I am intalling Rasa X in a Python 3.7 conda environment on Windows 10. pip version is 20.3.3.
pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple
It have been going on for 5-6 hours and seems to be confused:
Any idea what I can do to fix this?
It is caused by the dependency resolution backtracking logic introduced in pip v20.3. (docs)
A fix for now is to downgrade pip to v20.2, with:
pip install --upgrade pip==20.2
Instead of downgrading pip you can also use the old dependency resolver until pip 21.0 ships (that's when they strip the old resolver from the code base), like so:
pip3 install --use-deprecated=legacy-resolver rasa-x --extra-index-url https://pypi.rasa.com/simple
After facing this issue for quite a while, I finally got if fixed after enquiring at rasa forum.
With rasa==2.7.0 and pip==20.2, I ran the command pip install rasa-x --extra-index-url https://pypi.rasa.com/simple which was quick. It installed rasa-x==0.40.1 for me.
I had the same problem, I downgraded pip to v 20.2. Then I had to download Visual Studio Build Tools 2019 and the issue is resolved.
The latest version of pip 21.3. also solves the problem. Just try and upgrade pip by using
pip install --upgrade pip
