19262	bundle_builder_toml.py should raise an error to help debug build failures	Tom Goddard	Zach Pearson	"Alexis Rohou was trying to build Clipper and an error caused it to fail but that error was suppressed and a confusing later error then made it hard to debug.  Below Tristan and Alexis figured out where the error is being suppressed and suggest it should raise an error immediately so the problem can be more easily debugged.

From Alexis:

Tristan (CCed) worked out change that revealed the actual exception. In file bundle_builder_toml.py, after line 788, he added the raises below, which revealed that the exception was due to a missing src/docs directory:


        except Exception:
            raise
            traceback.print_exc()
            return None, False
        except SystemExit:
            raise
            return None, False

Hope this helps. Tom is CCed just in case.

Cheers,
Alexis

Hi Alexis,

I have a local copy of the Clipper repo. I just pulled and tried to build it with my developer build of ChimeraX, which would have worked except I forgot to adjust the version of the ChimeraX-Core dependency.

How recent is your checkout? TOML bundle builder would throw that error if there was no version specified in the pyproject.toml file, or if you have “version” in project.dynamic and there is no __version__ in src/__init__.py (or if it’s there but it’s not the first uncommented line).
