yarn command doesn't work on Windows 10: Here's a fix.

Yarn fails with an MSBuild error: MSB4132. It is looking for v2.0 of the build tools but only v4.0 is found.

To solve this problem, you need to do a couple of things:

1. Install node’s windows-build-tools: npm install -g windows-build-tools. You will need to do this from an elevated prompt. Some Microsoft documentation on the issue says to do it from an elevated PowerShell prompt. This will take a while, so be patient.
2. Once finished, close your non-elevated terminal (if you have it open already) and re-open it.
3. From your normal user terminal (doesn’t need to be admin), set the msvs_version config setting with yarn config set msvs_version 2015. The npm command above sets it for npm but yarn needs it as well.

Once I did these things, I was able to complete the yarn command, run npm start successfully, and then see the Frontend Grocer site at http://localhost:3000/

Little update to twwilliams comment on 3 Nov 2017 for Window 10 x64 users. This steps helped me to avoid sqlite3 build:

1. Remove sqlite3 dependency from package.json.
2. Run yarn install.
3. Run yarn add sqlite3.

Now you should be able to run npm start. If you still having issues don’t forget to try node-gyp installation instructions on Windows.

Nice catch! My windows 10 must have had all of this stuff already installed. I’ll think about how to integrate this with the CLI so developers don’t have to spend time tracking this down.
