Question

我用版本2.1.2（我按照教程）学习Angular2，但是当我做NPM启动时出现问题问题出在以下版本：2.1.2 - 2.3.0 - 2.4.0。（版本：4可以正常工作）

主要错误是：错误！代码ELIFECYCLE

有什么想法吗？谢谢

Answer 1

有两种可能的方式：

1）通过执行命令单独运行lite服务器：

npm run lite

2）在脚本中修改start命令：

将现有的开头替换为以下内容：

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "

ELIFECYCLE Node.js出错，这有多正确？
