An unexpected error has occurred. Conda has prepared the above report.

which is strange since there is no package in that environment with which cfgrib could conflict.

Update: fixed by upgrading conda to 4.9.2

alexamici commented 3 years ago

Note that the only supported install procedure with conda is via conda-forge with the command line:

conda install -c conda-forge cfgrib

as per https://github.com/ecmwf/cfgrib#installation

jsillin commented 3 years ago

Thanks for that heads-up! Interestingly, conda install cfgrib eccodes worked on conda 4.9.2. At least nothing has broken yet haha
