Re: My pgAdmin is broken - Mailing list pgadmin-support

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
