我正在考虑将MERN框架用于新项目，到目前为止，我所看到的并没有受到鼓舞。我遵循了通过mern-cli设置项目的说明，并且确实创建了该项目并且该项目可以正确运行，但是当我执行时...npm run test
我知道了

还有其他人遇到吗？我真的很想使用这个框架，但是没有功能性的TDD是一个阻碍。
最佳答案
对于节点v6 +，运行MERN 2.0（当前最新版本）的测试用例失败。为了使测试在OS X上正常运行，我做了以下操作：
$ 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
关于node.js - 运行MERN测试时出现问题，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/40581912/
