导入goco模块时触发SyntaxError：Python2异常捕获语法不兼容Python3

报错信息：

SyntaxError: multiple exception types must be parenthesized

错误原因：

依赖库Crypto的RSA.py文件使用了Python2的多异常捕获语法，不符合Python3的语法规范，导致导入时触发SyntaxError。

解决方案：

卸载旧的Python2版本Crypto库：
```
pip uninstall Crypto
```
安装兼容Python3的替代库pycryptodome（API与原Crypto兼容，完全支持Python3语法）：
```
pip install pycryptodome
```
（可选）更新oauth2client到适配Python3的版本，避免其他潜在兼容问题：
```
pip install --upgrade oauth2client
```
完成后重新尝试导入goco模块：
```
import goco
```
