Gatsby development works,Gatsby Build失败:缺少处理文件类型的加载程序

首先,我是新手。我对Jekyll、Lando、Drupal、WordPress、basic Git、HTML5/CSS3并不陌生。我对JS不感兴趣。好吧,那不碍事。

我有一个简单的单页网站(splash page)将演变成一个多页网站。我决定试试盖茨比。这个 gatsby develop 命令运行良好,对于未使用的变量等,我没有es lint错误。这个 gatsby build 命令会产生一个看起来像超级基本的错误。这个网站只有两页404页和一个索引。如果删除404页,索引页上也会出现同样的错误。盖茨比/Webpack似乎对传递的第一条内容感到窒息:

  You may need an appropriate loader to handle this file type.
  | exports.components = {
  |   "component---src-pages-404-js": function componentSrcPages404Js() {
  >     return import("/Users/jhogue/github/civicpolicy/src/pages/404.js"
  |     /* webpackChunkName: "component---src-pages-404-js" */
  |     );
   @ ./.cache/production-app.js 18:0-45 21:23-36 26:23-36

因为它只是一个启动页,所以没有数据源,没有标记文件,没有要迭代的页面数组。很简单。

我的依赖项列表如下:

"dependencies": {
    "css-mqpacker": "^7.0.0",
    "gatsby": "^2.0.117",
    "gatsby-cli": "^2.4.9",

任何指点都将不胜感激。谢谢。
