bower-bootstrap-accordion不是

bower-bootstrap-accordion is not registered in the Bower registry and therefore the Bower client cannot find it by name.
You can use the Git repository URL when defining the dependency. This will save the Bower client the need to search for the package URL in the Bower registry.

"dependencies": {
  "bower-bootstrap-accordion" : "git://github.com/ui-bootstrap-bower-test/bower-bootstrap-accordion.git"
}

此外，此软件包还依赖于其他软件包，例如 bower-bootstrap-collapse，bower-bootstrap-transition ，这些软件包也未在Bower注册表中注册.您必须以相同的方式将其包含在依赖项中.
我认为所有这些软件包均来自同一作者- https://github.com/ui-bootstrap -bower-test/

In addition this package has dependencies on additional packages such as bower-bootstrap-collapse, bower-bootstrap-transition which are also not registered in the Bower registry. You will have to include it in the same way in your dependencies.
I think all those packages are from the same author - https://github.com/ui-bootstrap-bower-test/
