我已经卸载了@angular/cli 并清除了缓存，再次安装但面临同样的问题.
I have uninstall @angular/cli and cleared the cached, again installed but facing same issue.
请提出建议.
推荐答案
这可能是由于不同版本的 angular-cli.检查 angular-cli 的版本，你应该没有版本 6，而是使用 1.7.原因在 angular 6 中，配置在 angular.json 文件中.在 1.7 版中，配置位于 angular-cli.json
This could be due to different versions of angular-cli. Check the version of angular-cli, you should not have version 6, but use 1.7. Cause in angular 6 the configuration is in angular.json file. In version 1.7 the configuration is in angular-cli.json
