以下の極めてシンプルなコードを実行したところ，

```

     from boxsdk import JWTAuth
    
```

urllib3関連の以下のエラーが出てしまいました。

```

    Traceback (most recent call last):
      File "C:\user\requests_toolbelt\_compat.py", line 48, in <module>

    ImportError: cannot import name 'appengine' from 'requests.packages.urllib3.contrib' (C:\user\urllib3\contrib\__init__.py)
    
    During handling of the above exception, another exception occurred:
