I used to use spyder, installed via the ArcPro Python package manager, on a former computer. Now on a new computer, after the initial clone>install spyder>launch spyder process, I cannot for the life of me quit getting an internal error message from spyder.
I'm using ArcPro 2.9.
uninstall spyder via the package manager
you have to install spyder via conda in your cloned environment, so make it active first
>>> activate .....
>>> conda install spyder=5.1.5
dont upgrade to a higher version using pip because there are a number of other issues too many to go into here
I had done a couple iterations of uninstall, reinstall, with varying methods of using the package manager vs conda in the command prompt. Wasn't really sure what I did different but finally on a reinstall it seemed I actually got the correct version of spyder installed and it finally worked. thank you!
