Webpack 5不再对节点核心模块进行自动填充。 请问怎么修?
break CHANGE:默认情况下,webpack < 5用于为node.js核心模块包含polyfills。 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。

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,
};
}
其他回答
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
