Answer 1

使用:

ng serve

请参阅angular CLI docs - https://github.com/angular/angular-cli/wiki

Answer 2

升级到角度6后有这个.

似乎CLI命令已更改为:

ng build --configuration <environment-name>

从5迁移到6还创建了一个新的"angular.json"文件,该文件现在包含所有不同的配置及其名称.

Answer 3

查看cli 文档.

我相信你需要在build命令中指定你的项目名称.

ng build [project]

您还可以使用以下命令执行生成构建.

ng build [project] --prod

Answer 4

仔细检查命令行语法。可以显示此错误，ng而不是npm使用package.json快捷方式脚本时显示。

npm run debug   (Good)
ng run debug    (Bad)
