在MacOs High Sierra上出现Canopy Package Manager错误

Question

I have a problem with installing packages via the built in Package Manager of enthought Canopy. I tried to use the "Upgrade all packages", but it failed.

Beforehand, I tried to solve my problem according to this post , but it did not functionating.

The Package Manager returns with the message:

Warming up...

For me, this screen isn't informative and so I am not able to figure out how to solve this problem.

Answer 1

Please uninstall pyside, shiboken, and qt, then try again. (Pyside is already installed using qt 4, and this cannot coexist with qt 5 in the same environment.) Alternatively, you could use Canopy's integrated EDM to create a new environment with pyqt 5, so you could still use pyside / qt 4 in your original user environment and use pyqt 5 in your new environment.
