我想把Monaco Editor的版本升级到v0.31.1,我做了npm install monaco-editor@0.31.1
,sudo 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;
}

按热度按时间qxgroojn1#
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: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:集成巴别塔可以通过
babel-loader
完成,参见说明here。rqqzpn5f2#
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
然后,
npm run release
,并等待它完成你得到文件夹
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-editor
和npm 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。
对不起,我的英语不好。

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。9rygscc14#
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: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。
