Question

我跑步时

ng serve --watch

我收到这些构建错误：

所有错误都与无法找到node.js核心模块定义有关，这似乎很奇怪，特别是考虑到我安装了节点类型：

有人知道会发生什么吗？

ng --version的意思是：

看起来像是因为我安装了Facebook软件包“ fb”，其中使用了一些核心的node.js模块。我想在浏览器中使用该程序包，不确定是否会运行，但是要忽略浏览器版本中的那些模块，可以将其放在package.json中：

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

是的，行不通的，显然需要安装与NPM上名为“ fb”的JS sdk不同的JS sdk，目前正试图找出安装方法：

ng serve找不到node.js核心模块
