本文主要介紹了pipreqs?./?--encoding=utf-8?--force?報錯問題解決,文中通過示例代碼介紹的非常詳細,對大家的學習或者工作具有一定的參考學習價值,需要的朋友們下面隨著小編來一起學習學習吧

報的編碼問題，其實不是：

解決方法:

pipreqs --ignore .venv --force

--ignore: 忽略執(zhí)行

--force : 強制覆蓋requirements.txt的內容

解決過程

1.執(zhí)行命令：

pipreqs ./ --encoding=utf-8 --force

2.報錯如下：

3.再次執(zhí)行命令：

 pipreqs ./ --encoding=iso-8859-1 --force

4.再次報錯如下：

5.解決方法：

虛擬環(huán)境依賴問題忽略.venv：執(zhí)行成功

pipreqs --ignore .venv --force
