【英文标题】：Gatsby always fetch cached data

【问题描述】：

我使用gatsby-source-git 从 Github repository 中提取文件。它运行良好，但我在 repository 中添加了一些文件，我无法将新文件拉入我的 Gatsby 项目。

如果我在http://localhost:8000/___graphql 中运行此查询：

query MyQuery 
  allMarkdownRemark 
    edges 
      node 
        frontmatter 
          title
        
        fileAbsolutePath
      
    
  

我得到这个结果：

  "data": 
    "allMarkdownRemark": 
      "edges": [
        
          "node": 
            "frontmatter": 
              "title": "Introduction"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/index.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "Conceptual Guide"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/tau-conceptual-guide.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "Tau & Agoras Overview"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/what-is-tauchain-tau.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "FAQs"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/tauchain-agoras-faqs.md"

            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/Tutorials/index.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "Analysis of TauBot.TML"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/Tutorials/analysis-of-taubot-tml.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "TML Bot Tutorial"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/Tutorials/tml-Bot-tutorial.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "Understanding TML"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/Tutorials/understanding-tml-prolog-datalog-tau.md"
          
        ,
        
          "node": 
            "frontmatter": 
              "title": "Quick Start"
            ,
            "fileAbsolutePath": "dev/tau-guide-website/.cache/gatsby-source-git/tau-guide-documents/docs/quick-start.md"
          
        
      ]
    
  

Tutorials 文件夹包含 6 个文件，这些文件不包含在查询结果中。我不知道为什么。

gatsby-config.js

require("dotenv").config(
  path: `.env.$process.env.NODE_ENV`
);

module.exports = 
  siteMetadata: 
    title: "Fan Site"
  ,
  plugins: [
    "gatsby-plugin-react-helmet",
    "svgo",
    "gatsby-plugin-sass",
    "gatsby-plugin-postcss",
    
      resolve: "gatsby-source-filesystem",
      options: 
        name: "data",
        path: `$__dirname/src/data/`
      
    ,
    
      resolve: "gatsby-source-filesystem",
      options: 
        path: `$__dirname/src/pages`,
        name: "pages"
      
    ,
    
      resolve: `gatsby-transformer-remark`,
      options: 
        plugins: [`gatsby-remark-autolink-headers`]
      
    ,
    "gatsby-transformer-json",
    "gatsby-plugin-dark-mode",
    
      resolve: "gatsby-source-prismic-graphql",
      options: 
        repositoryName: "funsite",
        accessToken: `$process.env.API_KEY`
      
    ,
    
      resolve: `gatsby-source-git`,
      options: 
        name: `tau-guide-documents`,
        remote: `https://github.com/TauGuide/tau-guide-documents.git`,
        branch: `master`,
        // Only import the docs folder from a codebase.
        patterns: `docs/**`
      
    
  ]
;

我尝试将local: "/dev/tauguide/tau-guide-documents", 添加为gatsby-source-git 选项，但没有帮助。

我尝试运行gatsby clean，它删除了.cache 文件夹和gatsby develop，但我得到了相同的结果。生成.cache文件夹时，所有文件都在，只有查询结果不包含。

我试图删除该项目并再次从 git 中提取它，但它没有帮助。

【问题讨论】：

看起来Tutorials 中仅缺少 2 个文件：1 和 2。它是否正确？我可以在您发布的查询结果中看到其他人。

@RobinMétral 是的。

【参考方案1】：

Tutorials 文件夹中仅缺少两个文件：step-by-step-guide-how-to-buy-agoras.md 和 step-by-step-guide-how-to-store-agoras.md。

我认为问题在于这些文件中的frontmatter 格式，而不是gatsby-source-git。

如您所见，它们与其他文件的区别在于它们的值中都有冒号：

title: Agoras: How to Store description: Agoras: How to Buy

你需要add quotes around those:

title: "Agoras: How to Store" description: "Agoras: How to Buy"

您的查询可能无法解析这些文件，因此文件没有出现。如果这能解决您的问题，请告诉我！
