flask-restplus requires pyrsistent, which requires Python '>=3.5'

mh0815 commented 3 years ago

Hi, I have solved most dependency problems myself / with the help of the issues discussions here. But I don't know how to solve this one: When I install flask-restplus, it has a dependency to pyrsistent (>=0.14.0). So it downloads latest version (0.17.2), which is not running on python 2.7. So I installed pyrsistent 0.16.0, which would satisfy the requirement and run on python 2.7. But when I install flask-restplus using sudo pip install 'flask-restplus==0.12.1' it ignores the latest version and still downloads the latest version - which fails due to python 2.7. Is there a way I can modify the flask-restplus requirements to pyrsistent>=0.14.0 <=0.16.0 ?

The workaround from @schweizschweiz mentioned in issue #160 (uncommenting web api use in wordclock.py) works to start without errors, but actually I think the web interface is one of the coolest features in this wordclock - to get rid of the buttons.

Would it help to have the clock run on Python 3? I'm currently in the process of doing that. Most of the plugins compile (not physically tested though), including the web interface.

clean install stretch
first install pyrsistent (0.14.7)
than all of the rest. worked for me.

Unfortunately I seem to have the exact same problem. I did try the suggestion @Sofradex gave us with the clean install, but when trying to install flask-restplus, it always ends with the following:

Collecting pyrsistent>=0.14.0 (from jsonschema->flask-restplus) Downloading https://files.pythonhosted.org/packages/7d/ae/90ddcf28fb8eee5d4990920586d2856342e42faa95f39223f0b9762ef264/pyrsistent-0.17.2.tar.gz (106kB) 100% |████████████████████████████████| 112kB 2.0MB/s pyrsistent requires Python '>=3.5' but the running Python is 2.7.13

I tried a clean install of Stretch 2 times and installed Pyrsistent before te rest, but with nu luck.

Any way to keep flask-restplus from trying to install a newer Pyrsistent version?

edit: After checking this post, I decided to give it a final try. Again completely fresh installed the SD and installed everything. The suggested "pyrsistent==0.14.7" threw a new error, so I tried different versions in the 14.x range and 0.14.11 finally did the trick! It is a miracle !!! After that I was able to install the suggested 'flask-restplus==0.12.1'.

I hope this helps someone encountering the same issue. I think I did the whole SD installation already 6 times.

Try updating to pyhton3 and use a actual raspberry os.

Further information how to do that you can find here:

Thank you for your reply @phenze, but actually that's how I initially started. I installed the latest Raspberry OS and Python3, but I ran into issues when I followed the software setup guide. If I remember correctly, I had issues with a lot of packages, including netifaces. After reading comments like "wordclock doesn't run on python 3, you need python 2.7" I re-installed everything using the latest Raspbian Stretch and Python 2.7.

But do I understand from your post @phenze that I can actually use Raspberry OS with Python 3? How can I install all the required packages for this version?

phenze commented 3 years ago

Yes i am using latest raspberry os with python3.

Take a look here: https://github.com/phenze/rpi_wordclock/tree/master-python3

There is a Python3 Section with install instructions in the readme file

InnerChimp commented 3 years ago

Thank you very much. I will definitely try this!

HeerNMeester commented 3 years ago

@InnerChimp , Definitely do that! I reinstalled my clock last wednesday and after 3 hours of trouble with the P2.7 version I switched to @phenze's version on P3 and got it running at the first try.

Thanks again @phenze and sorry for not coming back earlier, but I guess life happened. Resulting in all the elements laying around, waiting for me to finish the project. So I started earlier this weekend and hooked everything up, but unfortunately it doesn't seem to run. I followed the Python3 section and it seemed to install fine.

When trying to run it, command line gives me the following:
