Gatsby-图像道具类型失败 [英] Gatsby-Image failed prop type

我试着让我的可湿性粉剂帖子的特色图片发布到网站上。我遵循了this教程，现在我可以在网站上看到特色图片，但我也收到了这样的警告：

              width
              height
            }
          }
        }
      }
    }
  }

Gatsby-config.js文件：

module.exports = {
  siteMetadata: {
    title: `Gatsby Default Starter`,
    description: `Kick off your next, great Gatsby project with this default starter. This barebones starter ships with the main Gatsby configuration files you might need.`,

          return entities
        },
      },
    },
    `gatsby-plugin-sitemap`,
  ],
}

我搜索了这类问题，似乎这并不常见。希望在这里有人能帮上忙。 提前感谢！

推荐答案

我从here得到这个问题的答案。我错误地使用了查询。它需要如下所示：

childImageSharp {
    fixed(width: 300, height: 300) {
        ...GatsbyImageSharpFixed
    }
}
