太秀了吧，话说这个vModelText会监听所有的``? 在子组件内也会监听父组件的变化 [SFC](https://sfc.vuejs.org/#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)

> 但是在使用 ref 时，不能这样子声明，会报错，正确的声明方式应该是使用 来包裹类型定义，紧跟在 ref API 之后： 感觉这里容易引起歧义，确实有报错，但是是因为此时变量类型为Ref对象，而非简单的数据类型(string or number...)。这样说容易理解成不支持类型写在变量后的语法🤔

@Norgerman 我也遇到这个问题了，我是在安装@types/d3的时候，弄了好久才发现是cnpm的包有问题。。请问这个问题你是怎么解决的？

@Norgerman 谢谢，我换成淘宝的源了，但是感觉不如cnpm速度快，是这样吗？


@ireade ok, appreciate it

@ireade good job, but still something weird, the compatibility is different between `caniuse` and your image. here is caniuse result:  as you can see the chrome have different result.....

空白节点并非``这类的“空节点”，是HTML代码中空格、换行符 https://codepen.io/justforuse/pen/rNxxzLW 查看控制台输出

I think you are using Mathjax@3, for Mathjax@2, I found it should be like: ``` 'HTML-CSS': { showMathMenu: true }, ```

You mean that your formula includes `(` and `)`， but dont want to render them as mathjax formula, just print what it is?
