问题
I've been switching to the 1.13.2 version of ember on a git branch, and now I want to come back to 1.11.1 when going back to an other branch.
I've been running npm install and bower install without failure.
But when I run ember server I run into the following error :
Missing bower packages:
Package: ember
* Specified: 1.11.1
* Installed: 1.13.2
Run `bower install` to install missing dependencies.
Running bower install again does not solve the problem, neither does bower cache clean.
回答1:
Do
$ rm -rf bower_components
$ bower cache clean
$ bower install
