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'
  ]

})

我的应用昨天也抛出了同样的错误。我花了几个小时在SO上阅读问题/答案，并尝试了一些。对我有用的是:

https://github.com/ChainSafe/web3.js#troubleshooting-and-known-issues

错误:[webpack < 5用于默认包含node.js核心模块的腻子。

现在情况已经不同了。验证你是否需要这个模块，并为它配置一个填充。

答: Node_modules > react-scripts > config > webpack.config.js

在webpack.config.js文件中添加:

resolve: {
      fallback: { 
        "http": require.resolve("stream-http") ,
         "path": require.resolve("path-browserify") 
        },
}

当从webpack v4升级到v5时，我也得到了这些错误。 通过对webpack.config.js进行以下更改来解决

添加的决心。回退财产

删除节点属性

{
resolve: {
  modules: [...],
  fallback: {
    "fs": false,
    "tls": false,
    "net": false,
    "path": false,
    "zlib": false,
    "http": false,
    "https": false,
    "stream": false,
    "crypto": false,
    "crypto-browserify": require.resolve('crypto-browserify'), //if you want to use this module also don't forget npm i crypto-browserify 
  } 
},
entry: [...],
output: {...},
module: {
  rules: [...]
},
plugins: [...],
optimization: {
  minimizer: [...],
},
// node: {
//   fs: 'empty',
//   net: 'empty',
//   tls: 'empty'
// },
}

从v4升级到v5 => https://webpack.js.org/migrate/5/#clean-up-configuration

我尝试了这个https://stackoverflow.com/a/71803628/15658978解决方案，它解决了我的问题。

简单地运行以下2个命令

npm uninstall react-scripts
npm install react-scripts@4.0.3

你想用在

const nodeExternals = require('webpack-node-externals');

在webpack.config.js中添加

target: "node",
devtool: "source-map",
externals: [nodeExternals()],
