[Bug] Package dependency issue

[Aperjump]

Describe the bug

Under pip 18.0 python3, I encountered an error when installing one dependent package jupyter-echarts-pypkg==0.1.0. Below is my error message:

Collecting jupyter-echarts-pypkg==0.1.0 (from pyecharts==0.4.1->quantaxis==1.0.69.dev3)

    During handling of the above exception, another exception occurred:

To Reproduce

mkvirtualenv quantenv
workon quantenv
cd /path-to-quantaxis/
pip --no-cache-dir -e .

Expected behavior
The error relates to pyecharts package, and I find !this issue in pyecharts discussion.
When I upgrade my pyecharts package to 0.5.6, the bug disappears.
