Question

我的代码非常简单：

let casper = require('casper').create({
  pageSettings: {
    loadImages:  false,
    loadPlugins: false,
    userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4'
  }
});

casper.on("page.error", (msg, trace) => {
  this.echo("Page Error: " + msg, "ERROR");
});

casper.on("resource.received", (resource) => {
  console.log('***', resource);
});

casper.start('https://my-app.com/');

casper.then(() => {
  this.test.assertExists('#login-form', 'Form is found');
  this.fill('#login-form', {
    'user-email': 'user@mailcom',
    'pin-number': '1234',
  }, true);
});

casper.run();

当我使用node test.js时，我会收到下一个错误：
