I got the problem when installing a package with resources using pysetup3.
Here's the relevant part of the console session:

writer.writerow(row)
TypeError: 'str' does not support the buffer interface
This is the relevant code in install_distinfo.run():
resources_path = os.path.join(self.distinfo_dir,
'RESOURCES')
logger.info('creating %s', resources_path)
if not self.dry_run:
#with open(resources_path, 'w', encoding='utf-8') as f:
with open(resources_path, 'wb') as f:
writer = csv.writer(f, delimiter=',',
lineterminator='\n',
quotechar='"')
for row in install_data.get_resources_out():
writer.writerow(row)
If I substitute the commented out line above which replaces 'wb' with 'w' and
encoding, I get this result:
