一、 适用于单虚拟环境的情况: :
pip freeze > requirements.txt
为什么只适用于单虚拟环境?因为这种方式,会将环境中的依赖包全都加入,如果使用的全局环境,则下载的所有包都会在里面,不管是不时当前项目依赖的。
二、 使用 pipreqs
github地址为: https://github.com/bndr/pipreqs
安装
pip install pipreqs
在目录生成

--debug Print debug information
--ignore <dirs>... Ignore extra directories
--encoding <charset> Use encoding parameter for file open
--savepath <file> Save the list of requirements in the given file
--print Output the list of requirements in the standard output
