Error trying to run pgAdmin4

After following the documentation on adding PgAdmin 4 to my Fedora 28 failed in every possible way I went with the Docker option:

mkdir ~/.pgadmin4  # to store config and stuff
docker run -d --rm --network host -v ~/.pgadmin4:/pgadmin thajeztah/pgadmin4

Then go to http://localhost:5050 and you are done with it.

See https://github.com/thaJeztah/pgadmin4-docker for more info.

According to https://www.pgadmin.org/download/pip4.php.

Install the virtualenv by running:

sudo apt-get install virtualenv

You also need to install these 2 libraries:

sudo apt-get install libpq-dev python-dev 

Then:

cd ~/bin/
virtualenv pgadmin4

I prefer to use the ~/bin/ directory for installing applications.

Then you download the pgadmin4-1.1-py2-none-any.whl or pgadmin4-1.1-py3-none-any.whl depending on the python version you use. For this example we use python 2.7.

You download pgadmin4:

wget https://ftp.postgresql.org/pub/pgadmin3/pgadmin4/v1.1/pip/pgadmin4-1.1-py2-none-any.whl

Activate the virtualenv:

. ~/bin/pgadmin4/bin/activate

After that you will see (pgadmin4) in the terminal.

Inside of pgadmin4 run:

pip install ./pgadmin4-1.1-py2-none-any.whl

After that you must be able to run pgadmin4:

python ~/bin/pgadmin4/lib/python2.7/site-packages/pgadmin4/pgAdmin4.py 

In order to make the running process a bit easier you can create an alias. For instance, in Ubuntu 16.04 LTS, add alias in the ~/.bash_aliases file:

alias pgadmin4='. /home/your_username/bin/pgadmin4/bin/activate; /home/your_username/bin/pgadmin4/lib/python2.7/site-packages/pgadmin4/pgAdmin4.py'

Where your_username should be replaced by your real user name.

Then give execute permission, for example, 764 to the pgAdmin4.py file in:

/home/your_username/bin/pgadmin4/lib/python2.7/site-packages/pgadmin4/pgAdmin4.py

Also you need to edit the pgAdmin4.py file and add this line in the very top:

#!/home/your_username/bin/pgadmin4/bin/python

where your_username is your real user name.

This will make sure that you run the application using the required version of python and include all necessary dependencies in order to run pgadmin4.

Then run . ~/.bashrc in order to apply the changes.

So now you can open your terminal and simply type pgadmin4 in order to run it.

Open your browser and point to:

http://127.0.0.1:5050

One more thing to note - if you need to run pgadmin4 in desktop mode you need to change SERVER_MODE to False in:

/home/your_username/bin/pgadmin4/lib/python2.7/site-packages/pgadmin4/config.py

Otherwise when you visit localhost:5050 it will ask you for your login and password.

UDPATE:

As of 2021 (and significantly earlier) a much better option would be to use a preconfigured docker container with pgadmin4 on it. For example, a pgadmin4 docker image can be downloaded from https://hub.docker.com/r/dpage/pgadmin4/.

Hope this helps.

Please, try these commands:

sudo apt-get install pgadmin4

sudo python3.5 /usr/share/pgadmin4/web/pgAdmin4.py
