警告 [Deprecation] Listener added for a synchronous 'DOMNodeInserted' DOM Mutation Event. This event type is deprecated (https://w3c.github.io/uievents/#legacy-event-types) and work is underway to remove it from this browser. Usage of this event listener will cause performance issues today, and represents a risk of future incompatibility. Consider using MutationObserver instead.
原因： node包 vue-quill-editor 引用的 quill包内部问题
处理方案
- 找到该包blots下scroll.js文件，搜索 DOMNodeInserted 找到
// Some reason fixes composition issues with character languages in Windows/Chrome, Safari
this.domNode.addEventListener('DOMNodeInserted', function() {});
2.任意选择一种替换上述代码，并保存
/* 1.
let observer = new MutationObserver(function (mutations) {
//mutations.forEach(function (mutation) {
// Обработка изменений в DOM
//console.log(mutation);
//});
});
// Настройка на отслеживание изменений в документе
let observerConfig = {childList: true, subtree: true};
observer.observe(_this.domNode, observerConfig);
*/
/* 2.
var observer = new MutationObserver(function () {});
observer.observe(_this.domNode, { childList: true });
*/
3.重新打包，直接从git上获取的包文件不支持在windows系统上打包，需要调整打包命令
"build:webpack": "webpack --config _develop/webpack.config.js & (rm dist/quill.core dist/quill.bubble dist/quill.snow || del /Q /F ".\dist\quill.core" ".\dist\quill.bubble" ".\dist\quill.snow")",
4.运行 npm run build:webpack 将重新生成dist文件，重启项目即可
补充：
1.过程中可能会发现找不到webpack.config.js文件，原因有二，其一是确实没有，去git上获取，其二是3的原因
2.npm下载bill包的依赖时会提示node版本不对，请根据提示重新按照node包。如果使用nvm下载的，则有概率没有同时下载npm，此时也根据nvm的提示去下载。
3.关于2.中的npm下载后的调整会写在我另外的记录中
