angular版本问题&compiler_cli_1.readConfiguration is not a function

问题一、angular版本问题

cielo@cielo-ThinkPad-E550:~/cprogrames/test-bna/angular-test$ ng serve
The serve command requires to be run in an Angular project, but a project definition could not be found.

用npm start也是同样的问题。

cielo@cielo-ThinkPad-E550:~/cprogrames/test-bna/angular-test$ npm start

> angular-test@0.0.1 start /home/cielo/cprogrames/test-bna/angular-test
> ng serve --proxy-config proxy.conf.js --host 0.0.0.0

该问题解决方案：

ng update @angular/cli --migrate-only --from=1.7.3

其实我也在starkoverflow看到了。

我的版本明明是7.3.8，但是–from=【】这块写7.3.8没有用。
不过运行了之后好了似乎。报了新的错误

问题二

红一片，我的心情不知道该如何描述。

cielo@cielo-ThinkPad-E550:~/cprogrames/test-bna/angular-test$ npm start

> angular-test@0.0.1 start /home/cielo/cprogrames/test-bna/angular-test
> ng serve --proxy-config proxy.conf.js --host 0.0.0.0

解决方法：
据说仍然还是版本更新不彻底。只好强制一点了。

ng update @angular/compiler-cli --force

ok了，我这样算是完整地跑了一个网页的例子了。

想哭。
