I am working on getting the Ganymede kernel installed in my Jupyter environment. Followed the instructions from the docs. Mine is an M1 Macbook pro.

when I execute the following command:

$ java -jar ganymede-2.1.2.20230910.jar -i

I get:

ERROR [    main] Install                                  : Cannot run program "/usr/bin/env bash": error=2, No such file or directory

Any workaround to get this working?

  • /usr/bin/env is the program name; bash is an argument to it, not part of its name. Find whatever is trying to run env bash as a single word and fix that thing. Commented Sep 11, 2023 at 14:50
  • To be very clear, MacOS does ship both /usr/bin/env and bash, so as long as you have a normal PATH, the code works just fine when it's correctly interpreted as two separate arguments; the issue is whatever's misusing ProcessBuilder, treating both words as if they were part of the executable name, whereas only the first one is in fact such a name.

  • Think about filing a bug report at github.com/allen-ball/ganymede -- the author is in a position to fix this; we aren't. (We can help you fix it, if you want to get into ganymede's source code, but if you aren't willing to do that you're interacting as a user rather than as a developer, and Stack Overflow isn't really the right place) Commented Sep 11, 2023 at 14:53
  • ...also, reading the source to github.com/allen-ball/ganymede/blob/…, I see they've got a which function defined. You don't need /usr/bin/env when you have which, as you can just do a PATH lookup directly yourself. Commented Sep 11, 2023 at 14:56
  • (...what's really weird is that from the code on github -- if you're running a binary that genuinely corresponds to the source that's published -- the line in question should be running python3, not running /usr/bin/env bash at all -- but this is something that a debugger is probably the best way to investigate) Commented Sep 11, 2023 at 14:59
