vue2-editor Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '_c')

根据提供的引用内容，报错"Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'comcode')"和"Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '_c')"可能是由于在使用`monaco.editor.create`方法时，没有正确获取到DOM节点或者DOM节点未正确绑定ref导致的。

解决办法是检查一下DOM元素上绑定的ref的拼写是否与函数中的一致，并确保在Vue2中使用`this.$refs.xxx`来获取DOM元素，而在Vue3中需要在setup函数中声明一个变量并返回出去，并在DOM元素上以该变量名绑定ref。此外，在获取DOM节点的时机上，如果使用的是Vue3，则需要使用`nextTick`来确保在DOM渲染完成后再获取DOM节点。

因此，您可以检查一下代码中DOM元素的ref绑定是否正确，并根据您使用的是Vue2还是Vue3来确定正确的获取DOM节点的方法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
