SyntaxError: Missing parentheses in call to 'print' when running on Python3

[marcomc]

The requirements say Python 3.6.0 is required
but in reality, it looks like the code has been written with Python2 standards
in fact if I run the application with Python 3.x it fails as follow:

python /usr/local/bin/macprefs restore
  File "/usr/local/bin/macprefs", line 23
    print 'Backup Complete.'
                           ^
SyntaxError: Missing parentheses in call to 'print'

if I run it in Python 2 it works fine

are you planning to adapt the code?

The README does claim python 3.6 is required, is that not accurate? Having this issue as well.

@clintmod any guidance here? I'm having the same issue

$ python --version
Python 3.9.7
$ macprefs backup
  File "/usr/local/bin/macprefs", line 23
    print 'Backup Complete.'
          ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('Backup Complete.')?

But when I uninstall python3, I get this

$ python --version
Python 2.7.16
$ macprefs backup

Use python 2.x

Ya sorry it's python 2.

[Bobronium]

I was able to get it working with python 3 by converting it with 2to3 tool and changing one line:

entrypoint=$(readlink -f $(which macprefs)) \
    && sudo 2to3 -W -n $entrypoint $(dirname $entrypoint) \
    && before=$(cat $entrypoint) \
    && sed 's/== "None"/is None/' $entrypoint | sudo tee $entrypoint | diff <(echo $before) -

Works:

macprefs
macprefs --help
macprefs --version
macprefs backup

Doesn't work:

macprefs --verbose backup  # UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2 in position 382: invalid continuation byte

Haven't tried:

macprefs restore
macprefs --verbose restore 

I got the same error, How do i resolve this. Please help

Permission issue, try sudo macprefs backup

The key point is to use python2 instead of python3. In addition to the 2to3 tool, maybe it is more convenient to use pyenv to set the python version to python2.
