[Install] --process-dependency-links removed in pip >= 19.0

[ImreSamu]

Current recomended installing: sudo pip install -r requirements.txt --process-dependency-links .

but now:
pip 19.0 (2019-01-22)

• "Remove the deprecated --process-dependency-links option."

workarounds:

• Un-deprecate --process-dependency-links until an alternative is implemented pypa/pip#4187 (comment)
• don't upgrade pip

Thanks for the notes, @ImreSamu. I ran into this issue recently:

sudo pip install -r requirements.txt --process-dependency-links .
> Usage: pip install [OPTIONS] PACKAGE_NAMES...
> no such option: --process-dependency-links

In case others also run into this issue, my temporary solution was to downgrade my pip version. I followed steps here: https://pip.pypa.io/en/stable/installing/

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py pip==18.0
sudo python get-pip.py pip==18.0

This solved the issue and I was able to successfully run:

sudo pip install -r requirements.txt --process-dependency-links .

My comment above works fine in Python2, but will not work if you're using Python3 (you'll likely see a VersionConflict error if you downgrade).

@ImreSamu - what has been your workaround? Fiddling with the requirements.txt and setup.py files mentioned in pypa/pip#4187 (comment)?

Thanks @ImreSamu

For now, this can installed with newer pip versions by simply using:

sudo pip install -r requirements.txt .
