Question

我已经编写了一个Azure Funciton API（使用python运行时）来自动化git checkin流程（在gitPython中使用）来完成我们正在做的一些工作。它在我的本地环境下工作正常。但是，当我尝试将其发布到azure函数时，API失败。

 ---> 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依赖于导入了Azure函数的系统上的“ git”可执行文件。

我的问题是：如何使用App服务计划在Azure函数上安装git。通常，如果我们需要功能应用程序安装和使用任何其他软件包，那么如何在azure函数中进行安装。

作为一种解决方法，我在导入git之前使用os.system（）安装git二进制文件。

我认为这是使用custom containers with functions的一个很好的例子。由于将要构建容器，因此可以确保安装所有外部依赖项。

另一种选择是将git可执行文件作为function package的一部分发布，并将GIT_PYTHON_GIT_EXECUTABLE应用设置设置为%HOME%\site\wwwroot\<path-to-git-in-your-package>（Windows）或$HOME/site/wwwroot/<path-to-git-in-your-package> （Linux）
