Angular 解决 Can't resolve errors (crypto, fs, http, https, net, path, stream, tls, zlib)

原因

浏览器上不支持crypto, fs, http, https, net, path, stream, tls, zlib。

解决方法

在package.json中添加以下内容：

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