我正在尝试将我现有的ReactJS应用程序与WordPress后端迁移到GatsbyJS。我是GatsbyJS的新手，并按照他们的页面上的说明在Windows 10机器上安装。安装运行得很好，我可以开始我的迁移过程，但过了一段时间，我只得到了以下错误时，试图加载页面：

TypeError: Cannot read property 'component---src-pages-index-jsx' of undefined

我试着删除我自定义的组件，直到我得到了正常的启动样本。但它仍然不起作用。所以我继续，甚至创建了一个新的项目来测试gatsby-cli是否仍然有效。但卸载和重新安装软件包仍然没有解决我的问题。任何帮助或提示将不胜感激。
