Trouble installing cmdstan with cmdstanpy

Modeling

I’m trying to install cmdstan using cmdstanpy.install_cmdstan. I’m getting the following error:

In [1]: import cmdstanpy
cmdstanpy.install_cmdstan()
In [2]: cmdstanpy.install_cmdstan()
INFO:cmdstanpy:CmdStan version: 2.26.1
INFO:cmdstanpy:Install directory: /Users/demetri/.cmdstanpy

INFO:cmdstanpy:ld: warning: directory not found for option '-L/Users/demetri/.cmdstanpy/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb'

INFO:cmdstanpy:make: *** [bin/stansummary] Error 1

Out[2]: False

The error says something about an unsupported file type in the MacOSX10.15 SDK. I’ve removed the CommandLineTools and reinstalled them and still the error persits.

I’m running MacOS 10.15.7 on a 2017 27 inch iMac.

Did you try this solution? (You probably did?)

Yes, tried that solution as well as a re installation of cmdstanpy. Same error persists

Solution was to just create a new conda env. Not ideal, but it worked.
