How to install NodeJS LTS on Windows as a local user (without admin rights)

UPDATE 10/2018

On Node’s download page referenced in step 1. there is now a .zip archive download which contains both the nodejs executable and npm. Unpacking that to a suitable path and adding this path to your PATH environment variable (step 2.) will give you both node and npm (so you can skip steps 3. – 6.).

Let say you want to install it into %userprofile%\Applications\nodejs-lts, let’s name it <NODE_PATH>.

1. Download the LTS node.exe binary for Windows and copy it to <NODE_PATH>.

2. Add <NODE_PATH> to your PATH environment variable (set PATH=<NODE_PATH>;%PATH% or using Windows user interface)

3. Download the stable at https://registry.npmjs.org/npm/-/npm-{VERSION}.tgz npm package (following the documentation)

4. Unzip the npm-{VERSION}.tgz anywhere (using 7zip for example)

5. Launch a cmd and cd into the place where you have unzipped npm

6. Execute: node cli.js install -gf or node bin/npm-cli.js install npm -gf on certain versions (thanks to this comment)

The last command is specified in the Makefile for target install, target which the README.md invites to execute when manually installing.
