Can you provide an installation log file that shows what went wrong?

Go through the installation again. If it fails again, from the Window menu, choose Installer Log. Click Save in that window, save the log to a file, and attach it to this ticket.

The part where it says

An error occurred while extracting files from the package “MacPorts-2.6.3-10.12-Sierra.pkg”.

cpio read error: bad file format

makes me think that you have a corrupted download. Would you try deleting MacPorts-2.6.3-10.12-Sierra.pkg and downloading a fresh copy from

I did what you said but installer returns the same error as before.

The pkg is signed, so Installer would fail to verify the signature right at the start if it had been modified.

i moved the download file to different location (from downloads folder to desktop) and the installer was writing packages but stuck for too long hour and i force quit it.

After reboot, re-download the installer, moving it to desktop and run it from there, installer completed successfully. I am not sure which was the problem exactly (corrupt download/execution location of installer) but I report the steps I took if someone is facing the same problem in the future.

Thank you Joshua Root for you help and your time.

Glad you got it working. The only other suggestion I could think of was that maybe there is something wrong with your disk; you might want to open Disk Utility and run First Aid just to make sure.

I have been able to reproduce this problem trying to install MacPorts-2.6.3-10.12-Sierra.pkg onto macOS 10.12.6 with Xcode 9.3 with CLT. I tried a few times from ~/Downloads and then ~/Desktop. Same problem every time. I have just run First Aid and found 0 errors.

This is now FYI

I have now performed a Git Install, which worked fine and I'm up and running.
