我收到错误:
22 个错误有未显示的详细信息。 编译失败。 webpack < 5 默认情况下用于包含 Node.js 核心模块的 Polyfill。 这已不再是这种情况。验证您是否需要此模块并为其配置一个polyfill。
找不到模块:错误:无法解析“C:\Users\joshm\Downloads\New 文件夹 (14)\myapp\node_modules\body-parser\lib”中的“zlib” 重大更改:webpack < 5 默认情况下包含 Node.js 核心模块的 Polyfill。 这已不再是这种情况。验证您是否需要此模块并为其配置一个polyfill。
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "zlib": require.resolve("browserify-zlib") }'
- install 'browserify-zlib'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "zlib": false }

最佳答案
我也有同样的问题。这个解决方案将帮助您:
- npm 我 Node -polyfill-webpack-plugin
- 将此代码写入vue.config.js
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');
module.exports = {
configureWebpack: {
plugins: [new NodePolyfillPlugin()]
}
};
