python - Airflow initdb 失败 : ImportError: No module named log.logging_mixin

Question

我在没有 root 访问权限的计算机上安装了airflow 1.7.0。所有内容都安装在/apps/dist/中，我是其所有者

冉

$ pip install apache-airflow

我取得了很多成功，直到这:

You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

所以我听取了他们的建议，升级了 pip:

$ pip install --upgrade pip
Collecting pip
  Downloading pip-9.0.3-py2.py3-none-any.whl (1.4MB)
    100% |████████████████████████████████| 1.4MB 826kB/s 
Installing collected packages: pip
  Found existing installation: pip 9.0.1
    Uninstalling pip-9.0.1:
      Successfully uninstalled pip-9.0.1
Successfully installed pip-9.0.3

然后我重新运行 pip install apache-airflow，并得到 57 行“需求已满足”。下一步:

$ airflow initdb
Traceback (most recent call last):
  File "/apps/dist/python/bin/airflow", line 17, in <module>
    from airflow import configuration
  File "/apps/dist/python/lib/python2.7/site-packages/airflow/__init__.py", line 29, in <module>
    from airflow import configuration as conf
  File "/apps/dist/python/lib/python2.7/site-packages/airflow/configuration.py", line 31, in <module>
    from airflow.utils.log.logging_mixin import LoggingMixin
ImportError: No module named log.logging_mixin

我搜索了“ImportError:没有名为 log.logging_mixin 的模块”，并得到了一堆 pip 击讨论日志记录。因此，我搜索了 ImportError: No module named "log.logging_mixin"，但基本上没有找到任何结果。

我错过了什么？

Answer 1

所以，问题在于 pip 高估了它的完成时间。

我卸载了airflow，然后重新安装了它，pip 提示/apps/dist/python/bin/airflow 的存在

再次卸载，删除/apps/dist/python/bin/airflow，重新安装，现在一切正常
