Github actions err: bash: line 3: npm: command not found - node.js

Question

I am trying to deploy a nodejs app from github to a remote ubuntu server via ssh. Here is my main.yml:
name: Node Github CI
on:
push:
branches:
- master
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Node Js
uses: actions/setup-node#v1
- name: SSH and deploy node app
uses: appleboy/ssh-action#master
with:
host: ${{ secrets.SERVER_IP }}
username: ${{ secrets.USERNAME }}
key: ${{ secrets.SERVER_KEY }}
script: |
service myservice stop
cd leancrm-backend
git pull git://myuser#github.com/mycmp/myapp-backend.git master
npm install
service myservice start
When I run this, I get this error:
======CMD======
service myservice stop
cd myapp-backend
git pull git://myuser#github.com/mycmp/myapp-backend.git master
npm install
service myservice start
======END======
err: fatal: Unable to look up myuser#github.com (port 9418) (Name or service not known)
err: bash: line 3: npm: command not found

Answer 1

Since you are connected to your server I assume you already have the repo there, so you only need to execute git pull.
Also you should add these lines at the beginning of the script:
export NVM_DIR=~/.nvm
source ~/.nvm/nvm.sh
My yml file looks like these at the end:
script: |
git pull
export NVM_DIR=~/.nvm
source ~/.nvm/nvm.sh
npm install
npm run start_server

Reason:
I use nvm for the server node environment, and nvm will not install the node environment in the /usr/local/bin/ directory, so that sudo can't find the corresponding instructions, and finally create a soft connection to solve
sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/node" "/usr/local/bin/node"
sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/npm" "/usr/local/bin/npm"
sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/pm2" "/usr/local/bin/pm2"
sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/yarn" "/usr/local/bin/yarn"
you can test "sudo npm -v"

Answer 3

Your first step
name: Node Js
uses: actions/setup-node#v1
sets up Node.js on the GitHub build runner. Your second step however...
name: SSH and deploy node app
uses: appleboy/ssh-action#master
with:
host: ${{ secrets.SERVER_IP }}
username: ${{ secrets.USERNAME }}
key: ${{ secrets.SERVER_KEY }}
script: |
service myservice stop
cd leancrm-backend
git pull git://myuser#github.com/mycmp/myapp-backend.git master
npm install
service myservice start
... SSHs to your server and then runs script instructions there. You're also attempting to check out your source code repo there.
What you probably wanna do is check out your repo on the GitHub build runner...
- name: Checkout repo
uses: actions/checkout#v2
.. then run npm install there, then scp the output to your server, and finally ssh to that machine and restart your service.

Answer 4

Check if you did install npm on your remote ubuntu.
npm also needs to be installed on the remote server for the deployment.
