运行官方demo的时候报错
>>> from pyecharts.charts import Bar
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name Bar
解决办法:源码安装
git clone https://github.com/pyecharts/pyecharts.git
cd pyecharts
pip install -r requirements.txt
python setup.py install
编译完成之后需将pyecharts文件夹复制到python安装目录的site-packages下
