Question

我安装了Laravel并运行npm run watch命令，它返回：

ERROR in ./node_modules/destroy/index.js
Module not found: Error: Can't resolve 'fs' in 'C:\xampp\htdocs\checknpm\node_modules\destroy'

ERROR in ./node_modules/express/lib/request.js
Module not found: Error: Can't resolve 'net' in 'C:\xampp\htdocs\checknpm\node_modules\express\lib'

ERROR in ./node_modules/engine.io/lib/server.js
Module not found: Error: Can't resolve 'uws' in 'C:\xampp\htdocs\checknpm\node_modules\engine.io\lib'

然后我在laravel webpack.mix.js中进行一些配置：

mix.webpackConfig({
    target: "node",
});

然后重新调整：

WARNING in ./node_modules/socket.io/lib/index.js
113:11-32 Critical dependency: the request of a dependency is an expression

WARNING in ./node_modules/node-gyp-build/index.js
13:9-32 Critical dependency: the request of a dependency is an expression

WARNING in ./node_modules/node-gyp-build/index.js
20:15-54 Critical dependency: the request of a dependency is an expression

WARNING in ./node_modules/express/lib/view.js
81:13-25 Critical dependency: the request of a dependency is an expression

ERROR in ./node_modules/engine.io/lib/server.js
Module not found: Error: Can't resolve 'uws' in 'C:\xampp\htdocs\checknpm\node_modules\engine.io\lib'

最后我添加了：

mix.webpackConfig({
    target: "node",
    externals: {
        uws: "uws",
        ws: "ws",
    },
});

当我运行npm run watch时，它返回：

WARNING in ./node_modules/socket.io/lib/index.js
113:11-32 Critical dependency: the request of a dependency is an expression
 @ ./node_modules/socket.io/lib/index.js
 @ ./resources/js/bootstrap.js
 @ ./resources/js/app.js
 @ multi ./resources/js/app.js ./resources/sass/app.scss

WARNING in ./node_modules/express/lib/view.js
81:13-25 Critical dependency: the request of a dependency is an expression
 @ ./node_modules/express/lib/view.js

 @ ./node_modules/express/index.js
 @ ./resources/js/bootstrap.js
 @ ./resources/js/app.js
 @ multi ./resources/js/app.js ./resources/sass/app.scss

我尝试了不同的方法，但是没有用！我想与Laravel建立套接字关系，但是它向我发送了这些错误，甚至不允许我运行套接字。我该如何解决？

只需在webpack.mix.js中添加此行

        target: "node",
    externals: {
        express: 'express',

    },

关键依赖项：依赖项的请求是socket.io和express
