SPAWN env | grep -i ferretTo check (2), go to your anaconda directory. (I don't know where yours is, but mine is under /usr/local/ .) Then, do this$ find . -iname '*pyferret*'I find the library, which is /usr/local/miniconda3/envs/FERRET/lib/python3.6/site-packages/pyferret/libpyferret.cpython-36m-darwin.so .Cheers,Ryo
