Can't update Macports (with Mac OS X Mavericks)

Question

After upgrading Mac OS X to newest version Mavericks, I attempted to selfupdate my Macports, but it failed:

$ sudo port -v selfupdate
--->  Updating MacPo         


        

Answer 1

I had this issue on Mountain Lion and it was actually to do with MacPorts looking at an old XCode path (I had several versions including betas installed). I ran with the -d option and checked the config.log file at /opt/local/var/macports/sources/rsync.macports.org/release/base and it reported some errors:-

--- snip ---
...
configure:3331: checking for C compiler version
configure:3340: gcc --version >&5
Configured with: --prefix=/Applications/Xcode5-DP3.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
xcrun: Error: could not stat active Xcode path '/Applications/Xcode5-DP3.app/Contents/Developer'. (No such file or directory)
configure:3351: $? = 0
configure:3340: gcc -v >&5
Configured with: --prefix=/Applications/Xcode5-DP3.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
xcrun: Error: could not stat active Xcode path '/Applications/Xcode5-DP3.app/Contents/Developer'. (No such file or directory)
...
--- snip ---

So I gave it the correct path using:-

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

and that fixed it.

I got my clues from this useful page.

Answer 2

I got an error with selfupdate, and resolved it by doing a fresh installation of MacPorts from http://www.macports.org/install.php. Now I can run the selfupdate command without error and install other ports.

The error I were seeing was below, it seems the same problem as Yo Sophia has pointed out:

$ sudo port selfupdate
Password:
--->  Updating MacPorts base sources using rsync
MacPorts base version 2.1.3 installed,
MacPorts base version 2.2.1 downloaded.
--->  Updating the ports tree
--->  MacPorts base is outdated, installing new version 2.2.1
Installing new MacPorts release in /opt/local as root:admin; permissions 0755; Tcl-Package in /Library/Tcl

Error: /opt/local/bin/port: port selfupdate failed: Error installing new MacPorts base: command execution failed

Answer 3

The problem seems to be with Macports and the location of the Tcl framework and it's path once Xcode has been installed. I suggest installing a fresh version of Macports for Mavericks here : http://www.macports.org/install.php.
