使用gatsby源-文件系统配置构建模式时出错(以下正式教程)

Question

我通过学习https://www.gatsbyjs.org/tutorial/part-five/#source-plugins教程来学习Gatsby，但是在gatsby-config.js中配置gatsby源代码文件系统时被困住了。

我只是使用简单的gatsby配置文件，如tuto中所示：

module.exports = {
  siteMetadata: {
    title: `Pandas Eating Lots`,
  },
  plugins: [
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `src`,
        path: `${__dirname}/src/`,
      },
    },
    `gatsby-plugin-emotion`,
    {
      resolve: `gatsby-plugin-typography`,
      options: {
        pathToConfigModule: `src/utils/typography`,
      },
    },
  ],
}

当我启动dev服务器时，我会得到以下错误：

$ gatsby develop
success open and validate gatsby-configs - 0.036s
success load plugins - 0.199s
success onPreInit - 0.010s
success initialize cache - 0.025s

success onPreBootstrap - 0.013s
success createSchemaCustomization - 0.002s
success source and transform nodes - 0.091s

我正在使用Node版本10.16.3

我试图搜索，但没有找到关于这个特定错误的有用信息。

有人能帮忙吗？非常感谢！

更新gatsby-source-filesystem可能会为您解决这个问题。
