Install dependencies causes pip to install every version of ccxt

[jhoogstraat]

When installing the dependencies using pip install -r requirements.txt every version of ccxt gets installed.

Example:

Which pip Version are you using?
And which Branch are you using (prob the ohlcv Branch)
The only similar ocurrence i found Was this: pypa/pip#9284

[jhoogstraat]

Yep, I was just testing different branches. I rebased the ohlcv branch onto main though.
I used pip 21, windows machine.

pypa/pip#9284 (comment)

It just could be that what you expirience is Not a Bug per se but a feature of pip, called backtracking.

[jhoogstraat]

The issue is that ccxt has a minimum version, while its dependencies are locked to a specific version. I think it would be better to just include the direct dependencies, like so:

ccxt>=1.76.91
python-dateutil==2.8.2
requests==2.27.1

[scientes]

yeah i need to look at the python modules some are not needed anymore i think. also i couldn't replicate your bug/feature and including the direct dependencies can lead to more issues, e.g. if ccxt updates their dependency version and we locked them pip will throw an error

[jhoogstraat]

True, that's what I meant!
There are only 3 dependencies that have to go into requirements.txt (see list above).

I close this issue, as this regarding an unfinished PR #16
