If anyone has issues with target-parquet today on Linux - try pinning to v0.2.6

Hi Isobel! Would you like to share more details on the issues you encountered with target-parquet?

I believe it's this fix: https://github.com/estrategiahq/target-parquet/pull/14 I installed in a fresh project today, and started getting odd errors I hadn't seen in an example yesterday. Stack trace was very similar to those posted by people this fix was made to address:

INFO Sending version information to <http://singer.io|singer.io>. To disable sending anonymous usage data, set the config parameter "disable_collection" to true

Traceback (most recent call last):

Thanks for sharing! (So I can confirm it's kind of my fault 😂). I'm gonna have to test on linux.

Thanks for looking into it 🙂
