babel + path + node 6.x: TypeError: Path must be a string. Received undefined

Question

I've been trying to update my nodejs version to 6.x but the following errors always appear everytime:

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));
    ^

TypeError: Path must be a string. Received undefined
    at assertPath (path.js:7:11)
    at Object.dirname (path.js:1326:5)

I tried with those three version:

• nodejs-6.0.0-1
• nodejs-6.2.0-1
• nodejs-6.2.1-1

in package.json: "babel-core": "^6.9.1"

I quite lost about where to start looking to debug. Anybody has a suggestion ? :) More info would be relevent ? Let me know !

Thanks in advance !

The issue has something to do with Node 6. Using Node 5.x instead will probably fix the issue for you, if that's an option.

The easiest way to do this is to install Node Version Manager (or a port for Windows), then run these commands:

nvm install 5
nvm use 5

If you want to use 5.x as your default node version, run this command:

nvm alias default 5
