【问题描述】：

我有这台机器，我安装了 Zsh 和 OhMyZsh，然后我卸载了它们。

现在，当我在 Angular 2 Quick Starter template 上运行“npm start”时，它会返回此错误：

Error occured when executing command: lite-server

从错误堆栈的第二行，我可以看到 Zsh 存在问题，但我不知道如何解决。

谢谢。

【解决方案1】：

我在类似问题上使用了这篇文章的建议：Angular2 QuickStart npm start is not working correctly

它说尝试更改 package.json 中的开头

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

到：

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

看看这是否适合你。

【讨论】：

查看你的依赖是否是最新的。运行“npm outdated”，然后运行“npm update”。抄送：stackoverflow.com/questions/36016905/…
软件包是最新的。我删除了“node_modules”文件夹并运行“npm install”

【解决方案2】：

试试

在您的快速入门目录中打开 2 个 cmd 实例：

窗口 1# npm run build: 观看

那么……

窗口 2# npm 运行服务

它将打开浏览器窗口并运行应用程序
