当我重新安装节点模块时，我的webpack当前版本是5.38.1，我已经修复了这个问题 安装后，你必须更新你的webpack.config.js resolve{} with 回退:{"fs": false， "path": require.resolve("path-browserify")}而不使用"fs": false它显示错误，即:模块未找到:错误:无法解析'fs'在'/YOUR DIRECTORY…' 所以别忘了加上它;与其他东西看起来像:

module.exports = {
   ...
   resolve: {
    extensions: [".js", ".jsx", ".json", ".ts", ".tsx"],// other stuff
    fallback: {
      "fs": false,
      "path": require.resolve("path-browserify")
    }
  },
};

如果你的webpack.config.js文件中存在node属性，删除它

我的环境是这样的:

React => v17 React脚本=> v5 Webpack => v5

要解决这个问题，请遵循下面的说明

1-安装以下软件包

yarn add fs assert https-browserify os os-browserify stream-browserify stream-http react-app-rewired

2-在项目根目录下package.json旁边创建config-coverrides.js

添加以下代码:

const webpack = require('webpack'); module.exports = function override(config, env) { config.resolve.fallback = { url: require.resolve('url'), fs: require.resolve('fs'), assert: require.resolve('assert'), crypto: require.resolve('crypto-browserify'), http: require.resolve('stream-http'), https: require.resolve('https-browserify'), os: require.resolve('os-browserify/browser'), buffer: require.resolve('buffer'), stream: require.resolve('stream-browserify'), }; config.plugins.push( new webpack.ProvidePlugin({ process: 'process/browser', Buffer: ['buffer', 'Buffer'], }), ); return config; }

3-像下面这样修改packages.js

"脚本":{ “start”:“react-app-rewired start”， “build”:“react-app-rewired build”， “test”:“react-app-rewired test” "eject": "react-app-rewired eject" }，

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。

我在create-react-app中遇到了这个问题

"react": "^17.0.2",
"react-dom": "^17.0.2",
"react-scripts": "5.0.0",
"web-vitals": "^2.1.2"

我通过将react-scripts更改为4.0.3版本来解决这个问题。

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,
  };
}

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'
  ]

})
