How to get rid of SourceMapConcat build error in emberjs?

I am always getting below error when I try to run ember server --proxy http://localhost:16000/ command. How do I solve this error? I have tried deleting tmp,build,bower_components & node_modules folder and tried with fresh workspace, but still facing the same issue. This is a dev environment, and this is working fine on production, but it is no longer working on my dev system.

Build Error (SourceMapConcat)

ENOENT: no such file or directory, open '/home/rick/Perforce/IIDIQ-UI/tmp/source_map_concat-input_base_path-aeXF7Gds.tmp/bower_components/blockUI/jquery.blockUI.js'
