之前覺得windows電腦安裝的pythonThe environment is too messy and too impure,Or temporarily need to go to another office to run quicklypython環境比較麻煩,因此了解了一下python嵌入式版本.上一期windows環境下安裝多個任意版本的python環境Teach you how to build onepythonA few basic steps for an embedded environment.String them together with a script in this issue.
My first thought is,安裝python基本環境 + 添加pythonPackage index path + 配置pip + 用pipDownload the required third-party libraries,最後運行測試.因此windowsThe script revolves around these steps.
Folder settings are similar to projects,pkg是用於安裝python環境的配置文件,src是源代碼,testis the test script storage path
5. 目錄結構：根目錄 ---
|--- pkg （python環境安裝包）
|--- src （源代碼存放路徑）
|---test (Test script storage path)
根據pycharm的習慣,The environment is generally installed in venv下面.Hence the command requiredmkdir,batThe command to script the new folder is md.We noticed that it is generally downloaded from the official websitepython Embedded packages arezip壓縮文件,So we also need to compress it with a compression script.我選擇的是winrar,Of course, in order to prevent everyone from not using this software,A judgment branch for manual decompression has also been added.
腳本如下：

pythonThe index package path is made by python*._pth文件決定的,To support indexing of third-party libraries and indexing of your own code.我們需要編寫一個pythonThe script modifies thispython*._pth文件.python腳本update-pth.py

使用get-pip.py 安裝pip,The official script has been given,沒啥好說的,Copy and download it as a script.Then download according to the project needsrequirements中的內容,pipFor details on how to use it, please refer tohttps://blog.csdn.net/immerseinstudy/article/details/124072198
echo\
echo 正在安裝pip環境...

cd %head%
echo Done
echo\
The method of running the environment is as follows,python.exe main.py.Just adding an absolute path.注意bash腳本可以通過pwd獲取當前路徑,而batThe current path of the script is stored in%cd%變量中.
echo\
echo 運行測試用例...
md "%head%\test"
"%pythonenv%\python.exe" "%head%\src\main.py"
echo 運行成功
echo\
echo 恭喜 ^_^!! 環境搭建完成~~
If necessary, I will put the complete embedded compressed package up,Because I don't know how to upload content to csdn..
