jenkins使用python plugin编写代码构建时报错：Caused: java.io.IOException: Cannot run program “python“

jenkins的python plugin``编写代码构建时报错：

Building in workspace D:\Jenkins\workspace\pytest项目
[pytest项目] $ python C:\Windows\TEMP\jenkins1719562851337506537.py
The system cannot find the file specified

Build step 'Execute Python script' marked build as failure
Finished: FAILURE

其中我们看到这一句：
**Caused: java.io.IOException: Cannot run program “python” (in directory “D:\Jenkins\workspace\pytest项目”): CreateProcess error=2, 系统找不到指定的文件。
at java.lang.ProcessBuilder.start(Unknown Source)

大概的意思是python程序没有添加到环境变量中，导致python程序没找到，运行失败`!!``

解决办法：把windows本地python的安装路径添加到系统变量的path中，，注意一定要是系统变量的path 如我本地的python安装路径为：C:\Users\admin\AppData\Local\Programs\Python\Python37\

添加完成后保存，并重启jenkins,再构建一遍

构建完成
