Current behavior

When running npm run install:starter in Git Bash on Windows, we get the following error:

$ npm run install:starter

> stark-srcs@10.0.0-rc.3 install:starter C:\Users\superitman\DEV\stark
> cd starter && HUSKY_SKIP_INSTALL=1 && npm install && cd ..

"HUSKY_SKIP_INSTALL" is not recognized as an internal or external command,
 operable program or batch file.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Expected behavior

The command npm run install:starter should work on Linux, Mac and Windows.

Minimal reproduction of the problem with instructions

Run npm run install:starter in Git Bash on Windows.

What is the motivation / use case for changing the behavior?
