找不到模块：错误：无法解析'crypto'

当我运行ng serve时，我得到以下错误列表。

我的包JSON如下：

{   "name": "ProName",   "version": "0.0.0",   "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",

    "tslib": "^1.9.0",
    "typescript": "^2.9.2",
    "zone.js": "~0.8.26"   } }

我得到的错误：

最近我试图在我正在试验的一个小项目中使用另一个库（tiff.js）时遇到了类似的问题。

我解决这个问题的方法是在devDependencies部分之后添加以下内容到我的package.json文件中。

"devDependencies": {
    ...
},
"browser": {
    "crypto": false
}

尝试在应用程序中使用库时，这似乎没有任何不利影响。
