Buffalo build fails on Windows

[hdm]

Description

The buffalo build command fails on Windows. It succeeds when GOOS=linux is set or when run on a Linux system.

Steps to Reproduce the Problem

1. Create a new buffalo application on Windows.

2. Run buffalo build -o t.exe

3. Notice an error like the following:

# With vendor/
$ buffalo build -o t.exe
a\a-packr.go:8:8: cannot find package "." in:
        C:\Users\Developer\go\project\vendor\myproject\packrd

# Without vendor/
$ buffalo build -o t.exe
a\a-packr.go:8:8: package myproject/packrd is not in GOROOT (c:\go\src\myproject\packrd)

Expected Behavior

A successful build, as seen with GOOS=linux

Actual Behavior

Ugly packr error, hard to debug as well.

I stumbled in the same issue. In my case, the latest version of packr2 was the reason for the failure. Using the v2.7.1. version fixed the problem for me.

Moving this one to Packr. thanks for reporting it @hdm
