我正在将角度应用程序从5迁移到6.运行

ng update @ angular / cliand ng update @ angular / core

但是现在如果我运行构建,我会收到此错误

package.json在devDependencies中包含“typescript”：“> = 2.7.0< 2.8.0” 清理npm缓存并重新安装所有软件包,但它没有帮助. 有同样问题的人吗？

干净地重新安装打字稿

- npm uninstall -g typescript
- npm uninstall typescript
- npm install -g typescript
- npm install typescript@2.7.2
