Module version mismatch. Expected 46, got 48.

I'm having this error on Node v.4.4.7:

module.js:434
  return process.dlopen(module, path._makeLong(filename));
                 ^

Error: Module version mismatch. Expected 46, got 48.

Hi, Looks like you compiled the module in a different version than the one you want to execute it.

Seems that installing with sudo or --unsafe-perm give this kind of error

Check which node version you have in each environment. I had the issue with running Node on Docker with a different version than on the host, while mounting the filesystem for debugging => I was running inside container with node version X while module module was compiled in node version Y on the host.

@roccomuso Could you confirm your node, npm and node-gyp versions?

node -v
npm-v
node-gyp -v

[roccomuso]

Node: v4.4.0 Npm: v2.14.20 Node-gyp: (not globally installed, guess I'm using the one coming with node v4.4.0)

Trying to install with root privilege return this:

gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/4.4.0"
