Installing latest ipython release (8.24.0) causes conda validation error: 'emscripten' is not a valid Platform #927

Pinging @DerThorsten because I see that you've been working on the ipython recipe lately. Do you have any insight? |

the plattform was renamed to |

I believe everything I'm using is up to date, and I see |

can you try to use micromamba instead of conda. With micromamba you can just specify |

a
actually, the issue is in the rattler-build which writes the wrong platform to the packages. |

Terrific! Thanks so much @DerThorsten! |

For information: I just got the same error after trying to build locally JupyterLite's xeus-python-demo. First in my usual mamba forge install. After which my mambaforge got broken: any attempt to install a new package or create a new environment resulted in a `'emscripten' is not a valid Platform. I then started with a fresh Help appreciated!

Good news: upgrading conda to 24.7.1 which contains conda/conda#13962 resolved the issue! |
Hi all,
First off, thank you so much for all your work. We're using emscripten-forge in combination with voici with great success.
In the last week or two my voici builds started to fail with the error message below after the following command is executed (inside voici build).
After this error, all of my
conda installandconda createcommands start to fail (even in different environments). I tried reinstalling conda as well as updating to the latest version of conda (24.4 as of writing).Troubleshooting
I added a print line at
package_cache_data.py:123(which isself._make_single_record(base_name)according to the traceback above) and found that this validation error is triggered whenbase_name="ipython-8.24.0-py311h43c7e2a_1". That made me think that perhaps the latest emscripten-forge release of ipython is buggy so I tried pinning ipython to 8.23.0 and that fixed the issue.TLDR: Installing ipython 8.24.0 causes
conda.auxlib.exceptions.ValidationError: 'emscripten' is not a valid Platform. Installing ipython 8.23.0 works ok.Thanks in advance.
