从Angular2升级到Angular4后,我在CLI中收到这些错误。尽管我的应用程序在升级后仍然可以运行,但是我只是想知道如何或是否可以解决这些错误。有任何想法吗?
升级前的Package.json:

最佳答案
您升级了@angular库,但没有升级必需的依赖项。我建议您使用npm-check-updates。这是升级package.json中所有依赖项的最简单方法。尝试这个:
步骤1. 要安装npm-check-updates,请执行以下操作:
npm i -g npm-check-updates
步骤2. 升级所有依赖项:
npm-check-updates -u
@EDIT:或最新版本的npm-check-updates:
ncu -a
步骤3. 要安装升级依赖项,请执行以下操作:
npm install
