刚创建项目 django manage.py runserver 报错UnicodeEncodeError：'mbcs'

Question

win10系统，python 3.5.2， djang 1.10.3
刚刚创建django项目

C:\Users\JD\Desktop\firstsite>python manage.py runserver
Traceback (most recent call last):

UnicodeEncodeError: 'mbcs' codec can't encode characters in position 0--1: invalid character

网上没有搜出成功又可解决我的问题的办法。
但有别人成功却不能解决我的：

http://stackoverflow.com/ques... 或者 https://segmentfault.com/q/10...
在~Python35\lib\site-packages\django\utils\autoreload.py中添加

new_environ['PATH']=os.path.abspath(new_environ['PATH'].replace('\u202a', ''))

也可尝试添加

new_environ['PATH'] = os.path.abspath(new_environ['PATH'].encode('ascii', 'replace'))

但这两种方法都不能解决的问题。

希望有经验的同学能够看到我的问题并好心解答
谢谢

嗯根据题主的方法成功解决了……不过我是另一个环境变量，也是带u202，有一次做计组实验添加了这个变量。 我真的很想吐槽windows这个坑爹的设定，从属性->安全 这个地方复制文件路径的时候，总是会在前面自动添加一个u202，然后编程使用的时候各种编码错误，烦得要死，每次辛辛苦苦找了半天发现都是这个问题。
