This error is produced when trying to use krakatau for bytecode editing with the provided python directory: /usr/bin/python3

The provided directory has no quotes in it and there is a file called python3 in /usr/bin/.

Please try without /usr/bin (only "python3") as the path

@Daswf852 where you ever able to correct this issue? I am experiencing this same issue now and I am not finding much documentation as to fixing it.

@tegid77 I ran into this problem now and found that my specific issue was that I had python 2.7 configured as my Python SDK in my project. It was resolved when I upgraded to python3.8
