我试了很多办法，但都没有解决。 在手动搜索后，我得到了一行代码，它自动插入到我的vs code中 从body-parser导入{json} 我移开了，节省了时间。 我希望它能帮助到一些人。 谢谢。

我的VUE解决方案

const { defineConfig } = require('@vue/cli-service')
const webpack = require('webpack');
module.exports = defineConfig({
  configureWebpack: {
    plugins: [
      new webpack.ProvidePlugin({
        Buffer: ['buffer', 'Buffer'],
      }),
      new webpack.ProvidePlugin({
          process: 'process/browser',
      })
    ],
    resolve: {
      fallback: {
        "os": require.resolve("os-browserify/browser"),
        "url": require.resolve("url/"),
        "crypto": require.resolve("crypto-browserify"),
        "https": require.resolve("https-browserify"),
        "http": require.resolve("stream-http"),
        "assert": require.resolve("assert/"),
        "stream": require.resolve("stream-browserify"),
        "buffer": require.resolve("buffer")
      }
    }
  },

  transpileDependencies: [
    'vuetify'
  ]

})

使用node-polyfill-webpack-plugin重新添加对Node.js核心模块的支持:

安装包后，将以下内容添加到webpack.config.js中:

const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")

module.exports = {
    // Other rules...
    plugins: [
        new NodePolyfillPlugin()
    ]
}

新的vue-cli升级(v5)就是这样。为了修复它(空模块的方式)，你必须这样改变vue.config.js:

configureWebpack: (config) => {
  config.resolve.fallback = {
    ...config.resolve.fallback,
    // Include here the "empty" modules
    url: false,
    util: false,
    querystring: false,
    https: false,
  };
}

看起来你已经使用了默认情况下不包含在webpack构建中的path包。对我来说，像这样扩展webpack配置有帮助:

{
  // rest of the webpack config
  resolve: {
    // ... rest of the resolve config
    fallback: {
      "path": require.resolve("path-browserify")
    }
  },
}

也可以通过npm install path-browserify——save-dev或yarn添加path-browserify——dev来安装path-browserify。

对于我(使用React => v17;React脚本=> v5;webpack => v5)，由@Letton和@Richie Bendall建议的解决方案组合与另一个附加，即包一起工作。Json中，必须添加并安装以下包。还请注意fs版本“^2.0.0”抛出一个错误，因此更改为“0.0.1-security”。

"assert": "^2.0.0", 
"https-browserify": "^1.0.0", 
"os": "^0.1.2",
"os-browserify": "^0.3.0",
"react-app-rewired": "^2.1.9",
"stream-browserify": "^3.0.0",
"stream-http": "^3.2.0",
"fs":"^0.0.1-security",
"crypto-browserify": "3.12.0",
"buffer":"^6.0.3",
"node-polyfill-webpack-plugin": "^2.0.1"

安装完这些后，执行剩下的步骤，即将config-override .js添加到根目录，并更改包中的脚本内容。从react-scripts到react-app-rewired的Json修复了这个问题。
