ImportError:无法从'oauthlib.common‘导入名称'bytes_type’

Question

我正在将airflow从1.10.5更新到1.10.10。在使用google OAuth时，我在webserver中遇到以下错误

Traceback (most recent call last):

    from oauthlib.common import to_unicode, bytes_type
ImportError: cannot import name 'bytes_type' from 'oauthlib.common' (/home/airflow/.local/lib/python3.7/site-packages/oauthlib/common.py)

此错误是由于依赖项不匹配造成的。Airflow 1.10.10正在安装oauthlib==3.1.0和Flask-OAuthlib==0.9.5，而在3.1.0 version of oauthlib中，没有bytes_type，而Flash-OAuthlib希望它在那里。

考虑到lepture已经归档了flask-oauthlib并创建了authlib，我在lepture的airflow中看到了关于此更改的PR https://github.com/apache/airflow/pull/6140/files，但它没有被机器人合并并标记为陈旧

有人在Airflow 1.10.10中遇到过这个问题吗？我已经通过更改requirement.txt中的oauthlib version to 2.1.0修复了此问题

我们遇到了同样的问题，并通过强制升级flask_oauthlib到0.9.6来暂时修复它：(当我们等待airflow修复其依赖项时)

pip install flask_oauthlib==0.9.6
