Install Old Version of Julia Using Conda

Hi all,

Because I generally use conda to manage all of my development languages, I also install Julia 1.0 in my Macbook via conda. Now I have been forced to use one package but it is only stable and can pass the installation test in Julia 0.6.

I have searched for some posts but there is no regarding answer about how to install an old version of Julia by conda. Can somebody help me out with this?
