气流错误：AttributeError：模块“airflow.utils.log”没有属性“file_processor_handler”

我的本地气流即时已启动并正在运行，但现在当我运行气流网络服务器或任何其他气流命令时，我收到以下错误（带有一些回溯）：

  Unable to load the config, contains a configuration error.
  Traceback (most recent call last):
  File "/anaconda3/lib/python3.6/logging/config.py", line 382, in resolve
  found = getattr(found, frag)
  AttributeError: module 'airflow.utils.log' has no attribute 'file_processor_handler'

  During handling of the above exception, another exception occurred:

  The above exception was the direct cause of the following exception:

我尝试升级气流，但没有帮助

我刚刚遇到了与您提到的相同的问题。

即使我只是导入 pandas lib，我也会遇到这个问题。

原因是我有一些名为 email.py 的 dag 文件。与 python 内部库名称相同。冲突导致 python 停止工作。将 email.py 重命名为 email_test.py 后。 问题解决了。

你可以参考类似的问题。这是相同的问题和相同的解决方案。ImportError：无法导入 DAG 气流 https://stackoverflow.com/questions/50132985/importerror-cannot-import-dag-airflow
