Error: Current platform "darwin 15" does not match expected platform "darwin 14

Question

I just upgraded my OS X from 10.10.5 to OS X El Capitan 10.11.

I tried to update my mac ports to version 2.3.3 ...

Mac ports is getting this error:

$ sudo port selfupdate
Error: Current platform "darwin 15" does not match expected platform "darwin 14

$ port -qv installed > myports.txt
Error: Current platform "darwin 15" does not match expected platform "darwin 14"
Error: If you upgraded your OS, please follow the migration instructions: https://trac.macports.org/wiki/Migration
Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch

Any ideas?

I tried following these porting instructions:

https://www.ghostwheel.com/merlin/Personal/notes/2015/09/14/installing-macports-on-os-x-10-11-el-capitan/

but the 'make' of macport 2.3.3 failed:

There is no 2.3.4 .pkg on the mac port site.

Answer 1

Error: If you upgraded your OS, please follow the migration instructions: https://trac.macports.org/wiki/Migration

EDIT: The easiest is to just download the MacPorts 2.3.4 installer for El Capitan from the MacPorts site.

Answer 2

m7thon's solution worked for me on both my iMac (Late 2013) and MacbookPro (Early 2015). Follow the link provided by m7thon:

MacPort Migration Instructions --> https://trac.macports.org/wiki/Migration.

After installing the new version of MacPorts for El Capitan, follow the instructions to 1) compile a list of your installed ports (they weren't deleted when you upgraded to El Capitan), 2) delete them, and 3) reinstall them. Make sure you install Xcode command line tools prior to steps 1 thru 3:

xcode-select --install

Depending on how many ports you have installed, Step 3 can take a few hours, so make sure you are connected to a power source. For example, it takes the better part of an hour for MacPorts to build the gcc library.
