Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/esmvalcore) and found some lint.

Here's what I've got...

For recipes/esmvalcore:

• noarch: python recipes are required to have a lower bound on the python version. Typically this means putting python >=3.6 in both host and run but you should check upstream for the package's Python compatibility.

For recipes/esmvalcore:

• requirements: host: python >= 3.6 should not contain a space between relational operator and the version, i.e. python >=3.6
• requirements: run: python >= 3.6 should not contain a space between relational operator and the version, i.e. python >=3.6

@bouweandela, @valeriupredoi I created this conda-forge version of esmvalcore. As you can see, it builds for Linux, but not for win nor osx. I think windows is unattainable at the moment. Do we provide/expect an osx build?

[valeriupredoi]

@zklaus that's very cool! No need to build the package in OSX, it installs well from conda using the Linux noarch one, see our GA tests - the Win one is all smoke and mirrors so really no support for that 👍

hey @zklaus awesome job on the OSX recipe, mate! The tests are dying on OSX because of this issue and fix ESMValGroup/ESMValCore#1003 - if we fix it that way in ESMValTool too they won't fail no more
