Thanks, Nathan. I will try this way of building yt with rockstar and if stuck somewhere let you now. Thanks and regards -Prateek On Sun, Oct 15, 2017 at 11:50 PM, Nathan Goldbaum <nathan12343@gmail.com> wrote:

The install script tries to build rockstar using conda-build. This is failing somehow. Fortunately it isn't strictly necessary to use the install script to do this.

Instead, you might try following the instructuctions to build yt with rockstar support here:

One could also try modifying the install script to not use conda-build for rockstar, as I doubt it's actually necessary.

Please provide me some solution so that I can successfully enable ROCKSTAR.

Thanks
