Gatsby在获取graphql时，在构建过程中出现错误" error : Type with name "File“of exists”

Question

尝试构建一个gatsby网站，但我遇到了一个与graphql模式相关的难以调试的错误(我想)。我得到的错误是：

success open and validate gatsby-configs — 0.004 s
success load plugins — 0.276 s
success onPreInit — 0.004 s
success delete html and css files from previous builds — 0.018 s
success initialize cache — 0.008 s
success copy gatsby files — 0.009 s
success onPreBootstrap — 0.005 s
Starting to fetch data from Prismic
Fetch Prismic data: 919.580ms
success source and transform nodes — 0.975 s
error Type with name "File" does not exists


  Error: Type with name "File" does not exists

我不知道这个类型的File是什么，我在我的文件中找不到这个词的任何匹配项。

有谁知道吗？

Answer 1

在最近更新的gatsby-source-prismic-graphql插件中，所有者推动了对gatsby-image的支持。从那时起，他更新了你应该开始的示例，但是对于现有的项目，你需要添加这三个插件来确保一切都像预期的那样工作：

• gatsby-source-filesystem
• gatsby-transformer-sharp
• gatsby-plugin-sharp

希望能有所帮助。

Answer 2

我也有同样的问题，我添加了gatsby-source-filesystem，这很有帮助。然而，我不清楚为什么棱镜突然开始需要它。早些时候，对于相同的模型，它不是必需的。
