flow-bin NPM package not finding binary on Windows?

[Daniel15]

I'm trying to configure a Windows AppVeyor build for Jest, but it's resulting in the following error while running npm install:

> [email protected] postinstall C:\projects\jest\node_modules\flow-bin
> node lib/install.js
  × No binary found matching your system. It's probably not supported.
  × flow binary test failed

My understanding is that Flow v0.30 adds support for Windows, so this should be working now, right?

Flow requires a 64-bit version of Node to be running. Needed to update the AppVeyor config to use 64-bit Node.js:

environment:
  matrix:
    - nodejs_version: "4"
    - nodejs_version: "6"

install:
  - ps: Install-Product node $env:nodejs_version x64

That's weird, probably flow-bin incorrectly assumes that if node is 32 bit, than OS is 32 bit too

Yeah, bin-wrapper (which flow-bin uses) makes that faulty assumption. Filed a task at kevva/bin-wrapper#48
