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

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

[xhochy]

Awesome, we can at least replicate it.

@conda-forge/pypy3-6 @isuruf This is ready for review&merge.

I reopened the PyPy issue around this. Is is conda-specific or should PyPy be doing something different on windows? https://foss.heptapod.net/pypy/pypy/-/issues/3653

Ahh, I see CPython has a similar patch https://github.com/conda-forge/python-feedstock/blob/main/recipe/patches/0010-Fix-TZPATH-on-windows.patch

The bug was introduced in PyPy once PyPy synced the respective module from CPython. Thus having the same patch on both sides is the most logical path.
