Re: My pgAdmin is broken

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.
