Python项目模块找不到路径问题

此篇仅作为工作是遇到问题的记录，不进行任何阐述

工作问题：
模块无法正确找到路径，也就是sys.path里面没有当前模块路径，所以导致导包出错，索性写个小函数，将当前项目的所有文件夹都加入sys.path模块，一劳永逸

添加到sys.path

rootpath = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
sys.path.extend([rootpath, ])

from libs.find_path import extend_path

syspath = sys.path
sys.path.extend(extend_path([rootpath, ]))
sys.path.extend(syspath)

extend_path函数

import os

PATHList = []
DirFlag = 1


def extend_path(tlist):
    """
    寻找路径函数，解决单独模块找不到路径问题
    :param tlist:  -> list of path
    :return:  -> if has dir then return dir list; else return final path list
    """
    global PATHList
    global DirFlag
    PATHList += tlist
    if DirFlag == 0:
        return PATHList
    ttlist = []
    DirFlag = 0
    for i in tlist:
        for data in os.listdir(i):
            tpath = os.path.join(i, data)
            if os.path.isdir(tpath) and '__pycache__' not in tpath and 'migrations' not in tpath:
                ttlist.append(tpath)
                DirFlag = 1
    return extend_path(ttlist)
