UnicodeDecodeError django

Question

在django项目中加载localhost：8000时出现此错误，并且在每个django项目中都是相同的情况

'utf8' codec can't decode byte 0x81 in position 501470: invalid start byte
Request Method:     GET
Request URL:    http://localhost:8/barang/
Django Version:     1.8.4
Exception Type:     UnicodeDecodeError
Exception Value:    

Exception Location:     C:\Python27\lib\codecs.py in decode, line 296
Python Executable:  C:\Python27\python.exe

我该如何解决？
