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,
  };
}

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。

如果你使用Twilio:

Twilio模块不是用于客户端JavaScript的，这就是它在Angular应用中失败的原因。Twilio使用您的帐户SID和您的认证令牌，在客户端使用代表风险; 所以最好是在服务器端使用它并使用API。

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。

我喜欢把事情简单化，在这里之前不需要运行npm run-script eject，所以我降级回react-scripts@4.0.3而不是5.0.0 到目前为止，Webpack仍然没有解决这个问题

可悲的是，因为这包括一堆退役的包裹。

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
