trouble starting imgen

[leElvyn]

I installed rethinkdb, cloned the repo and used pip install requirements.txt, but when running start.sh, I get this error
Traceback (most recent call last): File "/usr/lib/python3/dist-packages/gunicorn/util.py", line 99, in load_class mod = importlib.import_module('.'.join(components)) File "/usr/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_impo rt File "<frozen importlib._bootstrap>", line 991, in _find_and_ load File "<frozen importlib._bootstrap>", line 975, in _find_and_ load_unlocked File "<frozen importlib._bootstrap>", line 671, in _load_unlo cked File "<frozen importlib._bootstrap_external>", line 783, in e xec_module File "<frozen importlib._bootstrap>", line 219, in _call_with _frames_removed File "/usr/lib/python3/dist-packages/gunicorn/workers/ggevent .py", line 16, in <module> raise RuntimeError("gevent worker requires gevent 1.4 or hi gher") RuntimeError: gevent worker requires gevent 1.4 or higher ]
Could you help me please ?
I'm running Ubuntu 20.04, and python 3.8.2

Try python 3.6

You could use pip install gevent>1.4
