This won't retain empty words. If you have to do this you can do

irb(main):005:0> "fdsdsf, dsfdsfsd fdsfdsfd dfsfds".gsub(/\s*[\s,]\s*/, ',')
=> "fdsdsf,dsfdsfsd,fdsfdsfd,dfsfds"
irb(main):006:0> "fdsdsf, dsfdsfsd fdsfdsfd dfsfds".gsub(/\s*[\s,]\s*/, ', ')
=> "fdsdsf, dsfdsfsd, fdsfdsfd, dfsfds"

Here's another one

irb(main):008:0> "fdsdsf, dsfdsfsd fdsfdsfd dfsfds".gsub(/\W+/, ',')
=> "fdsdsf,dsfdsfsd,fdsfdsfd,dfsfds"
irb(main):009:0> "fdsdsf, dsfdsfsd fdsfdsfd dfsfds".gsub(/\W+/, ', ')
=> "fdsdsf, dsfdsfsd, fdsfdsfd, dfsfds"

Cheers
