Mac OS Catalina

tried: sudo port -f uninstall gperf sudo port -v install gperf

--> Error: Requested variants "" do not match those the build was started with: "+universal".

For future reference, WikiFormatting makes the report much easier to read.

I am not sure how the variant +universal was added, but there is ​no reason for it.
All ​32-bit support was dropped in macOS 10.15 Catalina.
Please try

sudo port clean gperf
sudo port selfupdate
sudo port -v install gperf

the only reason your steps failed was that you had to clean out your failed universal build attempt before installing again.

Which is why I think cleaning should be automatic for all builds by default, and only turned off by devs.

This recipe worked: sudo port clean gperf sudo port selfupdate sudo port -v install gperf Thanks. I guess this can be closed. But automatic cleaning sounds like a good idea.

[kencu (Ken)]

I suppose the reason we don't auto-clean is because the logs would be cleaned as well.

Anyway, always ways to improve MacPorts....
