MODX 3 — can't install MIGX

Just installed the latest nightly for MODX 3 alpha 3 (Oct 26). Tried to download and install MIGX and it wouldn’t complete. Got this message:

Install failed with Error in /core/components/migx/model/migx/migxpackagemanager.class.php:3: Class ‘xPDOGenerator_mysql’ not found
Could not install package with signature: migx-2.13.0-rc1

Any ideas? Was there a new version in development for MODX 3? I can’t remember.

FYI, there was an official MODX 3 alpha 3 release on the 27th. It is slightly newer than the nightly.

MIGX is indeed not yet compatible. FWIW, I’ve emailed Bruno a few days ago offering a bounty for that as I can see this one would be a major obstacle to upgrading many sites.

Indeed, MIGX currently isn’t compatible with MODX 3, yet.
But its on my list for sure. I think, it will be a lot of work, to get everything running again.
Hadn’t much time to look any deeper into what needs to be done and will probably not till the end of the year.
Pull 355 might be a good start.
And thanks @markh for your kind offer! I really appreciate that.
Maybe there are coming some more offers or donations to get me motivated.

Thanks, downloading now.

If there’s a goal for how much you’d need, that can make crowdfunding more effective. There’s so many people relying on MIGX there surely will be others willing to pitch in.
