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。

当前回答
npm install assert --save
npm install buffer --save
对于任何面临类似问题的人,只需安装缺少的模块。这些模块被报告为缺失,因为它们是node.js的一部分,但也可以通过npm单独使用。

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'
]
})
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")
}
}
};

This is no longer the case. Verify if you need this module and configure a polyfill for it.

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。
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。
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
