I installled chemmineR and ChemmineOB on my mac osx (10.13.x) like this:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install("ChemmineR", version = "3.8")

Then after installing chemmineR, I installed openbabel from there: http://sourceforge.net/projects/openbabel/files/openbabel/2.3.1/OpenBabel-2.3.1.mac.zip/download

and after this I installed ChemmineOB, this way:

BiocManager::install("ChemmineOB", version = "3.8")

After this on R command line:

library("ChemmineR")
library("ChemmineOB")

Error: package or namespace load failed for ‘ChemmineOB’:
 .onLoad failed in loadNamespace() for 'ChemmineOB', details:

First, can you check to see if the file /Library/Frameworks/R.framework/Versions/3.5/Resources/library/ChemmineOB/libs/ChemmineOB.so exists or not?

Also, can you show me the output of ".libPaths()"?

Thanks. Kevin

Yes it exists, and the output of .libPaths is /Library/Frameworks/R.framework/Versions/3.5/Resources/library

Did the location of the installed libopenbabel.so get added to the LDLIBRARYPATH? Maybe something like

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

Upon closer inspection of the error message, I see that it is actually failing to load /usr/local/opt/open-babel/lib/libopenbabel.5.dylib, not the ChemmineOB.so as it first seemed to me. First, confirm that file does exist. I'm not really a mac developer, but this stack overflow page seems to have some helpful suggestions:

https://stackoverflow.com/questions/17703510/dyld-library-not-loaded-reason-image-not-found

One suggestions is to set the environment variable DYLD_LIBRARY_PATH the location of the dylib file, so that would be "/usr/local/opt/open-babel/lib/" in this case.

Also, setting the LD_LIBRARY_PATH to this same directory would be worth trying also.
