No remote 'conan-center' defined in remotes

I'm having problems installing pys2let on Linux - seems to be working fine on mac. Related problem to https://github.com/astro-informatics/ssht/issues/54. I've tried installing the older versions but that doesn't work either.

Hi, I recently faced the same problem and it was solved in the following way:

Check the remote list of Conan by typing: conan remote list. You will see all remote sites of your Conan. In my case, there was no site called "conan-center", so I had to manually add it. The command is: conan remote add conan-center https://conan.bintray.com True. The pip correctly installed s2let, ssht and other packages for me.

Hope this helps!

[paddyroddy]

@tianshu-wang this worked! The problem I was having was on my CI on GitHub Actions, so I've taken pyssht and pys2let out of the requirements.txt for now and separately installed conan first i.e.

            - name: Setup conda
              uses: conda-incubator/setup-miniconda@v2
              with:
                  activate-environment: py39
                  channel-priority: strict
                  environment-file: environment.yml
                  use-only-tar-bz2: true

            - name: Fix conan problems
              run: |
                pip install conan==1.40.2
                conan remote add conan-center https://conan.bintray.com True
                pip install pys2let==2.2.3 pyssht==1.5.0

Thanks for the advise @tianshu-wang.

@paddyroddy Would you recomment we make any updates about this (e.g. to documentation)? If not can we close?

[paddyroddy]

The fix from @tianshu-wang feels like a temporary fix to me. This only started happening recently, so I feel @mdavezac /someone needs to fix something somewhere.

From my CI runs, I know that it was working without this workaround on 5th September, and that it was broken on 14th September. Obviously something happened in the meantime.

I've not noticed this problem on Mac. My CI is on Linux, so either GitHub Actions changed in that gap or conan or something else

[mdavezac]

I'll try and take a look asap. Meanwhile: https://docs.conan.io/en/latest/uploading_packages/remotes.html#conan-center-deprecated vs https://docs.conan.io/en/latest/uploading_packages/remotes.html#conancenter

[mdavezac]

A new version pointing to conancenter should land on pypi very soon.

[paddyroddy]

how soon is soon? Don't see it up yet

[mdavezac]

Please see astro-informatics/src_flag#1. I think it should resolve your problem if you are compiling src_flag by hand.
