javascript-GatsbyJS和Superagent：WebpackError：require不是函数

我正在尝试使用gatsbyjs将我的react应用程序构建到静态html页面中.我刚刚尝试了“ gatsby build”,它经历了所有的事情,直到它想要创建静态页面,然后我得到：

error Building static HTML for pages failed

See our docs page on debugging HTML builds for help


  1 | if (global.GENTLY) require = GENTLY.hijack(require);   2 |
> 3 | var crypto = require('crypto');
    | ^   4 | var fs = require('fs');   5 | var util = require('util'),   6 |     path = require('path'),


  WebpackError: require is not a function

  - contact.js:3 Object.<anonymous>
    src/pages/contact.js:3:1

  - sync-requires.js:8 Object.exports.__esModule
    .cache/sync-requires.js:8:53

我正在使用npm 5.5.1.

编辑：

因此,我只是在contact.js文件中注释掉了超级代理,然后构建顺利进行.但是,我不明白为什么这会引起任何问题：

contact.js：

import request from 'superagent'

export default class Contact extends React.Component {

  constructor(props) {
    super(props);
    this.state = { showThankYou: false};

    this.handleSubmit = this.handleSubmit.bind(this);
  }

handleSubmit(e) {
    e.preventDefault();

    request.post('http://www.mywebsite.com/email.php') 
    .send(new FormData(document.getElementById('myForm')))
    .end(function(err, res){
      if (err || !res.ok) {
        console.log('Oh no! error' + err);
      } else {
        console.log('yay got it');
      }
    });

    document.getElementById("myForm").reset();
    this.setState({showThankYou: true});
  }


render() {  
    return (
    <div className="row">

        <div className="form_wrapper">
          <div>
            <form id="myForm" onSubmit={this.handleSubmit}> 

              <label htmlFor="fname">First Name</label>
              <input type="text" id="fname" name="fname" />

              <label htmlFor="lname">Last Name</label>
              <input type="text" id="lname" name="lname" />

              <label htmlFor="email">E-mail Address</label>
              <input type="text" id="email" name="email" />

              <label htmlFor="message">Message</label>
              <textarea id="message" name="message" style={{height: "100px"}}></textarea>

              <input type="submit" value="Submit" />

            </form>
          </div>
        </div>    
    </div>);
}
}

解决方法:

我遇到了同样的错误(本例中是Auth0).我能够通过修改webpack配置来解决它.

盖茨比v1

在gatsby-node.js中添加：

exports.modifyWebpackConfig = ({ config, stage }) => {
  config.plugin("webpack-define", webpack.DefinePlugin, [{ "global.GENTLY": false }])

  return config;
};

盖茨比v2

在gatsby-node.js中添加：

exports.onCreateWebpackConfig = ({ stage, actions, plugins }) => {
  actions.setWebpackConfig({
    plugins: [
      plugins.define({
        'global.GENTLY': false
      })
    ]
  })
}

我最终遇到了其他问题,因为auth0-lock不支持服务器端渲染,但这解决了要求不是函数错误.
