我用angular-cli 6开发了一些角度库。 用量角器运行e2e时出现以下错误：
E/launcher - Error: ReferenceError: window is not defined

Closing report

An unexpected error occurred: undefined
这似乎是由于库sg-ng-core-components中的某些错误导致的，这些组件具有以下依赖性：
"peerDependencies": {
"@angular/common": "^6.0.0-rc.0 || ^6.0.0",
"@angular/core": "^6.0.0-rc.0 || ^6.0.0",
"@angular/platform-browser": "^6.0.0-rc.0 || ^6.0.0",
"@angular/platform-browser-dynamic": "^6.0.0-rc.0 || ^6.0.0",
"@angular/http": "^6.0.0-rc.0 || ^6.0.0",
"@angular/router": "^6.0.0-rc.0 || ^6.0.0",
"ngx-bootstrap": "^3.0.1",
"rxjs": "^6.2.1",
"rxjs-compat": "^6.2.1"
},
在Google上，我找不到解决方案。 有人知道如何解决这个问题吗？
