Installing local package fails at installing npm dependency

Meteor: 1.7.0.5

I have several local packages in a packages directory in the application root. All of them works fine but one. It will not install dependencies. The package.js has this directive:

Npm.depends({
lodash:‘4.17.4’,
‘adm-zip’:‘0.4.11’
});

It says that /app/packages/decomposer/.npm/package-new-RANDOMASCII/node_modules/lodash/package.json.RANDOMNUMBERS is busy. And produces errno -26 with code ETXTBSY

I have tried many things, like close all A/V software and the likes but nothing does it… I have been struggling with this the hole day! The weirdest thing is that other local packages do use the same lodash version without any problem, but only the decomposer module is stuck…
