Centos 系统  试过其它方法，不管用，最终通过改配置文件解决了

找到my.cnf文件

在my.cnf文件里面配置如下：

character-set-server=utf8

collation-server=utf8_general_ci

重启mysql

service mysqld restart

删除数据库重新执行

  谢谢！删除的是测试用例的数据库吗

django.db.utils.InternalError: (1366, "Incorrect string value: '\\xE7\\x94\\xA8\\xE6\\x88\\xB7' for column `test_zanhu`.`auth_permission`.`name` at row 1")

这是给某个字段赋值错误了，类型与数据库字段里定义的不匹配。你检查下测试用例里写的值，还有问题的话截图一下代码吧~

  我检查了一下，是运行测试时生成的临时数据库的默认编码不是utf8，按照这个文章在base.py添加# DATABASES = {
  #     'default':
  #     {
  #         'ENGINE': 'django.db.backends.mysql',
  #         'TEST': {
  #             'CHARSET' : 'utf8',
  #             'COLLATION':'utf8_general_ci'
  #         }
  #     },
  # }设置,没有起作用，最终改了数据库的配置文件，增加[mysqld]
  character_set_server=utf8并重启，测试就能走下去了

  棒极了！
