Hue 编译异常：ImportError: cannot import name ‘six‘ from ‘urllib3.packages‘

个人博客地址：Hue 编译异常：ImportError: cannot import name 'six' from 'urllib3.packages' | 一张假钞的真实世界

在编译Hue的时候出现错误信息如下：

ImportError: cannot import name 'six' from 'urllib3.packages' (/usr/lib/python3/dist-packages/urllib3/packages/__init__.py)

错误原因：根据错误信息可以看到是“/usr/lib/python3/dist-packages/urllib3”这个包的问题。正确的应该是引用“build/env/lib/python3.7/site-packages/”下的包。查看”/usr/lib/python3/dist-packages/urllib3”下的包信息，发现包版本比较低。

$ ls -l /usr/lib/python3/dist-packages/
drwxr-xr-x  6 root root   4096 1月  13 17:07 urllib3
drwxr-xr-x  2 root root   4096 1月  13 17:06 urllib3-1.22.egg-info

解决方法：删除有问题的包后再试成功。

$ sudo rm -rf /usr/lib/python3/dist-packages/urllib3*

查看“build/env/lib/python3.7/site-packages/”下的urllib3包信息：

$ ls -l build/env/lib/python3.7/site-packages/|grep urllib3
drwxr-xr-x  6 zhangjc zhangjc   4096 6月  23 17:06 urllib3
