【问题描述】：
我有一个正在添加的 Gatsby 安装，但是，在尝试构建一些 graphQL 构建时数据获取时，我遇到了一个导致错误的问题运行 npm start (gatsby develop) 或 gatsby build。
我安装了 gatsby-source-graphql，如下所述： https://www.npmjs.com/package/gatsby-source-graphql
我将它包含在我的 gatsby-config.js 中，如下所示：
module.exports = {
// Optional
siteMetadata: {
title: `Title from siteMetadata`,
},
plugins: [
{
resolve: `gatsby-plugin-manifest`,
options: {
name: "Project Template",
short_name: "PT",
start_url: "/",
background_color: "#6b37bf",
theme_color: "#6b37bf",
// Enables "Add to Homescreen" prompt and disables browser UI (including back button)
// see https://developers.google.com/web/fundamentals/web-app-manifest/#display
display: "standalone",
icon: "src/images/icon.png", // This path is relative to the root of the site.
// An optional attribute which provides support for CORS check.
// If you do not provide a crossOrigin option, it will skip CORS for manifest.
// Any invalid keyword or empty string defaults to `anonymous`
crossOrigin: `use-credentials`,
},
},
{
resolve: `gatsby-source-filesystem`,
options: {
name: `images`,
path: `${__dirname}/src/images`,
},
},
// GraphQL APIs for use during build-time.
// https://www.npmjs.com/package/gatsby-source-graphql
//////////////////////////////////////////////////////
{
resolve: "gatsby-source-graphql",
options: {
// Arbitrary name for the remote schema Query type
typeName: "SpaceX",
// Field under which the remote schema will be accessible. You'll use this in your Gatsby query
fieldName: "spaceX",
// Url to query from
url: "https://api.spacex.land/graphql/",
},
},
// {
// resolve: "gatsby-source-graphql",
// options: {
// // Arbitrary name for the remote schema Query type
// typeName: "SWAPI",
// // Field under which the remote schema will be accessible. You'll use this in your Gatsby query
// fieldName: "swapi",
// // Url to query from
// url: "https://swapi-graphql.netlify.app/.netlify/functions/index",
// },
// },
`gatsby-transformer-sharp`,
`gatsby-plugin-sharp`,
`gatsby-plugin-react-helmet`,
`gatsby-theme-material-ui`,
{
resolve: `gatsby-plugin-nprogress`,
options: {
// Setting a color is optional.
color: `tomato`,
// Disable the loading spinner.
showSpinner: false,
},
},
`gatsby-plugin-transition-link`,
`gatsby-plugin-layout`, // Trial and error showed this needs to be last (But that doesn't mean it will always work in the dev environment, try npm run clean or if that fails - test in build)
],
}
但它会产生这个错误：

我尝试过的：
-
我已经在配置中尝试了两种不同的 gatsby-source-graphql 定义（一次只有一个），但都产生了错误。第二个（上面已注释掉）直接取自The github page example 和Gatsby example。
-
我已尝试更改插件的顺序（我已尝试每个位置）但仍然出现错误。
-
如果我在配置中评论任何和所有 gatsby-source-graphql 部分，它不会产生错误。
-
如果我注释掉所有插件 除了 gatsby-source-graphql 部分之一，我仍然会得到完全相同的错误。
-
我也尝试过删除 node_modules 文件夹，运行 npm run clean，然后再次 npm install，没有任何变化。
-
我也尝试了以下链接中描述的 DanceParty 解决方案，没有任何变化： https://github.com/gatsbyjs/gatsby/issues/8249
-
我尝试运行
npm update和npm install npm@latest -g并没有看到任何变化。
我使用 gatsby info --clipboard 的环境报告是：

有什么想法吗？
【问题讨论】：
-
您在哪里发现可以使用插件的多个实例？ （因为
Duplicate this whole entry to define additional sources.）。重装前有没有运行gatsby clean？ -
我想我只是根据此页面假设它：npmjs.com/package/gatsby-source-graphql，但是，尚未经过测试。我从来没有同时运行过两个 - 一个总是被注释掉。但我都尝试过并收到同样的错误。我已经稍微更新了问题以获取更多环境信息。
-
如果有人偶然发现，只是一个更新：文档的示例暗示，对于多个查询，您在 gatsby-config.js 中定义了插件的多个实例。我现在已经对此进行了测试，并且可以确认它有效。
