What is the actual meaning of Inclusive ordered comparison in python version
I have this specified in my constraints file
asgiref==3.5.0
and when I run pip3 install during docker build, it complains about
#12 24.67 ERROR: Cannot install -r /tmp/requirements.txt (line 16) because these package versions have conflicting dependencies.
#12 24.67
#12 24.67 The conflict is caused by:
#12 24.67 django 3.2.11 depends on asgiref<4 and >=3.3.2
#12 24.67 The user requested (constraint) asgiref==3.5.0
#12 24.67
#12 24.67 To fix this you could try to:
#12 24.67 1. loosen the range of package versions you've specified
#12 24.67 2. remove package versions to allow pip attempt to solve the dependency conflict
#12 24.67
#12 24.67 ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies
Pip3 version is 21.2.4, Linux version is 18.04, Python 3.6.9
Maybe I have been misunderstanding the >=
for the whole time, I would have thought asgiref==3.5.0
would fit the asgiref<4 and >=3.3.2
condition?
The pip3 install runs fine if I specify asgiref==3.3.3
or asgiref==3.4.0
I have the 3.5.0 installed locally fine
Not sure if I should delete my question, but I think I will put an answer to it so in case someone else encountered the same problem, I believe the culprit is during docker build it cannot find the version specified:

I don't know why it can't find the version though, maybe the version is specific to the OS/Python. But I checked the pypi index it seems the version is there and not tied to a specific OS:
Regardless, the error message was a bit confusing, should have said it can't find the version instead of "conflicting version"
I have fallen on this trap twice today, first time was my bad I set a wrong version for a package. But the second time(this question) I didn't realise it's the same problem since I have the version installed locally.
