Windows error pack build app

[ericis]

Following the "get started" tutorial: https://buildpacks.io/docs/app-journey/

*Fresh clone of this repository today.

I've tried Windows Command Line as well as a Git Bash terminal for Windows 2.19.1.

• Windows 10 Professional
• pack version -> v0.2.0 (git sha: 6ef61143dfbc67975841c55e34ef0fceef0af88c)
• docker --version -> Docker version 18.09.2, build 6247962

What else do you need? I will also try Windows Sub-system for Linux and update this issue.

Logs

*I will submit a separate issue for the odd console output of the characters, but I think that is a bug for pack.

I used the 2nd listed buildpack (cf including python). When I switched to heroku/buildpacks it worked.
