Rasa X install stucked

[somacruzer]

My rasa X installation has been stuck in the middle, need help! Here I am using python 3.8.5 from anaconda. Pip 21 Using mac terminal

Every time I try pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple

It would run for 10 minutes and stuck:

INFO: pip is looking at multiple versions of sniffio to determine which version is compatible with other requirements. This could take a while.

I have no idea why it is like this. Hope there can be some solutions.

Hi @somacruzer

See also this stackoverflow issue, where 2 solutions are provided:

Option 1: downgrade to pip 20:

pip install --upgrade pip==20.2

Option 2: Tell pip 21 to use the old logic:

pip install --use-deprecated=legacy-resolver rasa-x --extra-index-url https://pypi.rasa.com/simple

That’s is super useful！ Thanks you so much！

Had the same trouble, tried to migrate to poetry for package management but ended up having another problem. Since rasa x use a different source (https://pypi.rasa.com/simple) i used:

[tool.poetry.dependencies]
python = "3.7.9"
pytest = "^6.2.2"
black = "^20.8b1"
rasa = "^2.2.10"
spacy = "3.0.0"
nltk = "3.4.5"
rasa-x = {version="0.35.1", source="https://pypi.rasa.com/simple/"}

Output is:

SolverProblemError

  Because project-name depends on rasa-x (==0.35.1) which doesn't exist, version solving failed.

Any tips?

pip-20.2 works

Thank you so much! I have been struggling with this for a couple of days now and this fixed it

Thanks a lot @Arjaan!!! In my case, option 2 work:

pip install --use-deprecated=legacy-resolver rasa-x --extra-index-url https://pypi.rasa.com/simple

My python versión is 3.7.7
