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'
  ]

})

NPM install path-browserify 然后尝试更改webpack配置以包括:

module.exports = {
    ...
    resolve: {
        alias: {
            path: require.resolve("path-browserify")
        }
    }
};

我想这里的大部分答案都能解决你的问题。然而，如果你的节点开发不需要Polyfills，那么我建议在Webpack模块配置中使用target: 'node'。这帮我解决了这个问题。

这里有一些关于答案的文档:https://webpack.js.org/concepts/targets/

Create React App刚刚发布了v5，现在实现了Webpack v5。这将完全打破许多库，其中包括web3作为必需的节点核心库腻子将会丢失。

为了快速解决这个问题，你可以在package.json中修改这个:

"react-scripts": "^5.0.0"

这个

"react-scripts": "4.0.3"

在这之后:

rm -r node_modules

rm package-lock.json

npm install

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()
    ]
}
