Installation failure on Debian

I am trying pgadmin4 again.

I have downloaded pgadmin4-2.0-py2.py3-none-any.whl and did the following
(following the instructions on https://www.pgadmin.org/download/pgadmin-4-python-wheel/):

$ pyvenv-3.6 pgadmin4
$ cd pgadmin4
$ . bin/activate
$ pip3 install ~Downloads/pgadmin4-2.0-py2.py3-none-any.whl
$ python lib/python3.6/site-packages/pgadmin4/pgAdmin4.py 
Traceback (most recent call last): File "lib/python3.6/site-packages/pgadmin4/pgAdmin4.py", line 55, in <module>
exec(open(file_quote(setupfile),'r').read()) File "<string>", line 46, in <module> File
"/home/js/pgadmin4/lib/python3.6/site-packages/pgadmin4/pgadmin/setup/data_directory.py",line 23, in

PermissionError: [Errno 13] Permission denied: '/var/lib/pgadmin'
