angular - 升级到 angular9 问题：找不到节点的导出名称

Question

升级到 Angular 9 并尝试运行我的项目后，我收到了这个错误：

Compiling @angular/common/http : module as esm5
Compiling angular-font-awesome : module as esm5
Compiling angular-font-awesome : module as esm5
Error: Error on worker #5: Error: Failed to find exported name of node (CommonModule = (function () {
    function CommonModule() {
    }
    return CommonModule;
}())) in 'C:/Users/.../node_modules/angular-font-awesome/dist/angular-font-awesome.es5.js'.

这是运行 ng version 的结果：

Angular CLI: 9.1.0
Node: 10.15.0
OS: win32 x64

Angular: 9.1.0
... animations, cli, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic

webpack                           4.42.0

PS：我运行“ng update”并得到“我们分析了您的 package.json，一切似乎都井井有条。'

删除后问题解决

1. 我的 package.json 中的 angular-font-awesome
2. 来自 app.module.ts 的 AngularFontAwesomeModule

并运行 npm install
