AngularUniversal prerendering error: UnhandledPromiseRejectionWarning: Error: No NgModule metadata found for 'class{}'
AngularUniversal prerendering error: UnhandledPromiseRejectionWarning: Error: No NgModule metadata found for 'class{}'
目标
问题看起来很啰嗦 - 事实并非如此！
我正在使用 Angular Universal 来实现 SSR，紧随其后 tutorial。安装了Universal/express-engine，在dist/projectname/server文件夹中生成了main.js，我在项目根目录下创建了一个prerender.js文件夹。
问题
当我尝试 npm run prerender 时，它开始进行预渲染，直到最终遇到以下错误：

期望的结果
预渲染我们主要 HTML 路线的 HTML，并将其输出到文本文件。
我试过的
This: 删除 main.ts 中 bootstrap 的链式 .catch(err...) 函数 - 同样的错误
This：删除节点模块，package.json，运行 npm install，ng build，ng serve - 同样的错误，还有 package.json 没有像建议的答案那样重新生成，我想我已经破坏了我的应用程序
This：更新 AngularCLI 和 Webpack - 同样的错误

David 发现 Ivy 有错误。然后我在 tsconfig.json > compilerOptions > enableIvy 中启用了常春藤，它抛出了一堆错误 re fontawesome:
Warning: Invalid constructor parameter decorator in C:/Users/odubh/Documents/Personal_Web_Projects/Hibernio.com/Hibernio0.3/hibernio/node_modules/angular-font-awesome/dist/angular-font-awesome.js:
function () { return [
{ type: LocationStrategy, },
]; }
我以前在实现 fontawesome 时不得不禁用 Ivy，因为它们似乎一起导致错误，而 Whosebug 的解决方案似乎是禁用 Ivy。现在我需要 Ivy 来实现 Universal，但我不知道该怎么做才能让这两个包一起工作——最好启用 Ivy，因为这似乎是推荐的。
感谢 David 发现 Ivy 问题。
您需要启用 Ivy 才能解决第一个问题 (No NgModule found ...)。
对于第二个（Invalid constructor parameter decorator），原因可能是您正在使用 angular-font-awesome，它不再维护并且不适用于 Ivy
因此请卸载该软件包 (npm uninstall angular-font-awesome -S) 并仅保留 fortawesome 个软件包：
"@fortawesome/angular-fontawesome": "^0.6.1",
"@fortawesome/fontawesome-free": "^5.13.1",
"@fortawesome/fontawesome-svg-core": "^1.2.29",
"@fortawesome/free-brands-svg-icons": "^5.13.1",
"@fortawesome/free-regular-svg-icons": "^5.13.0",
"@fortawesome/free-solid-svg-icons": "^5.13.1",
注意：正如我在评论中所说，我认为您不需要创建 prerender.ts 文件。您可以只添加路由以渲染到 angular.json 和 运行 ng run prerender
目标
问题看起来很啰嗦 - 事实并非如此！
我正在使用 Angular Universal 来实现 SSR，紧随其后 tutorial。安装了Universal/express-engine，在dist/projectname/server文件夹中生成了main.js，我在项目根目录下创建了一个prerender.js文件夹。
问题
当我尝试 npm run prerender 时，它开始进行预渲染，直到最终遇到以下错误：

期望的结果
预渲染我们主要 HTML 路线的 HTML，并将其输出到文本文件。
我试过的
This: 删除 main.ts 中 bootstrap 的链式 .catch(err...) 函数 - 同样的错误
This：删除节点模块，package.json，运行 npm install，ng build，ng serve - 同样的错误，还有 package.json 没有像建议的答案那样重新生成，我想我已经破坏了我的应用程序
This：更新 AngularCLI 和 Webpack - 同样的错误

David 发现 Ivy 有错误。然后我在 tsconfig.json > compilerOptions > enableIvy 中启用了常春藤，它抛出了一堆错误 re fontawesome:
Warning: Invalid constructor parameter decorator in C:/Users/odubh/Documents/Personal_Web_Projects/Hibernio.com/Hibernio0.3/hibernio/node_modules/angular-font-awesome/dist/angular-font-awesome.js:
function () { return [
{ type: LocationStrategy, },
]; }
我以前在实现 fontawesome 时不得不禁用 Ivy，因为它们似乎一起导致错误，而 Whosebug 的解决方案似乎是禁用 Ivy。现在我需要 Ivy 来实现 Universal，但我不知道该怎么做才能让这两个包一起工作——最好启用 Ivy，因为这似乎是推荐的。
感谢 David 发现 Ivy 问题。
您需要启用 Ivy 才能解决第一个问题 (No NgModule found ...)。
对于第二个（Invalid constructor parameter decorator），原因可能是您正在使用 angular-font-awesome，它不再维护并且不适用于 Ivy
因此请卸载该软件包 (npm uninstall angular-font-awesome -S) 并仅保留 fortawesome 个软件包：
"@fortawesome/angular-fontawesome": "^0.6.1",
"@fortawesome/fontawesome-free": "^5.13.1",
"@fortawesome/fontawesome-svg-core": "^1.2.29",
"@fortawesome/free-brands-svg-icons": "^5.13.1",
"@fortawesome/free-regular-svg-icons": "^5.13.0",
"@fortawesome/free-solid-svg-icons": "^5.13.1",
注意：正如我在评论中所说，我认为您不需要创建 prerender.ts 文件。您可以只添加路由以渲染到 angular.json 和 运行 ng run prerender
