[Solved] Vue Error: error: ‘to‘ is defined but never used (no-unused-vars)

Solution 1:
Add the following code to the .eslintrc.js file.

rules: {
"no-console": "off",
"no-unused-vars": "off", // important var variables are introduced
"no-debugger": process.env.NODE_ENV === "production" ?"error" : "off",
},
