npm install fails postinstall on Windows

[edeykholt]

When installing on Windows 10, I received this error after npm install:

3356 error code ELIFECYCLE 3357 error errno 1 3358 error [email protected] postinstall: cd rclient; npm install --no-package-lock

I adjusted package.json from: "postinstall": "cd rclient; npm install --no-package-lock", to: "postinstall": "npm install --no-package-lock rclient", and then it worked.
