我正在阅读本教程:https : //www.gatsbyjs.org/blog/2017-07-19-creating-a-blog-with-gatsby/
我已经完成了所有工作,并且遇到了graphQL编译错误:
GraphQL Error There was an error while compiling your site's GraphQL queries.
Invariant Violation: GraphQLParser: Unknown argument `formatString`.
Source: document `BlogPostByPath` file: `GraphQL request`.

这是我的查询:
export const pageQuery = graphql`
query BlogPostByPath($path: String!) {
markdownRemark(frontmatter: { path: { eq: $path } }) {
html
frontmatter {
date(formatString: "MMMM DD, YYYY")
path
title
}
}
}
`
;

编译错误指向日期对象,当我删除它时,日期编译错误就消失了。我的日期对象有什么问题?
