node typings Unexpected token =>

Question

I'm new to nodejs and try to install typings globally to make intellisense available for a few modules by using

npm install -g typings

After this command I try to use:

typings search tape

which gives me

C:\Users\x\AppData\Roaming\npm\node_modules\typings\node_modules\typings-core\node_modules\strip-bom\index.js:2
module.exports = x => {
                   ^^

Your version of Node is outdated. The module you are trying to load uses arrow functions, which is a syntax that was first partially introduced in Node v4.0.

Note that Node v0.12 went out of long-term support in December 2016, so is no longer supported at all. In addition, many Node modules require Node v4.0 or later, exactly because this version introduced a lot of new features that are not available in earlier versions.

I would recommend that you upgrade to Node v6.9 (current LTS version) or Node v7.4 (current stable version).

Our corporate PCs have this version installed so it's not possible for me to upgrade it unfortunately. I will try to install older version of typings then. Or try to use tsd maybe.., — yakya, Jan 28 '17 at 14:33
