一.pip 版本升級造成的原因
升級過后會有 logging-0.4.9.6的在你的/Library/Python/2.7/site-packages/文件夾下的，刪除即可。
二.easy_install 的logging文件
若是前面第一步完成后還沒有解決，繼續查看下一步即可，親
logging文件也是在/Library/Python/2.7/site-packages/文件夾下
@Aarushi-Ign You shouldn't have any logging-0.4.9.6, or easy_install logging. The logging module is part of the standard library. What seems to be happening is that your 3rd-party logging module is overriding the stdlib version (that's a fault of easy_install, which puts 3rd party modules ahead of the standard library in PYTHONPATH).
Try uninstalling all 3rd party logging modules, and that should fix your issue.
這是翻牆看到的解決方案。
