首先使用npm或者其他包管理工具安装依赖插件：

npm install monaco-editor --save
npm install monaco-editor-nls --save
npm install monaco-editor-webpack-plugin --save
npm install monaco-editor-esm-webpack-plugin --save-dev

如果右键菜单汉化一部分失败，首先去项目下看node_modules/monaco-editor-nls/locale/zh-hans中搜vs/editor/contrib/format/看一下是否有路径有brower字段，再去对应的node_modules/monaco-editor/esm/vs/editor/contrib/format/formatActions看是否有brower文件夹

1. 如果有：那么安装monaco-editor-nls最新版本
2. 没有：安装monaco-editor-nls2.0版本

npm install monaco-editor-nls@^2.0.0 --save

webpack.config.js 添加配置：

const MonacoWebpackPlugin = require('monaco-editor-esm-webpack-plugin');module.exports = {configureWebpack: {module: {rules: [{test: /\.js/,enforce: 'pre',include: /node_modules[\\\/]monaco-editor[\\\/]esm/,use: MonacoWebpackPlugin.loader}]},plugins: [new MonacoWebpackPlugin()]}
}

此处需要引入monaco-editor-esm-webpack-plugin，引入monaco-editor-webpack-plugin无法汉化成功 设置语言包

// 汉化 monaco
import { setLocaleData } from "monaco-editor-nls"
import zh_CN from "monaco-editor-nls/locale/zh-hans.json"
setLocaleData(zh_CN)
//先汉化语言，再加载monaco才能汉化成功，使用import方式无法汉化
//需要使用require方式引入monaco-editor
//import * as monaco from 'monaco-editor' 
const monaco = require("monaco-editor/esm/vs/editor/editor.api"); 
// import * as monaco from 'monaco-editor/esm/vs/editor/editor.api';
import languages from "./language";
