Meteor/React 使用 Enzyme 的 Mocha 测试 - 找不到模块 'has'

Question

如前所述，我是运行一个使用 React 的 Meteor 应用程序，并开始使用 Mocha 编写测试。目前我有一个基本测试，什么都不测试。

client/prospects/ProspectForm.tests.jsx

import React from 'react';
import { shallow } from 'enzyme';

describe('<Foo />', () => {

  it('calls componentDidMount', () => {
  });

});

当我启动测试服务器时出现以下错误

找不到模块 'has'。看起来问题出在 enzyme 上，但是当我创建一个新的 meteor 应用程序并添加 enzyme 和 practicalmeteor:mocha，然后添加相同的测试时它工作正常，所以它一定与我的环境有关应用

这是我的package.json

    {
  "name": "myApp",
  "private": true,
  "scripts": {
    "start": "meteor run"
  },
  "dependencies": {
    "material-ui": "^0.15.0",
    "meteor-node-stubs": "~0.2.0",
    "react": "^15.0.2",
    "react-addons-pure-render-mixin": "^15.0.1",
    "react-datepicker": "^0.27.0",
    "react-dom": "^15.0.2",
    "react-mounter": "^1.2.0",
    "react-s-alert": "^1.1.4",
    "react-tap-event-plugin": "^1.0.0"
  },
  "devDependencies": {
    "enzyme": "^2.3.0"
  }
}

有人知道这里发生了什么吗？

Answer 1

如果您还没有安装 these 2 dependencies，您还需要安装它们：

npm i --save-dev react-addons-test-utils
npm i --save-dev react-dom

看起来你有 react-dom，但你缺少测试工具。

Answer 2

运行 meteor 更新为我解决了这个问题，我也确实必须按照 Davin 所说的去做。
