Required Dependencies

There are a couple ways to install all the necessary packages. Either through a nix shell or by manually installing via the distributions package manager (likely apt)

Nix Shell Method

This is mostly recommended for getting a reproducible testing environment. The steps are as follows:

1. Install the nix package manager either for the entire system or just one user:
   • Local user: sh <(curl -L https://nixos.org/nix/install) --no-daemon
   • Local user: sh <(curl -L https://nixos.org/nix/install) --daemon
2. Update the channels via nix-channel --update
3. Enter the build environment by running nix-shell shell.nix
   • The build environment can be exited at any time by running exit
4. This should install the main dependencies. However some of the python/node libraries still need to be installed
5. For node run cd pi-src/webserver/rebuild && npm install
6. For python do the following:
   • run python -m venv ./venv
   • run source ./venv/bin/activate
   • run python -m pip install -r requirements.txt
   • Note: If adding any pip packages while in the env run pip freeze > requirements.txt

Manual method

This assumes you are using apt as the package manager. The steps are as follows: NOTE: This uses a PPA for installing linux-wifi-hotspot. The tool can alternatively be built from source if needed.

1. Run sudo apt update
2. Make sure we can install PPAs by running sudo apt install software-properties-common
3. Add required PPA sudo add-apt-repository ppa:lakinduakash/lwh
4. Run sudo apt update again
5. Run sudo apt install nodejs npm python3 python3-pip arduino linux-wifi-hotspot
6. Install the necessary python packages python3 -m pip install aiohttp aiohttp-cors
7. Make sure angular-cli is installed npm install -g @angular/cli
