git-prompt.sh ）。引入此更改的提交（解释原因）为 af31a456 。

我仍然会建议您只输入 git-completion.bash （或 git-但是，如果由于某种原因，您仍希望通过使用此功能来使用此功能，请使用以下命令：

master 单独下载的脚本，您应该同样下载 git-prompt.sh ：

  curl -o〜/ .git-prompt.sh \ 
 https://raw.githubusercontent.com/git/git/master/contrib /completion/git-prompt.sh 
  

...并将以下行添加到〜/ .bash_profile ：

  source〜/ .git-prompt.sh 
  

然后您的 PS1 变量包含 __ git_ps1'％s'应该可以正常工作。

I'm trying to change my command promt in terminal. I keep getting the error:

-bash: __git_ps1: command not found

I've tried it just by typing it into the terminal as is: __git_ps1. I've also tried it out in the .bash_profile

if [ -f ~/.git-completion.bash ]; then
  source ~/.git-completion.bash
  export PS1='[\W]$(__git_ps1 "(%s)"): '
fi

As you might be able to see/tell, yes, I do have the auto-completion installed and it does work great!

I came across this question: " PS1 env variable does not work on mac " which gives the code

alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \(.*\)/(\1)/'"

So I add it to my .bash_profile hoping that it will change something. Well, it did. It just changed the error output.

Here's the .bash_profile with the addition:

alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \(.*\)/(\1)/'"

if [ -f ~/.git-completion.bash ]; then
  source ~/.git-completion.bash
  export PS1='[\W]$(__git_ps1 "(%s)"): '
fi

And now here's the changed error output:

sed: (%s): No such file or directory

Note: I've also moved the alias below the source with no difference. I have git version 1.7.12.1

This should be a simple change. Can someone please help me?

Edit 10/13/12

No, I definitely do not want to define __git_ps1 myself but was just trying to see if it would be recognized by doing so. Yes, I have the .git-completion.bash file installed. Here's how I got auto completion on my machine.

cd ~
curl -OL https://github.com/git/git/raw/master/contrib/completion/git-completion.bash
mv ~/git.completion.bash ~/.git-completion.bash

A ls -la then lists the .git-completion.bash file.

Edit 10/13/12 - Solved by Mark Longair (below)

The following code worked for me in the .bash_profile while others did not...

if [ -f ~/.git-prompt.sh ]; then
  source ~/.git-prompt.sh
  export PS1='Geoff[\W]$(__git_ps1 "(%s)"): '
fi

解决方案

You've installed the version of git-completion.bash from master - in git's development history this is after a commit that split out the __git_ps1 function from the completion functionality into a new file (git-prompt.sh). The commit that introduced this change, which explains the rationale, is af31a456.

I would still suggest that you just source the version of git-completion.bash (or git-prompt.sh) that is bundled with your installation of git.

However, if for some reason you still want to use this functionality by using scripts separately downloaded from master, you should download git-prompt.sh similarly:

curl -o ~/.git-prompt.sh \
    https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

... and add the following line to your ~/.bash_profile:

source ~/.git-prompt.sh

Then your PS1 variable that includes __git_ps1 '%s' should work fine.
