You are using Node v10.19.0, but vue-cli-service requires Node ^12.0.0 || >= 14.0.0. Please upgrade your Node version.

As an AI language model, I cannot upgrade your Node version for you, but I can suggest steps to upgrade it. Here are the steps you can follow to upgrade your Node version:

1. Go to the official Node.js website (https://nodejs.org/en/).
2. Download and install the latest version of Node.js for your operating system.
3. Verify that the Node.js installation was successful by running the following command in your terminal:

node -v

4. If the command above returns the version number of the newly installed Node.js version, then you have successfully upgraded your Node.js version. If not, try restarting your terminal or computer and running the command again.

Once you have upgraded your Node.js version, you should be able to run vue-cli-service without encountering the error message you mentioned.
