我正在尝试使用 graphql 后端（elixir/phoenix）设置 React/Apollo 前端。我做了npm install apollo-boost react-apollo graphql --save然后尝试import ApolloClient from "apollo-boost";在我的index.js中但我得到了

Uncaught Error: Cannot find module 'graphql' from 'apollo-link-state/lib/bundle.umd.js'
    at require (app.js:61)
    at expanded (app.js:34)

在我的浏览器控制台中。我找不到任何相关问题。你能指出哪里出了问题吗？这是我的package.json。

我通过从ghci检查它来声明类型声明但是加载模块会给出错误:

     Couldn't match expected type ‘a’ with actual type ‘Double’
     ‘a’ is a rigid type variable bound by

     In the expression: ((phi ^ n) - (minusphi ^ n)) / sqrt 5
