因为最开始安装的时候，nodejs的目录是指向到C盘User目录下面的。所有的-g安装的包，也就全部都在那个目录下面了。
但通常情况下，新建项目都会随意放在其他盘里，于是基于这些包的安装，必须先引导到你的项目的目录下面去执行安装命令（npm install）。
在安装完karma的时候(命令：npm install karma)，一直提示：no provider for framework:jasmine... 错误。后台经人指点，
进行了karma的初始化（命令：karma init，然后一直回车）。

"**/*.swp". 24 Enter empty string to move to the next question. 25 > 26 27 Do you want Karma to watch all the files and run the tests on change ? 28 Press tab to list possible options. 29 > yes 30 31 Config file generated at "D:\workspace\javascript\karma\karma.conf.js".
最后再安装jasmin（命令：npm install karma-jasmine）。
最最后，配置测试文件的路径，输入：karma start，就OK了！
