Has there been any update on this port? The new log file is attached, and it doesn't build.

[ryandesign (Ryan Carsten Schmidt)]

I see it fails with "TypeError: argument of type 'NoneType' is not iterable" when running something with "python". What is "python" on your system? You can run "command -v python" to find out where it is and "python -V" to find out what version it is. I suspect you have selected a version of python that is either too new or too old for Qt 5. The qt5-qtwebengine port should be enhanced to use a specific known-good version of MacPorts Python and not rely on the user having selected a suitable one.

It is Python 2.7.11, located at /opt/local/bin/python.

there is the code

try:
  from ply import lex
except:
  module_path, module_name = os.path.split(__file__)
  third_party = os.path.join(module_path, '..', '..', 'third_party')
  sys.path.append(third_party)
  from ply import lex

I did not have the port py27-ply installed, but you seem to.
Even after installing py27-ply, I was not able to reproduced the error.

There is a discrepancy, however, on the line numbers of the py27-ply file

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ply/lex.py

Is it possible that you are using an old version of py27-ply (r142769)?

Please look in

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ply/lex.py

The __version__ variable should say 3.8.
Is that the case?

I have version = '3.6'

I will uninstall and reinstall.

Did upgrading py27-ply fix the problem?

[jianguohsiang82@…]

Yes, uninstalling and reinstalling the port solved this problem. Please close. Thank you!

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

r145315 should ensure this does not happen again.
