node.js - 运行 MERN 测试时出现问题

Question

我正在考虑将 MERN 框架用于一个新项目，但到目前为止，我所看到的并没有让我感到鼓舞。我已按照通过 mern-cli 设置项目的说明进行操作，该项目确实已创建并正确运行，但当我执行时...

npm 运行测试


我明白了...

还有其他人遇到过这种情况吗？我真的很想使用这个框架，但没有功能性的 TDD 是一个阻碍。

使用 Node v6+ 运行 MERN 2.0(当前最新版本)的测试用例失败。以下是我为使测试在 OS X 上运行而所做的工作:

$ brew remove node
$ brew install nvm
$ nvm install 5
$ nvm alias default 5
$ npm install -g mern-cli
$ mern init your_new_app
$ cd your_new_app
$ npm install
$ npm run test
