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。

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'
]
})

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。
我在create-react-app中遇到了这个问题
"react": "^17.0.2",
"react-dom": "^17.0.2",
"react-scripts": "5.0.0",
"web-vitals": "^2.1.2"
我通过将react-scripts更改为4.0.3版本来解决这个问题。
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
所有其他答案都遗漏了一个重要的部分:如何不填充节点核心模块。 如果错误来自你的依赖项的依赖项中的某个模块,而你实际上并不需要,你可以完全忽略它。 在这种情况下,最简单的解决方法是添加到包中。Json这些行:
"browser": {
"fs": false,
"path": false,
"os": false
}
如果需要忽略其他核心节点模块,也可以这样做。
这种方法适用于默认情况下实际webpack配置不能直接访问的框架(比如Angular)。
在寻找不同的错误时,我已经找到了这个解决方案。

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。
