　　报错缘由：多是因为angular/cli版本与项目不匹配致使java

解决办法：node

　　升级angular/clinpm

1.全局卸载angular/clijson

npm uninstall -g @angular/cli

2.清理lua

npm cache verify

3.全局安装angular/clispa

npm install -g @angular/cli@latest

4.在项目路径下卸载angluar/cliblog

npm uninstall --save-dev @angular/cli

5.在项目路径下安装：ip

npm install --save-dev @angular/cli@1.7.4

6.项目路径下npm install或者yarn installget

7.在npm安装后修复问题：

npm audit fix

8.解决与“angular.json”相关的问题：

ng update @angular/cli --migrate-only --from=1.4.9
