I also wrote a bug report (#127553), but I thought of sharing it here too for visibility, in case it saves other macOS users some time.
To reproduce this, get access to a computer with macOS Monterey 12.3+ installed.
Open a terminal with the houdini env set up:
$ open /Applications/Houdini/Houdini19.0.561/Utilities/Houdini\ Terminal\ 19.0.561.app
$ cd /Applications/Houdini/Houdini19.0.561/Frameworks/Houdini.framework/Versions/Current/Resources $ source houdini_setup_bash
Try to run 'houdinifx' from the terminal.
Actual vs expected behavior
Expected behavior:
houdinifxstarts fine from the shell session.Actual behaviour:
$ houdinifx -bash: /Applications/Houdini/Houdini19.0.561/Frameworks/Houdini.framework/Versions/Current/Resources/bin/houdinifx: /usr/bin/python: bad interpreter: No such file or directory
The issue here is that the shebang used is
#!/usr/bin/python:$ cat /Applications/Houdini/Houdini19.0.561/Frameworks/Houdini.framework/Versions/Current/Resources/bin/houdinifx | grep python #!/usr/bin/python
But python2 has been deprecated since Monterey 12.3.
As matter of fact, on a new clean system (without user aliases):
$ which python
$ which python3
/usr/bin/python3.For reference, see:
- https://developer.apple.com/documentation/macos-release-notes/macos-12_0_1-release-notes [developer.apple.com]
- https://www.macrumors.com/2022/01/28/apple-removing-python-2-in-macos-12-3/. [www.macrumors.com]
This means that there's no longer a
/usr/bin/pythoninstall bundled with Monterey 12.3+. As such, using it in a wrapper script is bound to fail.The interesting thing is that this bug happens also with the version of houdini 19 that uses python3 internally.
To reproduce this behavior, I tested different combinations (still for 19.0.561) :
- macOS build for py3
houdinifx is still a python script using #!/usr/bin/python. Tested in houdini-19.0.561-macosx_x86_64_clang11.0_10.15 - macOS build for py2
houdinifx is still a python script using #!/usr/bin/python. Tested in houdini-py2-19.0.561-macosx_x86_64_clang11.0_10.15 - linux build for py3
houdinifx is a bash script (houdini-19.0.531-linux_x86_64_gcc9.3/houdini/bin/houdinifx) - linux build for py2
houdinifx is a bash script (houdini-py2-19.0.561-linux_x86_64_gcc9.3/houdini/bin/houdinifx)
As a quick hotfix, you guys could at least fix the python3 build for 19.0.561 and make the houdinifx wrapper script use python3 instead. This build should however be marked as non compatible with Monterey 12.3+.
Of course, houdinifx can still be run directly by avoiding the python wrapper that runs houdini/houdinifx, but I believe this issue should be addressed since "by default" the "houdini terminal" workflow is not compatible with recent macOS versions.
It's worth nothing that in 19.5.303 this behavior has changed and 'houdinifx' is just a bash wrapper, so this works fine once again:
$ cd /Applications/Houdini/Houdini19.5.303/Frameworks/Houdini.framework/Versions/Current/Resources
$ which houdinifx
/Applications/Houdini/Houdini19.5.303/Frameworks/Houdini.framework/Versions/Current/Resources/bin/houdinifx
$ houdinifx
