我编写了一个使用Python运行时的Azure Funciton API，用于自动化一些工作的git checkin过程(使用gitPython)。在我的本地环境中它可以正常工作。然而，当我尝试将其发布到Azure Function时，API失败了。
---> Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcException: Result: Failure
Exception: ImportError: Failed to initialize: 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 warning 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|none|n|0: for no warning or exception
- warn|w|warning|1: for a printed warning
- error|e|raise|r|2: for a raised exception
Example:
export GIT_PYTHON_REFRESH=quiet

原因是GitPython依赖于导入Azure函数的系统上的“git”可执行文件。
我的问题是：如何在使用App服务计划的Azure函数上安装git。一般来说，如果我们需要安装和使用函数应用程序的任何附加包，如何在Azure函数中实现它。
作为解决方法，我正在使用os.system()在导入git之前安装git二进制文件。
