These are the requirements for being able to build RequestPolicy:

• Node.js (at least version 8.x)
• npm
• GNU Make
• an internet connection to be able to download Node.js packages using NPM

If you're running a Debian-based system, you may use the following instructions:

simply run sudo apt-get install make

On Debian testing (buster) or later you can simply run sudo apt-get install nodejs npm. This will install these packages:

• https://tracker.debian.org/pkg/nodejs
• https://tracker.debian.org/pkg/npm

On Debian stable (stretch) the npm package is missing, so please follow the official installation guide

Update - 25/10/2018 - NPM backporting is in progress, hopefully in a week or two.

See https://salsa.debian.org/js-team/npm/wikis/home .

So once this is done the only thing one would have to do in Debian stretch is enable backports to your hardware architecture, update the package index by running something

$ sudo apt update OR

$ sudo aptitude update OR

$ sudo apt-get update

update existing packages so there's a better migration path to Buster when it's released and can install npm when it's ready there. Nodejs can already be installed.

In general you can take a look at the columns on the left-hand side of https://tracker.debian.org/pkg/* to get a sense of the version numbers. This can be done with any debian package.

This is an optional step, but might help if you run into any issues.

Run these commands:

• node --version
• npm --version
• make --version

Example output:

$ node --version
v8.12.0
$ npm --version
6.4.1
$ make --version
GNU Make 4.1
