Setuptools has removed support for 2to3 during builds since version
58[1]. But the nose's setup.py relies on use_2to3 option in setuptools,
it is failing an import and building without running 2to3 and generating
valid python3 code. As a workaround, we use command line 2to3 tool to
translate to Python3 code before build it.
Fixes:
$ python3
>>> import nose
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python3.10/site-packages/nose/_init_.py", line 1, in
from nose.core import collector, main, run, run_exit, runmodule
File "/usr/lib/python3.10/site-packages/nose/core.py", line 153
print "%s version %s" % (os.path.basename(sys.argv[0]), _version_)
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?
