py39-spyder: Runtime error

[mf2k (Frank Schima)]

$ port installed py39-spyder
The following ports are currently installed:
  py39-spyder @5.0.0_0 (active)

I get this runtime error when attempting to use it:

$ spyder

I'm still seeing this even with the new dependency installed.

are you sure it's the same RuntimeError; the change I made should have installed py-importlib_metadata so that should be present. I do see another issue now with pkg_resources.DistributionNotFound: The 'decorator<5' distribution was not found and is required by spyder-kernels.

That's probably because the py-decorator port got update to a version 5.0.6; which py-spyder-kernels doesn't like... I will take a look at that at some point. Can you please verify whether this is the issue you have now as well or if it is still related to py-importlib_metadata?

Here is what I see when attempting to run spyder:

Yes, this may be a different problem. Sorry about that.

py-spyder-kernels: remove version cap on py-decorator

Closes: #62672

[reneeotten (Renee Otten)]

okay, so I just patched out the version restriction for decorator. It says in upstream's commit message "decorator > 5 breaks cython magic`; don't know what that exactly means and spyder runs and works in my limited testing... It's not really feasible to keep track in MacPorts of the many (rather strict) version requirements spyder has; but I am hopeful that this will work out.
