Karma-jasmine 未安装

Question

我是 Unit Testing 的新手，所以我今天才知道 Jasmine 和 Karma。

我安装了 Karma：

npm init
npm install karma --save-dev
npm install -g karma-cli
npm install karma-jasmine --save-dev
npm install karma-chrome-launcher --save-dev
karma init

然而，当我尝试启动 karma start karma.conf.js 时，它抛出了一个错误：

Error: Cannot find module 'jasmine-core'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.require.resolve (module.js:389:19)

我试过全局安装核心：

npm install -g jasmine-core

但这并没有解决问题。

当我尝试安装 npm install karma-jasmine 时，我收到一条错误消息：

 karma-jasmine@0.3.6 requires a peer of jasmine-core@* but none was installed.

Answer 1

https://github.com/karma-runner/karma-jasmine

Note: Since karma-jasmine 0.3.0 the jasmine library is no longer bundled with karma-jasmine and you have to install it on your own. You can simply do it by:

npm install jasmine-core --save-dev

$ npm install jasmine-core --save-dev
$ npm install karma-jasmine --save-dev

Answer 2

问题是 Karma 运行全球通用。

我的解决方案（至少对我来说是最简单和无痛的）是用 npm scripts test 命令包装 karma start 命令，这样任何命令在本地上下文中都是运行 .

在package.json中，在"scripts": {}中添加"test": "karma start"。

"scripts": { "test": "karma start", [...] },
