离子构建的问题

Question

我正在学习ionic，在写命令的时候遇到以下问题

ionic build

我要生成文件夹www

https://github.com/jquishpe/imagenionic/blob/master/error1.png

C:\Personal\ionic\platzi-music>ionic build
> ng.cmd run app:build
Generating ES5 bundles for differential loading...
An unhandled exception occurred: Call retries were exceeded
See "C:\Users\HITSS\AppData\Local\Temp\ng-sOfQFc\angular-errors.log" for further details.
[ERROR] An error occurred while running subprocess ng.

        ng.cmd run app:build exited with exit code 127.

        Re-running this command with the --verbose flag may provide more information.

ionic build --verbose

文件内容 C:\Users\HITSS\AppData\Local\Temp\ng-sOfQFc\angular-errors.log
