TST: Install pytz in the CI.

[jakirkham]

Fixes: #7335
Related: #7336

This should allow for some tests that require pytz to run during CI.

May be worth backporting this to 1.11.x as well just to make sure we have fixed any silent failures. Then again, I think there was only one and we are planning on explicitly silencing it anyways.

Should it be installed on appveyor too? (I don't have an opinion but figure the question should be raised :-))

[jakirkham]

I was thinking it when I opened the PR. I will add it.

[jakirkham]

Added to both.

[jakirkham]

Are there any other cases like these that you know of?

[njsmith]

Not I. I guess you could grep through the skipped and known failure tests.

LGTM, feel free to merge once CI tests pass.

[njsmith]

Umm, if you have commit access, I mean. I forgot you might not :-)

[jakirkham]

Looks like git grep agrees with you.

I was going to ask if that was more a general comment or if you were meaning I should. Yeah, I don't.

Weird, appears to be some issue with this new setuptools package in conda. I experienced the same problem locally (on Mac) when I tried to update earlier so it is not Windows specific. Added this issue. ( conda/conda#2127 ) Will see what they have to say.

Thanks @jakirkham .

[jakirkham]

Of course.

I am going to add a backport PR for 1.11.x not that I think there will be any more problems, but just to make sure.

[jakirkham]

Added the backport PR ( #7343 ).
