Conflicting dependencies at installation time #6

Closed drprojects closed 1 year ago

Hi, thanks for sharing this work !

I have been trying to pip install blendify but come across some dependency issues :

$ pip install blendify
Defaulting to user installation because normal site-packages is not writeable

ERROR: Cannot install blendify==1.2.0, blendify==1.2.1 and blendify==1.2.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    blendify 1.2.2 depends on bpy==3.5.0
    blendify 1.2.1 depends on bpy==3.5.0
    blendify 1.2.0 depends on bpy==3.5.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

It seems bpy is needed, but I could not install the seemingly-required bpy==3.5.0 version, only the 3.4.0, even though the official bpy page suggests I should be able to install 3.5.0 .

Did you come across similar installation issues ? Thanks in advance for the help !

Hi again, I managed to solve this problem. For the record, using a more recent conda=22.9.0 version and using python=3.10.9 solved the issue. Closing this issue. Cheers Damien
