port upgrade outdated @ MacPorts 2.3.4 Error: Unable to open port: can't read "mpi.default": no such variable

[rioyokota@…]

On MacBook Air (13-inch, Early 2015), OS X 10.10.5, Xcode 7.1

After doing "sudo port selfupdate" today "sudo port upgrade outdated" returns the error "Error: Unable to open port: can't read "mpi.default": no such variable".

A quick Google search did not bring up anything useful.

Please attach the main.log file and/or indicate which port is exhibiting this problem.

[rioyokota@…]

This is not for a specific port so there is no main.log file that I can attach. The error occurs when I do "sudo port upgrade outdated".

Same thing just happened to me - it must be some change picked up with the "port selfupdate" that caused this.

It almost certainly caused by dstrubbe's change r142438.

Cc Me! I am having the same issue when upgrading gnuradio.

Same error when migrating from Yosemite to El Capitan, using restore_ports script and also when trying to install boost port manually.

Patch to fix the missing mpi.default

[ryandesign (Ryan Carsten Schmidt)]

Thanks for the patch. Looks good to me. Committed in r142448.

[dstrubbe (David Strubbe)]

Hi all, sorry about that. I built various ports using MPI in testing before committing this though, so I am confused why it worked for me without that part added in 'global' -- anyone have a thought on that?

Thanks for the quick fix!

Hey all, First time reporter here, please bear with me. My issue is identical to the OP. I see you guys have promptly released a patch to fix it fast. However being a novice, I am having trouble using the patch fix the issue. I have read the "how to" section and the 4.5 in the Macport guide. But unfortunately none of them speak about this scenario! Both those resources about fixing a specific port. Since this is not a port that is damaged here, could someone tell me how would I go about using the patch to fix the issue.

Thank you

[dstrubbe (David Strubbe)]

Just do

sudo port selfupdate
sudo port upgrade outdated

There's nothing you have to do with the patch, that is something that was committed to the repository, and there are no "releases" per se; the ports repository is continually updated.

[hosamani@…]

OK. Thank you. I realize my folly now. I was trying to upgrade the ports without updating the port tree once again after encountering the error. Looks like its all fixed now. Thank you

Thanks for the quick fix!!
