py27-spyder upgrade error

[dershow]

I just attempted to upgrade py27-spyder from 2.3.8_0 to 3.2.8_0. That triggered a bunch of upgrades, including py27-pyqt5, that seemed to go fine. But, then when it got to the actual build of spyder I got this error:

The solution was to manually change the variant of py27-pyqt5

sudo port install py27-pyqt5 +webengine

Then, I was able to get the spyder upgrade to run properly.

thanks for the report. There is, however, not much that can be done about this - at least as far as I know. The require_active_variants py${python.version}-pyqt5 webengine is used to specify that pyqt5 needs to be installed with the webengine variant, but this cannot be enforced automatically during the install so it's up to the user to do so.

Unfortunately there is no facility (unless it's new and I missed it) in MacPorts to ensure that a dependency has been installed with particular variant beyond the technique already in place here.
