local install / no admin rights / sls run fails because it tries a global install of the emulator

[aheissenberger]

I am using "serverless" installed local with the project and would like to do this with the emulator too.
But whenever I call ../../node_modules/.bin/sls run (serverless/serverless#4034 (comment)) it tries to do a global install and fails on my system as I do not have admin rights:

$ ../../node_modules/.bin/sls run

is there a way to install the emulator once (as sudo / root), then go about testing as non-root? I'm having the same problem.

I've run into this issue as well and am hoping for suggestions to work around the problem. NVM?
