我想把Monaco Editor的版本升级到v0.31.1,我做了npm install monaco-editor@0.31.1sudo PORT=8000 HTTPS=true ./node_modules/.bin/react-app-rewired start重新编译给了我以下错误:

Failed to compile.

./node_modules/monaco-editor/esm/vs/language/html/monaco.contribution.js 154:11
Module parse failed: Unexpected token (154:11)
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
|     dispose() {
|       onLanguageListener.dispose();
>       mode?.dispose();
|       mode = void 0;
|     }

有人能帮忙吗?

编辑2:

按照@Bart的回答,我通过yarn add @babel/preset-env --dev安装了@babel/preset-env,并使用{"presets": ["@babel/preset-env"]}创建了babel.config.json,但react-app-rewired start给出了相同的错误。
然后,我意识到我确实有一个文件config-overrides.js,内容如下:

module.exports = function override (config, env) { 
    // disable chunks so the index.html won't change during development 
    config.optimization.splitChunks = {
        cacheGroups: {
            default: false,
        },
    };
    config.optimization.runtimeChunk = false;
    return config;
}

然后我添加了config.module.rules的部分,但是编译返回了相同的错误。

**此外,似乎可以使用yarn build构建项目而不会出现此错误。**但构建项目需要时间。

module.exports = function override (config, env) {
    config.module.rules = 
        [
          {
            test: /\.m?js$/,
            exclude: /(node_modules|bower_components)/,
            use: {
              loader: 'babel-loader',
              options: {
                presets: ['@babel/preset-env']
              }
            }
          }
        ]
    
    // disable chunks so the index.html won't change during development 
    config.optimization.splitChunks = {
        cacheGroups: {
            default: false,
        },
    };
    config.optimization.runtimeChunk = false;
    return config;
}

问题似乎出在可选的链接语法上(mode?.dispose();中的?.)。这也被列为Monaco变更日志中的重大更改:
生成的代码现在与ESBuild捆绑在一起,并且生成的代码利用了较新的浏览器功能,例如可选链接。这些功能应该在所有浏览器中可用,但旧的JS解析器可能无法正确解析它们,特别是Parcel v1可能在解析JS时出现问题。
correct Babel plugin可以很好的处理这个语法。一般来说,最好使用@babel/preset-env而不是单独的插件。这个预置可以同时处理几个插件。你有一个babel配置文件可以包含这个预置吗?这可以像安装@babel/preset-env作为一个开发依赖一样简单。并在项目根目录中创建一个包含以下内容的babel.config.json文件:

{
  "presets": ["@babel/preset-env"]
}

其次,这可能意味着您的Babel配置已经正常工作,但Webpack(Create React App在引擎盖下使用)忽略了node_modules中的任何内容,这通常是为了加快蒸发时间。然后,您必须找到一种方法来否决Webpack配置,以便不会跳过monaco依赖项进行蒸发。
我看到您已经在使用react-app-rewired,因此更新Webpack配置是按照他们的文档中的说明进行的:

// config-overrides.js
module.exports = function override (config, env) { 
    // disable chunks so the index.html won't change during development 
    config.optimization.splitChunks = {
        cacheGroups: {
            default: false,
        },
    };
    config.optimization.runtimeChunk = false;
    
    config.module.rules = [
      {
        test: /node_modules\/monaco-editor/,
        use: {
          loader: 'babel-loader',
          // if you include your babel config here,
          // you don’t need the `babel.config.json` file
          options: { presets: ['@babel/preset-env'] }
        }
      },
      ...config.module.rules
    ]
    return config;
}

集成巴别塔可以通过babel-loader完成,参见说明here

我在Vue项目中遇到了与您相同的问题。
也许你可以这样处理:
从GitHub下载monaco-editor的源代码
修改函数buildESM和文件monaco-editor/build/utils.js中的函数buildOneAMD
例如:将target设置为es2015

function buildESM(options) {
    build({
        entryPoints: options.entryPoints,
        bundle: true,
        target: 'es2015',
        format: 'esm',
        define: {
            AMD: 'false'
        },
        banner: {
            js: bundledFileHeader
        },
        external: options.external,
        outbase: `src/${options.base}`,
        outdir: `out/release/${options.base}/esm/`,
        plugins: [
            alias({
                'vscode-nls': path.join(__dirname, 'fillers/vscode-nls.ts')
            })
        ]
    });
}

然后,npm run release,并等待它完成

npm run release

你得到文件夹monaco-editor/release,复制文件夹release的内容并粘贴到你在项目下创建的文件夹modules/monaco-editor中。
在您的项目中,修改package.json,将monaco-editor设置为file:modules/monaco-editornpm install
一个二个一个一个
以上就是我解决这个问题的方法,如果有人找到更好的解决方法,请回复我。

我的项目也遇到了同样的问题。有一个monaco-editor-webpack-plugin可以处理这些加载器问题。但是最新版本有一些问题。所以我安装了monaco-editor-webpack-plugin@6.0.0沿着monaco-editor@0.30.1。然后你只需要把插件添加到webpack中。

const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin');

module.exports = {
  // ...
  plugins: [
    new MonacoWebpackPlugin(),
  ],
};

我们找到了两个临时解决办法:
第一个解决方案是,通过遵循此线程,在package.json中使用以下代码:

"browserslist":[
    ">0.2%",
    "not dead",
    "not op_mini all"
]

第二种解决方案是使用import * as monaco from 'monaco-editor/esm/vs/editor/editor.api'而不是import * as monaco from 'monaco-editor'
这两种解决方案都绕过了可选链接语法的错误,我们还没有找到一种直接的方法来处理babel、babel-loder、react-app-rewired等。
