Npm安装Karma-jasmine不起作用

Question

我只需按照其中的说明进行操作：http://karma-runner.github.io/0.12/intro/installation.html

Karma已正确安装。但是，我不能安装karma-jasmine和karma-chrome-launcher。实际上，我对自述文件有很多警告：

npm WARN package.json abbrev@1.0.4 No README data
npm WARN package.json ansi@0.2.1 No README data
npm WARN package.json archy@0.0.2 No README data
npm WARN package.json asn1@0.1.11 No README data

..。

然后是一些未满足的依赖关系：

*

npm WARN unmet dependency /usr/lib/node_modules/block-stream requires inherits@'~2.0.0' but will load
npm WARN unmet dependency undefined,
npm WARN unmet dependency which is version undefined
npm WARN unmet dependency /usr/lib/node_modules/fstream requires inherits@'~2.0.0' but will load

你知道这是从哪里来的吗？
