一、根据环境中的包生成
二、利用 pipreqs 包

一、根据环境中的包生成

    pip freeze > requirements.txt

缺点显而易见, 当环境中有的包, 在项目中没有用到的时候, requirement.txt 中的包会有多余

二、利用 pipreqs 包

   pip install pipreqs

   pipreqs /your/project/path  # /your/project/path 项目的真实地址
   Traceback (most recent call last):  

    File "c:\python37\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
    File "c:\python37\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
    File "C:\Python37\Scripts\pipreqs.exe\__main__.py", line 9, in <module>
    File "c:\python37\lib\site-packages\pipreqs\pipreqs.py", line 470, in main
    init(args)
    File "c:\python37\lib\site-packages\pipreqs\pipreqs.py", line 409, in init
    follow_links=follow_links)
    File "c:\python37\lib\site-packages\pipreqs\pipreqs.py", line 122, in get_all_imports
    contents = f.read()
    UnicodeDecodeError: 'gbk' codec can't decode byte 0x9a in position 1129: illegal multibyte sequence

打开文件 c:\python37\lib\site-packages\pipreqs\pipreqs.py 122行上一行中 encoding=encoding 修改为 encoding="utf8" 重试 ```bash pipreqs /your/project/path # /your/project/path 项目的真实地址
