Question

我考虑将MERN框架用于一个新项目，到目前为止，我并没有因为我所看到的而受到鼓舞。我已经按照mern-cli设置项目的说明进行了操作，项目确实已经创建并且运行正常但是当我执行时...

npm run test

我明白了......

有没有人碰到这个？我真的想要使用这个框架，但没有功能性TDD是一个显示阻止。

Answer 1

为节点v6 +运行MERN 2.0（当前是最新版本）的测试用例失败。以下是我在OS X上进行测试所做的工作：

$ 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

Answer 2

在其他帖子/网站上找到：更新package.js中的test脚本，并将--harmony-proxies更改为--harmony。（参考n-makarov在2月12日发表评论：https://github.com/coryhouse/react-slingshot/issues/366）
