Comment:
I get same problem, when porting my code to python 3.
Django on python2 create migration with byte-strings in code:
{{{
apps/post/migrations/0001_initial.py: ('picture',
models.ImageField(upload_to=b'images/posts/%Y_%m/%d', null=True,
verbose_name='Picture', blank=True)),
apps/post/migrations/0001_initial.py: ('lang_code',
models.ForeignKey(default=b'en', verbose_name='Language',
to='account.Language')),
}}}
And when we run it in python3 environ it crashes.
Works for me fix:
{{{
$ find apps -type f -exec sed -i "s/{b'/{'/g" {} \;
$ find apps -type f -exec sed -i "s/(b'/('/g" {} \;
$ find apps -type f -exec sed -i "s/ b'/ '/g" {} \;
$ find apps -type f -exec sed -i "s/=b'/='/g" {} \;
$ find apps -type f -exec sed -i "s/\[b'/\['/g" {} \;
}}}
