嗨，我对python pipreqs有一些意见。它总是告诉我用法，而不是创建正确的文件。

Question

正如您所看到的，我使用了正确的命令，它不断地告诉我用法，而不是为我创建正确的文件。

在这里输入图像描述

(WebScraping) G:\>pipreqs G:\PY CODE\WebScraping
Usage:
    pipreqs [options] [<path>]

如果我只是随机输入路径文件，它会告诉我，文件不存在。

(WebScraping) G:\>pipreqs s
Traceback (most recent call last):
File "D:\anaconda\envs\WebScraping\lib\runpy.py", line 196, in _run_module_as_main
return _run_code(code, main_globals, None,
File "D:\anaconda\envs\WebScraping\lib\runpy.py", line 86, in _run_code
exec(code, run_globals)
File "D:\anaconda\envs\WebScraping\Scripts\pipreqs.exe\__main__.py", line 7, in <module>
File "D:\anaconda\envs\WebScraping\lib\site-packages\pipreqs\pipreqs.py", line 488, in main
init(args)
File "D:\anaconda\envs\WebScraping\lib\site-packages\pipreqs\pipreqs.py", line 478, in init
generate_requirements_file(path, imports, symbol)
File "D:\anaconda\envs\WebScraping\lib\site-packages\pipreqs\pipreqs.py", line 157, in generate_requirements_file
with _open(path, "w") as out_file:
File "D:\anaconda\envs\WebScraping\lib\contextlib.py", line 135, in __enter__
return next(self.gen)
File "D:\anaconda\envs\WebScraping\lib\site-packages\pipreqs\pipreqs.py", line 81, in _open
file = open(filename, mode)
FileNotFoundError: [Errno 2] No such file or directory: 's\\requirements.txt'

当我将cmd中的主机路径cd到文档路径而不按pipreq顺序给出参数时，我最终解决了这个问题：

(WebScraping) G:\PY CODE\WebScraping>pipreqs --encoding=utf8
INFO: Successfully saved requirements file in G:\PY CODE\WebScraping\requirements.txt

但是我怎样才能像其他人一样使用普通的命令: G:\PY代码\WebScraping--这一直困扰着我，我想知道有什么东西

Answer 1

尝试添加引号：

pipreqs "G:\PY CODE\WebScraping"
