pipreqs python3 不兼容问题解决

这里面可能会报几个错误：
 
1. 如果报错信息是：
如果提示“UnicodeDecodeError: 'gbk' codec can't decode ”的错误，需要指定字符集 --encoding=utf8

pipreqs ./ --encoding=utf8
 
 2. 出现诸如：

Traceback (most recent call last):

  File "c:\anaconda\envs\py37\lib\runpy.py", line 193, in _run_module_as_main

    "__main__", mod_spec)

SyntaxError: invalid syntax

明显的python2的语法报错，这时很可能是你的项目中有python2语法的py文件，可以使用
--ignore <dirs> ...忽略额外的目录
 
参数解决。
