Description of the bug

With a freshly installed Ubuntu 20.04, following the steps to setup rmf-web, I found that I had to manually install a few extra packages to get api-server to work,

# source rmf
git clone https://github.com/open-rmf/rmf-web
cd rmf-web

sudo apt update && sudo apt install curl
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
source ~/.bashrc
nvm install 14
source ~/.bashrc

pip3 install pipenv
npm install -g npm@latest
source ~/.bashrc
./script/bootstrap.sh

cd packages/api-server
npm run start

I get,

> api-server@0.0.0 start
> ../../scripts/nws.sh build -d && rm -rf run && mkdir -p run && RMF_API_SERVER_CONFIG=sqlite_local_config.py pipenv run python -m api_server

sh: 1: pipenv: not found
npm ERR! Lifecycle script `start` failed with error: 
npm ERR! Error: command failed 
npm ERR!   in workspace: api-server@0.0.0 
npm ERR!   at location: /home/aaron/workspaces/ncs/ncs-rmf-web/packages/api-server

Uninstalled pipenv and installed using apt,

pip3 uninstall pipenv
sudo apt install pipenv
npm run start

I get,

> api-server@0.0.0 start
> ../../scripts/nws.sh build -d && rm -rf run && mkdir -p run && RMF_API_SERVER_CONFIG=sqlite_local_config.py pipenv run python -m api_server

Install python-is-python3,

sudo apt install python-is-python3
npm run start

After that I got missing dependencies on tortoise-orm, pydantic, fastapi, uvicorn, rx, after fixing those, npm run start works.

pip3 install tortoise-orm pydantic fastapi uvicorn rx
npm run start

Unfortunately, after messing around with virtualenv for a bit, I could not get the same behaviors any more, and it keeps complaining that tortoise-orm cannot be found. The fix was to manually install these packages into the virtual environment,

pipenv run pip3 install tortoise-orm pydantic fastapi uvicorn rx jwt socketio flask-socketio numpy pyyaml
npm run start

Some updates, I realized I needed to run

pipenv run pip3 install tortoise-orm pydantic fastapi uvicorn rx jwt socketio flask-socketio numpy pyyaml uvicorn[standard]
npm run start

with the additional uvicorn[standard] which carried the websocket libraries

Closing this as it has gone stale, as far as I know #633, is the only fix we require for fresh systems at the moment
