Python3.7 pyecharts安装成功但是导包出现 cannot import name ‘Bar‘ 错误信息

导入包时

from pyecharts.charts import Bar

Bar 出现错误，但明明是安装了 就是无法导入

from pyecharts import Bar
 ImportError: cannot import name 'Bar' from 'pyechats ..........路径

网上解决办法其一

下面是解决办法
打开 pycharm 自带的 Terminal

先卸载之前的pyecharts 
然后在输入：pip3 install pyecharts==1.7.0 （这个可以避免新版本的新属性）
如果速度太慢，建议使用其他源
比如 pip3 install -i https://pypi.doubanio.com/simple pyecharts==1.7.0

如果还是没用，建议去看看目录下的__init__.py文件

以下是我的问题：
但不幸的是这个办法对我没有什么效果，我查了很久，还是没什么发现，后来我去目录看了下，发现/pycharts/charts/init.py竟然是空的，随后我便复制了以下代码
