Question

我从盖茨比开始。尝试使用gatsby-source-pg插件。但是面临多个graphql版本的问题。我在github上问这个插件的作者这个问题，他在回答我的问题上非常有帮助。

但是也许我在这里缺少什么。

我们非常感谢您的帮助。

Answer 1

啊..找出正确的版本是很棘手的..

我用gatsby new <project_name>创建了一个新项目，并做了npm install。已安装npm install --save gatsby-source-pg

的插件

此后，我在graphql中搜索了名为node_modules的文件夹，然后准备了以下解决方案列表-

  "resolutions":{
    "eslint-plugin-graphql/graphql": "14.1.1",
    "express-graphql/graphql": "14.1.1",
    "graphql-tools/graphql": "14.1.1",
    "apollo-link/graphql": "14.1.1",
    "apollo-utilities/graphql": "14.1.1",
    "gatsby-source-graphql/graphql": "14.1.1",
    "gatsby-source-pg/graphql": "14.1.1",
    "@types/graphql": "14.1.1"
  }

但是后来以某种方式，当我做yarn install时，@types说它不喜欢14.1.1并提供了多种版本。我从显示的列表14.0.7中选择了最新的一个，然后继续安装。仍然会生成如下警告-

yarn install
yarn install v1.12.3
info No lockfile found.

[4/4] Building fresh packages...
success Saved lockfile.

但是现在，我可以使用GraphiQL游乐场来执行我的graphql查询，也可以在项目中执行。

更新：

您可以将分辨率降至最低，而只需说：

"resolutions:" {
     "graphql": "14.x"
}

特别感谢Postgraphile的@benji

Answer 2

运行npm list graphql

然后，检查找到的graphql的最高版本。

然后，将其添加到您的package.json：

  "resolutions":{
    "graphql": "<highest found version>"
  }

然后，删除您的package-lock.json和node_modules文件夹。运行npm install

带有graphql多个版本的gatsby-纱线分辨率
