When trying to run hello-world example

import sys
import ghostscriptargs = ["ps2pdf", # actual value doesn't matter"-dNOPAUSE", "-dBATCH", "-dSAFER","-sDEVICE=pdfwrite","-sOutputFile=" + sys.argv[1],"-c", ".setpdfwrite","-f",  sys.argv[2]]ghostscript.Ghostscript(*args)

getting error:

 File "/Users/ddd/sss/ddd/eee.py", line 2, in <module>import ghostscriptFile "build/bdist.macosx-10.6-universal/egg/ghostscript/__init__.py", line 33, in <module>File "build/bdist.macosx-10.6-universal/egg/ghostscript/_gsprint.py", line 290, in <module>
RuntimeError: Can not find Ghostscript library (libgs)

what is this libgs library and how can I get it?

btw I'm on mac

For newer user who are using M1 mac, ghostscript might show a missing libgs file error and the file would be unavailable at usr/local/lib

The issue can be resolved by following these steps, in the same order:

• brew install ghostscript
• conda install ghostscript, which installs the arm_64 based library from conda-forge
• If conda throws a channel error try using conda install -c conda-forge ghostscript
• pip install ghostscript

Note:

1. The libgs.dylib file can be found in the home brew installation of ghostscript
2. Changing the address in _gsprint.py will throw an error as the brew installed version will be arm_64 based and the pip installed version will be OS_X86 based
3. Python doesn't recognise ghostscript module from conda install unless pip install is run, so that is an essential step
