Installing OpenFL from develop doesn't work

[DL8]

Describe the bug
fx command fails with the following after installing OpenFL from repo:

$ fx
Traceback (most recent call last):
  File "/home/vmuser/venv_test/bin/fx", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/home/vmuser/venv_test/lib/python3.8/site-packages/pkg_resources/__init__.py", line 3252, in <module>
    def _initialize_master_working_set():

    needed = self.resolve(parse_requirements(requirements))
  File "/home/vmuser/venv_test/lib/python3.8/site-packages/pkg_resources/__init__.py", line 786, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'jsonpointer>1.13; extra == "format-nongpl"' distribution was not found and is required by jsonschema

A second installation on the same environment fixes this issue, but it's not very elegant to demand invoking pip install twice

To Reproduce

python -m venv venv_test
. venv_test/bin/activate
git clone https://github.com/intel/openfl.git
pip install ./openfl
fx

Expected behavior
fx runs without dependency errors

Could you mention the pip version?
Besides, it is generally recommended to upgrade pip, setuptools and wheel before installing packages in a new virtual environment.
You may give this a try (in a fresh venv):

python -m venv venv_test
. venv_test/bin/activate
# Upgrade base package helpers
python -m pip install -U pip setuptools wheel
git clone https://github.com/intel/openfl.git
pip install ./openfl
fx

Python version:

$ python --version
Python 3.8.10

Pip version (from system):

$ pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

Pip version (after upgrade in the venv):

$ pip --version
pip 22.3.1 from /home/vmuser/venv_test/lib/python3.8/site-packages/pip (python 3.8)

I tried the flow you suggested and it worked. I believe this recommendation should be added to the documentation

Glad to know it worked. We'll include this in our documentation for clarity.
