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 => {
                   ^^

Answer 1

Your version of Node is outdated.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).
