python專案打包時，需要將虛擬環境與python自身安裝路徑下的lib包整合在一起，將如下內容儲存為packvenv.s**件，修改python_path（python的安裝路徑）以及venv_path（虛擬環境的全路徑）為自己的目錄，然後給檔案新增執行許可權：chmod +x packvenv.sh，./packvenv.sh執行即可

Python虛擬環境專案例項
這裡想象一下需求，寫乙個專案使用的一系列1.0版本的外掛程式，現在要新寫乙個專案，需要用這些外掛程式的2.0版本，該怎麼辦？都更新成2.0版本？這樣之前的專案都沒法維護了 這時我們需要乙個虛擬環境，python就支援這樣乙個外掛程式，virtualenv 下面來安裝一下 1.pip3 install...
建立python虛擬環境並打包python檔案
當需要為乙個離線環境部署python應用時，離線環境可能缺少各種python環境，有docker的話可以用docker，沒有docker可以用pyinstaller打包成二進位制檔案。pyinstaller會打包當前所有用pip安裝的包，所以建議在虛擬環境中打包python應用。安裝virtuale...
