fail to install basemap in Win11 with the newest python 3.11 #561

Closed Fox-0124 closed 2 years ago

Fox-0124 commented 2 years ago

When I install basemap with 'pip install basemap' or 'python -m pip install basemap', an error occurs: image

No other python versions exist in my computer.

Hi @Fox-0124! Python 3.11 is relatively new, right? You are being caught by the upper pin "<3.11" in the setup.py file. Very likely it will be enough if I increase this upper pin and rebuild the wheels also for Python 3.11.

molinav commented 2 years ago

I was checking a bit further and actually basemap pins to <4 as upper bound. The <3.11 upper bound issue is coming from the build requirement numpy==1.21.4, because the numpy versions 1.21.2 to 1.21.6 added this upper bound (not present in numpy 1.20.x, 1.22.x or 1.23.x, for example).

@Fox-0124 In the end, adding the Python 3.11 support had a bit more work than expected, but the core functionality is merged into the hotfix-1.3.6 branch. Currently, I am about to merge another Windows-related bugfix into hotfix-1.3.6.

When this is done, may I ask you to try out the first "pre-official" Python 3.11 wheel? Are you using Windows with Python 64-bit?

Once this issue can be closed, the hotfix-1.3.6 branch will be finished and I will tag a new basemap hotfix release (1.3.6).

I attach you here the hotfix candidate for Windows Python 64-bit: basemap-1.3.6-cp311-cp311-win_amd64.zip

You need to change the .zip extension with .whl, otherwise I could not attach the file in the message. I made some basic tests in my computer and it seems to work. Any feedback is appreciated, I will probably release by end of the day.

Dear @molinav , many thanks for your work. Now I success to install basemap in my computer.

molinav commented 2 years ago

Great to hear that! Then I will close this issue as completed.
