我有一个 Angularjs 项目，我正在使用 karma 来运行测试。我遇到了一些问题，出现了这个错误:

ReferenceError: Can't find variable: require
at http://localhost:9876/base/src/test/bower_components/angular-animate/index.js?b8fe1c0a06b723a75c7e596fd8a86d91965f681c:1

Reding 到一些论坛，有人告诉我使用 karma browserify，但我现在收到这个错误:

有人知道这是怎么回事吗？这是我的 karma.conf 文件:

最佳答案

我遇到了类似的问题:

Warning: No provider for "framework:mocha"! (Resolving: framework:mocha)

发生这种情况是因为我没有包含该插件。正确配置:

...
singleRun: true,
plugins: ['karma-phantomjs-launcher', 'karma-mocha'], // here
frameworks: ['mocha'],
...

另外值得一提的是，您需要安装插件:

npm install karma-mocha --save-dev

https://www.npmjs.com/package/karma-mocha

经过进一步实验，当您没有包含指定框架的插件时，看起来这是传递的错误消息:

...
plugins: ['karma-phantomjs-launcher', 'karma-mocha', 'karma-chai'],
frameworks: ['mocha', 'chai'],  // Will require the plugins above
...

关于javascript - 错误: No provider for "framework:browserify"!(解决:framework:browserify)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31687669/
