@vue/cli-servicepackage is missing from your project dependencies. - An outdated version of Node.js or npm is causing compatibility issues.

Solutions
1. Reinstall Vue CLI
To ensure Vue CLI is installed correctly, reinstall it globally using the following command:
npm uninstall -g @vue/cli
npm install -g @vue/cli
After reinstalling, check if the 'vue-cli-service' command is available:
vue --version
If it still doesn't work, try the next solution.
2. Check Package Dependencies
Make sure the @vue/cli-service package is listed in your project's package.json file under the dependencies or devDependencies section. If it's missing, install it locally using the following command:
npm install --save-dev @vue/cli-service
Now try running the 'vue-cli-service' command again.
3. Update Node.js and npm
Outdated versions of Node.js and npm can cause compatibility issues. Update them to the latest stable versions using the following commands:
npm install -g n
sudo n stable
To update npm, run:
npm install -g npm@latest
Now, try running the 'vue-cli-service' command again.
4. Use npx or yarn
If the error persists, try using npx or yarn to run the 'vue-cli-service' command. If you don't have yarn installed, you can install it using:
