ng serve 在 BoUoW 上使用 Angular CLI 创建的 Angular 2 上失败

Question

我在海拔模式下运行 BoUoW 并安装了 @angular/cli 并使用新命令创建了一个示例项目。

当我尝试通过 npm start 运行应用程序时，它通过说明错误 ng serve failed 而失败，并将其归咎于 npm 和节点版本问题或应用程序本身。 npm 和 node 版本是最新的。

任何 angular 2 专家建议还是我使用了错误的样板应用程序？

编辑：

1. @angular/cli: 1.0.0-beta.32.3
2. 节点：6.9.5
3. npm: 3.10.10

编辑 3：重现步骤

注意我在 14393.693 / 14.04.5 LTS 上使用 BoUoW

sudo n v7.5.0
npm install -g @angular/cli
ng new my-project
cd my-project
npm start

Answer 1

你有旧版本的 node 和 npm。当前版本是：

节点 - v7.5.0
南 - 4.1.2

请升级并重试。
顺便说一句，使用 Angular CLI，你可以直接 ng 服务。无需使用
npm start。
