Question

我有一个我正在开发的angular 7项目。我使用服务器端渲染来允许facebook搜寻器正常工作。到目前为止，我已经开发了一些组件，还没有遇到任何麻烦。但是现在我遇到了问题，因为我正在使用fullcalendar开发组件...

使用ng s服务应用程序没有任何麻烦。但是，当我尝试使用服务器端呈现npm run build:ssr && npm run serve:ssr构建应用程序时，我现在收到以下错误：npm ERR! code ELIFECYCLE

直到现在我分别创建了npm install和npm audit fix，但这并没有帮助。我想问题出在我的一个 app.module.ts或app.server.module.ts，但我不知道。

以下是错误消息的内容：

C:myApp\dist\server.js:151900

有什么建议可以解决这个问题吗？

问题出在第三方库上。

似乎无法为日历组件导入组件工厂，这使我认为您缺少某些节点依赖项。

验证您已安装@fullcalendar/core @fullcalendar/daygrid软件包。

该库正在使用另一个JavaScript库（“核心”程序包），该库不是为服务器端呈现而设计的。虽然您可以编译该项目。如果“核心”库中的任何内容都无法在NodeJS上运行，那么它很可能无法编译或无法运行。

Answer 2

在server.ts中添加此行

global ['Event'] = null; global ['KeyboardEvent'] = null;
