vue-codemirror 最全踩坑之路

1. npm i vue-codemirror --save-D

2. 在组件中使用

<style>
.CodeMirror-scroll {
  overflow: scroll !important;
  margin-bottom: 0;
  margin-right: 0;
  padding-bottom: 0;
  height: 100%;
  outline: none;
  position: relative;
  border: 1px solid #dddddd;

</style>
<style lang="less" scoped>
.code-mirror{

  text-align: left;
}
</style>

• javascript 黑色风格，效果图如下：

        

• mysql 淡黄色风格
  
  将 theme 换成 'solarized light' , 然后将 mode 改成 'text/x-mysql'
  
  
•  白色主题风格
  
  将 theme 换成 'base16-light' 就行
