Question

我正在尝试将monaco编辑器集成到现有的react应用程序中。我按照（react-monaco-editor）的安装步骤进行操作，但是没有得到突出显示或自动完成打字稿的语法，这与FAQ一致，就好像我没有设置monaco-editor-webpack-plugin一样。

我已经设置了插件。我可以看到monaco-editor-webpack-plugin沿着我的app.js拖放文件，所以我认为它可以正常工作：

似乎我的问题是react-monaco-editor试图从错误的位置提取这些文件。如果我加载页面并打开“网络”标签，则可以看到以下内容：

有两个问题：

1-路径是我系统上的完整路径，但应该是相对路径-例如

http://127.0.0.1/dist/app/secured/49.js

2-“安全”和“ 49.js”（secured49.js）之间以及其他数字文件之间都没有斜杠，但是editor.worker.js带有斜杠（怪异）。

所以我希望回答的问题是-react-monaco-editor如何确定它将从中提取这些文件的路径，并且有什么方法可以影响该路径？

任何帮助或建议将不胜感激！下面的一些代码片段对您有所帮助。

Answer 1

事实证明这是由于我的webpack配置的输出部分中的publicPath错误导致的问题。

对于其他遇到类似问题的人，请在webpack配置中添加publicPath，以提供Web Worker JS文件的正确位置。

Answer 2

我的情况……这在 webpack.config.js 中起到了作用

  devServer: {
    https: true,
    port: 3000,
    publicPath: "/dist/"
  },
  ...
  ..
  .
  plugins: [
      ...
      ..
      .
      new MonacoWebpackPlugin({
        publicPath: "/dist/"
      })
  ]
