Gatsby - “值”必須至少包含 [icon, icons] 之一

Question

當我在控制台中運行 gatsby develop 時，會出現此錯誤：

 ERROR #11331 PLUGIN Invalid plugin options for "gatsby-plugin-manifest": - "value" must contain at least one of [icon, icons]

我剛剛在此處克隆了一個啟動器 github 分支並安裝了所有節點模塊。 請記住，我是新來的反應/蓋茨比。 我在 web 上搜索了這個錯誤，但沒有找到任何有用的信息。

這是我的 gatsby-config.js：

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.`,
    author: `@gatsbyjs`,
  },
  plugins: [
    `gatsby-plugin-feed`,
    {
      resolve: `gatsby-plugin-manifest`,
      options: {
        name: `Gatsby Starter Blog`,
        short_name: `GatsbyJS`,
        start_url: `/`,
        background_color: `#ffffff`,
        theme_color: `#663399`,
        display: `minimal-ui`,
        icon: `${__dirname}/src/assets`,
      },
    },  
    `gatsby-plugin-react-helmet`,
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `assets`,
        path: `${__dirname}/src/assets`,
      },
    },
    `gatsby-transformer-sharp`,
    `gatsby-plugin-sharp`,
    {
      resolve: `gatsby-plugin-manifest`,
      options: {
        name: `gatsby-starter-default`,
        short_name: `starter`,
        start_url: `/`,
        background_color: `#663399`,
        theme_color: `#663399`,
        display: `minimal-ui`,
      },
    },
    `gatsby-plugin-styled-components`,
    // this (optional) plugin enables Progressive Web App + Offline functionality
    // To learn more, visit: https://gatsby.dev/offline
    // `gatsby-plugin-offline`,
  ],
}

這是我的 package.json：

任何幫助都會得到幫助：:)

Answer 1

您的gatsby-config.js中有兩個gatsby-plufin manifest實例。 刪除其中之一：

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.`,
    author: `@gatsbyjs`,
  },
  plugins: [
    `gatsby-plugin-feed`,  
    `gatsby-plugin-react-helmet`,
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `assets`,
        path: `${__dirname}/src/assets`,
      },
    },
    `gatsby-transformer-sharp`,
    `gatsby-plugin-sharp`,
    {
      resolve: `gatsby-plugin-manifest`,
      options: {
        name: `gatsby-starter-default`,
        short_name: `starter`,
        start_url: `/`,
        background_color: `#663399`,
        theme_color: `#663399`,
        display: `minimal-ui`,
      },
    },
    `gatsby-plugin-styled-components`,
    // this (optional) plugin enables Progressive Web App + Offline functionality
    // To learn more, visit: https://gatsby.dev/offline
    // `gatsby-plugin-offline`,
  ],
}

如果您不想使用圖標，因為它不是強制性屬性，您可以將其刪除。 但是，如果您正在使用它，則必須提供有效的圖標，而不是文件夾：

icon: `${__dirname}/src/assets/iconName.png`,

Answer 2

  icon: `${__dirname}/src/assets`,

上面的行必須指向一個文件，而不是一個文件夾

https://www.gatsbyjs.com/plugins/gatsby-plugin-manifest/#hybrid-mode-configuration

 module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-manifest`,
      options: {
        name: `GatsbyJS`,
        short_name: `GatsbyJS`,
        start_url: `/`,
        background_color: `#f7f0eb`,
        theme_color: `#a2466c`,
        display: `standalone`,
 icon: `src/images/icon.png`, // This path is relative to the root of the site.
      icons: [
        {
          src: `/favicons/android-chrome-192x192.png`,
          sizes: `192x192`,
          type: `image/png`,
        },
        {
          src: `/favicons/android-chrome-512x512.png`,
          sizes: `512x512`,
          type: `image/png`,
        },
      ], // Add or remove icon sizes as desired
      },
    },
  ],
}
