Echarts之导入小问题（0629）

最近学习黑马pink老师开始的Echart课程，发现跟着他学到导入echarts.min.js，导入之后再去添加配置项和数据，修改配置项和数据中的Xaxis的刻度的字体颜色时，就会导致柱形图不显示，一开始找不到解决办法，也可能是我使用了* pnpm install echarts安装的缘故，后面我发现在我添加color*属性时，.js文件中会生成一个导入的语句，如下：
在这里插入图片描述
后面我发现，只要注释掉这个语句，就可以显示柱形图了，但是具体是啥问题还是不清楚。希望知道的小伙伴可以留言讨论一下。

实现的效果是这样的，简直超酷在这里插入图片描述
