#换了电脑重装了环境，发现Django的项目起不来，折腾了好久，才看到网上一帖子，做下记录。
报错大概如下：
#python manage.py runserver
Traceback (most recent call last):

return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xca in position 367: invalid continuation byte
解决的办法：
原本这一行的代码是：
str_value = force_bytes(new_environ[key], encoding=encoding)
将其修改为：
str_value = force_bytes(new_environ[key], encoding=‘utf-8’)
保存这个文件。然后重新在cmd的界面里面执行python manage.py runserver就可以执行成功了。
