node.js - Angular 6 many Can't resolve errors (crypto, fs, http, https, net, path, stream, tls, zlib)

标签 node.js angular npm webpack angular6

我正在构建一个 Angular 6 应用程序，但每次我想向 localhost 提供服务时，我都会收到以下错误:

这是我的 package.json:

有人知道出了什么问题吗？上面提到的模块都不存在于我的 node_modules 文件中(我可以安装其中的一些，但是现在内置了“crypto”)。我怎样才能得到这些文件夹？它快把我逼疯了。

最佳答案

这是由于导入浏览器中不可用的 Node 模块的依赖项引起的。将给出错误的模块添加到您的 package.json:

"browser": {
    "http": false,
    "https":false,
    "net": false,
    "path": false,
    "stream": false,
    "tls": false
}
