[julia-users] counts([1,2,2,3]) works on MAC but not on WIN64?

[gdeloscampos]

Hello, I wrote some JULIA script and test it for long time on a MAC, when I 
tried to run the same code on a Windows machine I got an error with the 
counts() function.

To narrow this to its essence

   counts([1,2,2,2,3,3])

returns the expected outcome in MAC

julia> counts([1,2,2,2,3,3])
3-element Array{Int64,1}:
 1
 3
 2

And when I run the same command in a Windows machine I get

ERROR: no method counts(Array{Int64,1},)

Am I missing something?

Thanks
