py35-spyder-devel @3.0.0b2 +qt5 won't load after update to Qt5.6

[randawg]

I've recently upgraded my Qt and PyQt from 5.5 to 5.6, and Spyder3.0.0beta2+qt5 will no longer load but exits with the following error:

Traceback (most recent call last):

I deactivated Qt/PyQt5.6 and went back to 5.5.1_1, and Spyder3+Qt5 works just fine again, so it appears that this is some sort of incompatibility with Qt5.6. This only affects the +qt5 variant, as the regular qt4 version also loads without issue. I'm on Yosemite with xcode 7.2.1.

In the future, please Cc the port maintainers (port info --maintainers py35-spyder-devel), if any.

Upstream is aware. Fixes will arrive in b3.

​https://github.com/spyder-ide/spyder/issues/3145.

Fix is to revert to PyQt5.5 (5.5.1_1) for now. I'll close this issue once new upstream beta is available.

Hi @eborisch, I saw that upstream has fixed this.

Can you integrate it on MacPorts?

[eborisch (Eric A. Borisch)]

py-spyder-devel has been updated to 3.0.2; are you still having issues?

[mf2k (Frank Schima)]

py-spyder-devel is up to version 3.1.4. I see no problems with qt5.
