installed py39-spyder attempted to start spyder which failed with following:

During handling of the above exception, another exception occurred:

Note the "...Requirement.parse('jupyter-client>=7.1.0')..."

and the "...'jupyter-client>=7.1.0' distribution was not found and is required by spyder-kernels"

for macport version 2.7.1 the highest version of jupyter-client appears to be 6.1.12

Not sure if following tickets are relevant to this or not, but just in case:

#64446

#64139

Recommendation from #64446 was to install nodejs14 vice nodejs16 in order to get qt5-qtwebengine to install . . . which I did and resulted in successful install of all dependencies for py39-spyder

[reneeotten (Renee Otten)]

thanks for the report @wcvinyard, none of the tickets you mention are relevant here. The issue -as the error message- clearly states is that py-spyder-kernels requires a newer of py-jupyter_client than is currently available in MacPorts.

@Andrew: is there a reason for not updating the port other than "I haven't had time for it yet". I am happy to take a look at it, but if would be good to know if there is an (obvious) reason not to do so.
