A電腦寫的python指令碼，現在要放到B電腦上去執行，遇到的第一個問題是如何搭建一個和a一模一樣的環境：解決相關依賴

原部落格：https://www.aliyun.com/jiaocheng/517065.html

如下有寫好的成品指令碼，執行即可：如果有用點個贊！！！

（1）使用方法 A電腦開啟cmd 執行： python SolvePythonDependency.py down

 生成  Dependency.zip 檔案

（2）將SolvePythonDependency.py指令碼 和Dependency.zip拷到 B電腦的目錄下雙擊執行

如果有用點個贊！！！

成品指令碼，複製儲存為SolvePythonDependency.py
