Error trying to run pgAdmin4

I've installed postgresql 9.6 (using suggested linux installer) which comes with pgAdmin4, but getting a few errors.

First, I had to change the folder name from "pgAdmin 4" (note the extra space) to "pgAdmin4" to avoid "file not found error".

Then I run sudo python and got the following error:

Traceback (most recent call last):
   File "../../", line 24, in <module>
      from pgadmin import create_app
   File "/opt/PostgreSQL/9.6/pgAdmin4/web/pgadmin/", line 17, in <module>
      from flask import Flask, abort, request, current_app
ImportError: No module named flask

I tried following this related question: Flask ImportError: No Module Named Flask -- managed to installed flask on virtualenv.

But then I started getting other flask related modules that are missing: flask_babel, flask_login, flask_security. I installed all of them using pip, but then I got an error on missing module htmlmin.minify which I can't seems to able to install.

Traceback (most recent call last):
   File "../", line 24, in <module>
      from pgadmin import create_app
   File "/opt/PostgreSQL/9.6/pgAdmin4/web/pgadmin/", line 23, in <module>
      from htmlmin.minify import html_minify
ImportError: No module named htmlmin.minify

I also exported PYTHONPATH to the one on flask, as described here, still getting the same error.

So, anyone have an idea how to make pgAdmin4 work on ubuntu environemt?

According to

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.

Then 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 


mkdir pgadmin4
cd pgadmin4

Run the virtualenv inside of pgadmin4:

virtualenv venv

Activate the virtualenv:

. venv/bin/activate

After that you will see (venv) 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 (according to the official website. I haven't tested it personally):

python ~/pgadmin4/lib/python2.7/site-packages/pgadmin4/ (probably this path needs to be corrected)

Open your browser and point to:

Hope this helps.
