graphql-标记/加载程序:模块构建失败，GraphQLError:语法错误

Question

我正面临着奇怪的问题。使用Vue-CLI3 3 npm run serve。

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
      }
    }
  }

在运行npm run serve时，我会得到以下错误：

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

使用：

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

我正在慢慢地假设这可能是我的Babel或Vue配置的一个错误？有人能弄清楚这事吗？

谢谢!

我也面临着同样的问题，似乎有两个装载机造成了坠机。

我安装了graphql-tag和webpack-graphql-loader。

尝试卸载包含阿波罗或graphql的每个包，并再次使用vue cli重新安装。vue add apollo。对我起作用了。
