I’ve just started using optparse. I’m hitting this needless argument  
error when one of my commandline args excepts strings… I’ve looked  
around on google seeing that this was a bug that was fixed at some  
point. How can I get around it?

thanks…

it means that you defined are argument like this

‘–foo’

but are giving it like this on command line

a.rb --foo=value

if you want an option to take values use

‘–foo=value’  
‘–foo=this\_can\_be\_anyword’
