vue.js - graphql-标签/加载器 : Module build failed with GraphQLError: Syntax Error

Question

我面临的奇怪问题。使用 Vue-CLI3 npm runserve。

具有以下配置:

// vue.config.js
module.exports = {
  chainWebpack: config => {
    // GraphQL Loader
    config.module
      .rule('graphql')
      .test(/\.graphql$/)
      .use('graphql-tag/loader')
      .loader('graphql-tag/loader')
      .end();
  }
};

和一个 .graphql 文件:

mutation AddOfficeMutation(
    $name: String
    $location: String
  ) {
    createOffice(
      input: {office: { name: $name, location: $location }}
    ) {
      office {
        id
        name
        location
      }
    }
  }

运行npm runserve时，出现以下错误:

ERROR  Failed to compile with 1 errors                                                                                                                                                           1:11:08 PM

 error  in ./src/graphql/AddOfficeMutation.graphql

使用:

• “graphql”:“^14.0.2”
• “graphql-tag”:“^2.10.0”

我慢慢假设这可能是我的 Babel 或 Vue 配置错误？ 任何人都可以阐明这一点吗？

谢谢!

Answer 1

我遇到了同样的问题，似乎有 2 个加载程序导致了崩溃。

我已经安装了 graphql-tag 和 webpack-graphql-loader 。

尝试卸载包含 apollo 或 graphql 的每个软件包，然后再次使用 vue cli 重新安装。 vue 添加 apollo。它对我有用。
