我想安装modernizr：
bower install modernizr
并且一切似乎都没问题，但是当我在bower_components / modernizr里面检查时，我看不到任何地方（甚至不是子目录）的modernizr.js或任何具有modernizr.js内容的文件...
如果我安装jQuery
，请注意类似的说明bower install jquery
bower“说”已经安装了jQuery 2.1.1，但我无法在任何地方找到它。 'dist'目录只有jquery.min.map
如果我需要jQuery最新的1.X
bower install jquery#^1
我进入了dist jquery.js等。
为什么我要经历这一切？因为最初我想安装yeoman webapp
yo webapp
继续选择一切（sass，bootstrap和modernizr）。但是当我去运行它时
grunt serve
我明白了：
Running "serve" task
Running "clean:server" (clean) task
>> 0 paths cleaned.
Running "wiredep:app" (wiredep) task
app/index.html modified.

Modernizr没有被注入（当然它不存在!!!）并且jQuery不起作用（index.html中的链接指向什么...... jquery.js不存在，与每个modernizr相同）

当您从bower获得modernizr时，您需要转到下载modernizr的目录并运行npm install。完成后，运行grunt test，grunt将在modernizr文件夹文件夹中创建一个带有modernizr-build.js文件的dist。

我找到了一个解决方案 - 清理缓存：
bower cache clean
并且神奇地一切都好。
