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 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/
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()
]
}
你想用在
const nodeExternals = require('webpack-node-externals');
在webpack.config.js中添加
target: "node",
devtool: "source-map",
externals: [nodeExternals()],

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。
当我重新安装节点模块时,我的webpack当前版本是5.38.1,我已经修复了这个问题 安装后,你必须更新你的webpack.config.js resolve{} with 回退:{"fs": false, "path": require.resolve("path-browserify")}而不使用"fs": false它显示错误,即:模块未找到:错误:无法解析'fs'在'/YOUR DIRECTORY…' 所以别忘了加上它;与其他东西看起来像:
module.exports = {
...
resolve: {
extensions: [".js", ".jsx", ".json", ".ts", ".tsx"],// other stuff
fallback: {
"fs": false,
"path": require.resolve("path-browserify")
}
},
};
如果你的webpack.config.js文件中存在node属性,删除它
