If you have tried using npm or node installed with nvm (Node Version Manager) in cron jobs, you may have run into the infamous “node: command not found” error.
Bellow is the workaround I have been using lately:
crontab
$ crontab -e
* * * * /bin/bash /home/devimal/Desktop/demo.shdemo.sh
# Load nvm
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
nvm use 12.13.0
# now node works
node -e "console.log('hello')"
node --version
# npm works too!
npm --versionExtras
You can also make the script executable and run it ad-hoc:
Adhoc
# Make it executable
$ chmod +x /home/devimal/Desktop/demo.sh
# Run it
$ ./home/devimal/Desktop/demo.sh
