Limit pytest version to <3.2.0 - #222

not sure what goes wrong for appveyor, @astrofrog can you spot a typo?

I'm really out of ideas here, powershell just hates me. @astrofrog @MSeifert04 any ideas how could this be done for appveyor?

I'm not sure what you want but Write-Host doesn't return anything (just prints to console). Also OutFile clobbers the whole file.

If you just want to create a new file that contains pytest <3.2 (+newline) just use

"pytest <3.2" | Out-File path_to_file

@MSeifert04 - Thanks. My last commit was a bit misleading, I kept amending my trials, I've started off without the pin file to have the limitation in the conda install line (weirdly it didn't work for py2.7, but was fine for the first build for 3.6), then tried all sorts of quoting, echo, etc, then remembered that powershell is a beast and has a few specific command...

as long as it works 👍 :)

yes, it's a shame to do it this way but I'm not willing to properly dig into and learn the mess of powershell 😉

Hmm, it didn't work and now I'm back at the same pit I was yesterday with those weird characters

Ah, that's just some encoding issue, you could use "pytest <3.2" | Out-File ... -Encoding ASCII.

At the end I used the super ugly hack of copying over a canned version of that file from here. There are no words to describe how much I dislike powershell.
