我想对我的软件进行一些测试，所以我按照互联网上的一些教程并找出软件包 实用流星：摩卡.但是在安装软件包并打开本地(不编写任何测试(之后。我收到错误大喊大叫：

我正在使用流星 1.6.1.1
我会把这个作为一个答案，因为它可能仍然与新用户达到相同点有关。
practialmeteor:mocha是一个推荐的软件包，但不再与 Meteor 兼容>=1.6.1，并且不再维护它的可能性非常高(正如您在他们的开放 gh 问题上看到的那样(。
替代套餐包括
-
cultofcoders:mocha -
meteortesting:mocha
我也遇到过这样的事情，所以我真的花了一些时间才弄清楚。
根据带有Angular教程的Meteor Todo应用程序，建议使用practicalmeteor:mocha包。有趣的是，meteortesting:mocha用于典型的脚手架项目。
"scripts": {
"start": "meteor run",
"test": "meteor test --once --driver-package meteortesting:mocha",
"test-app": "TEST_WATCH=1 meteor test --full-app --driver-package meteortesting:mocha",
"visualize": "meteor --production --extra-packages bundle-visualizer"
},
但是，仅使用从practicalmeteor:mocha分叉的cultofcoders：mocha才起作用。
meteor remove practicalmeteor:mocha
meteor add cultofcoders:mocha
meteor test --driver-package cultofcoders:mocha
享受编码！
