Gruntjs grunt bower安装什么都不做？

我对格伦特/鲍尔很陌生。我试图做的是在我的应用程序上安装依赖项，并将它们直接注入到我的源代码中

我会这样做：

bower install socket.io-client

其次是

grunt bower-install

由于我希望在我的

index.html

中安装新的依赖项，实际上我的

grunt-service

显示：

>> File "app/index.html" changed.

... Reload app/index.html ...
Completed in 0.000s at Wed Mar 19 2014 15:06:11 GMT+0100 (CET) - Waiting...

然后我检查我的index.html文件，看看没有任何变化。此外，我可以在浏览器控制台上检查

io

是否不可用

我做错了什么？grunt bower的安装不是现成的吗？或者我需要更改它吗？grunt bower install在做什么，从而触发对

grunt serve

输出的更改
