【英文标题】：Ionic: package.json missing start script

【问题描述】：

我的package.json 没有启动脚本，所以 npm start 不起作用。

我的 package.json 看起来像

启动脚本应该包含什么？

【问题讨论】：

请帮我解决这个错误

您确实缺少脚本。事实上，您似乎漏掉了一个完整的问题。我所看到的只是一些乱七八糟的 JSON，它对您的问题一无所知。请准确描述您所坚持的内容、预期行为、表现出的错误行为，以及您为从前者到后者所做的努力。

这里有什么问题

【参考方案1】：

据我发现，Ionic 项目在 package.json 中不使用启动脚本，因此不需要 npm start。

使用ionic start 创建一个新项目并使用ionic serve 在开发过程中运行该项目，如Getting Started Guide 中所述。

还有其他命令可以在需要时构建、部署和打包您的项目，请务必查看 ionic 文档以了解如何以“Ionic 方式”执行这些操作
