bash：git_prompt：找不到命令

Question

我遇到此烦人的git_prompt: command not found错误。我有一台新的Mac，并且尝试将旧的.bash_profile用于新的计算机。我使用了Thoughtbot's laptop配置，上次效果很好。

我正在Mac Os Sierra上运行，这是我的.bash_profile：

# Configuring Our Prompt
# ======================

  # if you install git via homebrew, or install the bash autocompletion via homebrew, you get __git_ps1 which you can use in the PS1
  # to display the git branch.  it's supposedly a bit faster and cleaner than manually parsing through sed. i dont' know if you care
  # enough to change it

  # This function is called in your prompt to output your active git branch.
  function parse_git_branch {
    git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
  }

  # This function builds your prompt. It is called below
  function prompt {
    # Define some local colors

    local   LIGHT_RED="\[\033[1;31m\]" # really understood
    local        CHAR="theAsteve  :"    local   BLUE="\[\e[0;49;34m\]"

    # ♥ ☆ - Keeping some cool ASCII Characters for reference

    # Here is where we actually export the PS1 Variable which stores the text for your prompt
    export PS1="theAsteve$  "
      PS2='> '
      PS4='+ '
    }

  # Finally call the function and our prompt is all pretty
  prompt


  export NODE_PATH="/usr/local/lib/node_modules:$NODE_PATH"

  export GIT_MERGE_AUTOEDIT='no'

    # Editors
    # Tells your shell that when a program requires various editors, use sublime.
    # The -w flag tells your shell to wait until sublime exits
    export VISUAL="vim"
    export SVN_EDITOR="vim"
    export GIT_EDITOR="vim"
    export EDITOR="vim"

    # Version
    # What version of the Flatiron School bash profile this is
  # Paths

    # The USR_PATHS variable will just store all relevant /usr paths for easier usage
    # Each path is seperate via a : and we always use absolute paths.

    # A bit about the /usr directory
    # The /usr directory is a convention from linux that creates a common place to put
    # files and executables that the entire system needs access too. It tries to be user
    # independent, so whichever user is logged in should have permissions to the /usr directory.
    # We call that /usr/local. Within /usr/local, there is a bin directory for actually
    # storing the binaries (programs) that our system would want.
    # Also, Homebrew adopts this convetion so things installed via Homebrew
    # get symlinked into /usr/local
    export USR_PATHS="/usr/local:/usr/local/bin:/usr/local/sbin:/usr/bin"

    # Hint: You can interpolate a variable into a string by using the $VARIABLE notation as below.

    # We build our final PATH by combining the variables defined above
    # along with any previous values in the PATH variable.

    # Our PATH variable is special and very important. Whenever we type a command into our shell,
    # it will try to find that command within a directory that is defined in our PATH.
    # Read http://blog.seldomatt.com/blog/2012/10/08/bash-and-the-one-true-path/ for more on that.
    export PATH="$USR_PATHS:$PATH"

    # If you go into your shell and type: echo $PATH you will see the output of your current path.
    # For example, mine is:
    # /Users/avi/.rvm/gems/ruby-1.9.3-p392/bin:/Users/avi/.rvm/gems/ruby-1.9.3-p392@global/bin:/Users/avi/.rvm/rubies/ruby-1.9.3-p392/bin:/Users/avi/.rvm/bin:/usr/local:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/local/mysql/bin:/usr/local/share/python:/bin:/usr/sbin:/sbin:

我尝试了其他一些关于同一问题的帖子。我尝试遍历以下代码，但未成功。 -bash: __git_ps1: command not found

我已经使用此功能多年，并且在添加到〜/ .bashrc的底部时可以使用

设置和配置源：https://github.com/jimeh/git-aware-prompt

function parse_git_branch () {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
YELLOW="\[\033[0;33m\]"
GREEN="\[\033[0;32m\]"
NO_COLOR="\[\033[0m\]"
PS1="$GREEN\u@\h$NO_COLOR:\w$YELLOW\$(parse_git_branch)$NO_COLOR\$ "

是这样的：

user@server:~/dev/project (Some-Branch-Feature)$

您将不得不随心所欲地玩弄它，但希望它能带您到某个地方。
