所以我升级到角度4+只是为了让我可以利用通用包进行服务器端渲染以实现搜索引擎优化目的.我在现有的angular 2+项目中实现了这一点,将其升级为angular 4+并从https://github.com/evertonrobertoauler/cli-universal-demo/commit/a2610286bd3db5d4f4cce4318d7c220c11963eb6完成了所有必要的配置.

我使用ng-bootstrap https://ng-bootstrap.github.io/#/home(v1.0.0- alpha.22)只有一个区别.但是当我使用npm run start-u-dev运行节点服务器时,我在ng-bootstrap中的import关键字出现了这个错误.
