Gatsby: Example site running clarification

[orshick]

Description

I tried to run run some sites from the gatsby example section (gatsbygram and using-page-transitions). Basically I cloned the gatsby repo, npm installed inside it, entered the example site's directory and npm installed there too. "gatsby develop" errored out with this message.

Anybody have any idea why I got this? Did I just miss something about how to run the example sites?

Thanks.

Environment

Gatsby version: 1.1.41
Node.js version: 9.5.0
Operating System: Windows 10

Actual result

Error that is listed above. Site does not go into 'develop' mode.

Expected behavior

I should be able to see the site!

Steps to reproduce

1. git clone the gatsby repo, then npm -i inside of it

2. enter the example site directory, then npm -i inside of it

3. When installation is done, run 'gatsby develop'

Hey @orshick! Looks like you're missing Python. Please take a look at https://www.gatsbyjs.org/docs/gatsby-on-windows/ and let us know if that helped.
