只有在项目中某处实际导入的Python包，即我的项目需要它们吗？

pip freeze

会列出我系统中安装的所有软件包，但我只需要那些项目使用的软件包。

Answer 1

手动解决方案可能

使用grep

查找包

grep -r import ./*/*[.py] > j.t

使用python

迭代j.t中的所有行

fromIndex = line.find('from')
importIndex = line.find('import')
if fromIndex != -1:
    return = line[fromIndex + 5 : importIndex - 1][5:]
else:
    return = line[importIndex + 7:]

删除所有重复项

在虚拟环境中冻结pip以查找版本号

Pip冻结虚拟环境以找到其他版本号

Pip冻结实际导入的包
