运行会出现UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 6报错

修改config/confile.py  第152行：
 ```python
       with open(conf_file) as f:
            import yaml
            return yaml.safe_load(f.read())
```
修改为：
 ```python
       with open(conf_file, encoding="utf-8") as f:
            import yaml
            return yaml.safe_load(f.read())
```
