cmdstanR install trouble

I have a lot of time issues installing CmdStanR on my system.

The issue is with my system causing warnings during unpacking with tar. These warnings are turned into errors by default resulting in installation failure. I have to set the variable


in order to avoid that. Maybe we include this note somewhere? It’s probably not only me running into this.


You are using a mac right? We test with Windows and Linux and havent seen those yet.

Is this due to the warnings on building cmdstan?

I am on Mac and get this all the time.

There is probably some mis-configuration with the local stuff. This causes tar to emit a stupid warning which makes the install fall over.

Ah, makes sense and since its installed via Github its an error. Will add to the getting started text for anyone experiencing issues.
