python項(xiàng)目依賴庫(kù)生成requirements.txt文件
第一種：pip freeze > requirements.txt
第二種：pipreqs 項(xiàng)目根目錄（不能有中文）--encoding=utf8
requirements已存在： pipreqs 項(xiàng)目根目錄 --encoding=utf8 --force
第一種：pip freeze > requirements.txt
步驟：
cd 到你的項(xiàng)目根目錄
-
執(zhí)行：pip freeze > requirements.txt
C:\Users\dyunren>i: I:\>cd I:\python20\softwaredate\py_basics
缺點(diǎn)：`你本機(jī)python環(huán)境所有依賴都會(huì)寫到 requirements.txt文件當(dāng)中。
如圖展示：

第二種：pipreqs
pipreqs的安裝：
pip install pipreqs
查看版本：
pip show pipreqs 或 pipreqs --version

使用：pipreqs python項(xiàng)目根目錄
C:\Users\dyunren>i:
I:\>cd I:\python20\softwaredate\py_basics
I:\python20\softwaredate\py_basics>pipreqs
