Install from sources fails

Hi,

I’ve tried to install from sources today from sources so

git clone https://github.com/jean-emmanuel/open-stage-control
cd open-stage-control/
# uncomment next line if you want the latest release
# instead of the current development version
# git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
npm install

and then c’est le drame

npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'open',
npm ERR!   path:
npm ERR!    '/home/nlb/.npm/_cacache/index-v5/fb/76/ea4ff78e14fb6a87ef53e75f7b783fc2568cca5e8cf321c6b3d2f627ebb0',
npm ERR!   parent: 'open-stage-control' }
npm ERR!

Strange non ?

It’s related to npm itself : https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

ok but it’s odd because i do install others softwares and with npm install and no problem.
