Question

我已经为React Native编写了一些简单的测试并在CircleCI上运行它们，但我收到了以下错误：ReferenceError：Map未定义

我知道Map是一个新的ES6功能，但不确定我为什么会收到此错误。我的测试脚本包含--compilers babel-core/register，但看起来babel正在编译react-native-mock库中的某些代码。

我认为这不是特定于react-native-mock，但我确实注意到库test script需要babel-core/register："test": "mocha --require babel-core/register test/**/*.js",

我也试过了，尽管我在保存的依赖项中使用了babel-core，但我得到了Error: Cannot find module 'js:babel-core/register'。

非常感谢任何建设性的帮助。

对此的解决方案要求我添加circle.yml并指定节点v5.0.0。这使circle.yml能够理解new Map正在做什么。无论出于何种原因，如果没有这项检查，它将无法运作

// circle.yml

machine:
  node:
    version: 5.0.0
