Describe the problem

1. Downloaded jep from source
2. Ran the following command to install jep:

   ARCHFLAGS="-arch x86_64" python3 setup.py build install

3. run the following to test the install:

   ./build/scripts-3.8/jep 

   And I get the following error:

   java -classpath /Library/Python/3.8/site-packages/jep/jep-3.9.1.jar -Djava.library.path=/Library/Python/3.8/site-packages/jep jep.Run /Library/Python/3.8/site-packages/jep/console.py

Search for existing solutions As far as I can tell the install went well. Everything is looking good to me as shown here:

Environment (please complete the following information):

Any help would be greatly appreciated :)

It looks like it found the jep library but not Python's library. Can you please open up the jep script in a text editor and see what PYTHONHOME is set to and if that is correct or not. Also the install is supposed to put the jep script in a bin directory alongside Python's executables, you might try running the installed one instead of the one in the build directory. Last but not least, you could try setting the DYLD_LIBRARY_PATH environment variable to include the directory where the python library is located.

Found where jep is installed, it was under /usr/local/bin/jep and this one runs properly. Next step will be to try and invoke some python code from java. Thanks a lot for unblocking me @ndjensen
