Traceback (most recent call last):

    raise ImportError(err)
ImportError: Bad git executable.
The git executable must be specified in one of the following ways:
    - be included in your $PATH
    - be set via $GIT_PYTHON_GIT_EXECUTABLE
    - explicitly set via git.refresh()
 
All git commands will error until this is rectified.
 
This initial message can be silenced or aggravated in the future by setting the
$GIT_PYTHON_REFRESH environment variable. Use one of the following values:
    - quiet|q|silence|s|silent|none|n|0: for no message or exception
    - warn|w|warning|log|l|1: for a warning message (logged at level CRITICAL, displayed by default)
    - error|e|exception|raise|r|2: for a raised exception
 
Example:
    export GIT_PYTHON_REFRESH=quiet
 
 
The above exception was the direct cause of the following exception:

您遇到的问题是Python Git库无法找到或正确识别您的Git可执行文件。为了解决这个问题，请按照以下步骤操作：

1. 安装Git： 确保已在您的系统上安装了Git。如果没有，请访问Git官网下载并安装适用于您操作系统的Git版本。

2. 添加Git到环境变量： 在安装过程中，确保选择将Git添加到系统PATH环境变量的选项。如果已经安装但未添加到PATH，手动将其添加到系统环境变量中：

   • Windows：右键点击“此电脑”-> 属性 -> 高级系统设置 -> 环境变量 -> 在系统变量中找到Path，编辑并添加Git的安装路径（例如 C:\Program Files\Git\bin）。

3. 验证Git是否已成功添加到PATH： 打开一个新的命令行窗口（CMD），输入 git --version，如果显示Git版本信息，则说明Git已成功添加到PATH。

4. 重新运行PyCharm项目： 关闭并重新打开PyCharm，然后尝试再次运行您的项目。现在Python应该能够找到并使用Git。

5. 如果问题依然存在： 您可以在代码中指定Git的路径，通过在运行脚本之前设置环境变量的方式实现：

   import os
   os.environ['GIT_PYTHON_GIT_EXECUTABLE'] = 'C:/Program Files/Git/bin/git.exe'  # 替换为您的实际Git可执行文件路径
   

完成上述步骤后，理论上您的问题应当得到解决，程序可以顺利调用Git进行相关操作。
