I also had this problem, but the issue is some incompatibilities in
pycryptodome and pycrypto:
1. Install v3.0:
pip install ./pgadmin4-3.0-py2.py3-none-any.whl
2. Unistall pycryptodome:
pip uninstall pycryptodome
3. Uninstall/Install pgcrypto:
pip uninstall pycrypto
pip3 install pycrypto
4. Start pgadmin4:
python /usr/local/lib/python/site-packages/pgadmin4/pgAdmin4.py &
Go to: http://127.0.0.1:5050
After that v3.0 works just fine.
Cheers,
Isaias S.

A couple of days ago I tried upgrading to v3.0. This never worked for
me. Normally I activate the python environment and then install the
latest wheel file to upgrade. I was never able to login successfully
on v3.0.
So I gave up and tried to go back to v2.1, again I did so by
reinstalling the v2.1 wheel file. However afterwards I can't launch
pgAdmin. I get this error message:
alembic.util.exc.CommandError: Can't locate revision identified by
'50aad68f99c2'
I've now burned several hours on trying to fix this. What is the best
way to at least get back to a working system with v2.1? In the future
is there some better way to upgrade or revert to a previous version
when things go wrong?
Thanks, Derek
