Alternatively instead of turning  no-console  off  you can allow  In the  eslintrc js file put   rules         quot no-console quot           quot warn quot           quot allow quot     quot clear quot    quot info quot    quot error quot    quot dir quot    quot trace quot    quot log quot                This will allow you to do console log and console clear etc without throwing errors

You should update eslint config file to fix this permanently  Else you can temporarily enable or disable eslint check for console like below       eslint-disable no-console    console log someThing      eslint-enable no-console

If you just want to disable the rule once  you want to look at Exception s answer   You can improve this by only disabling the rule for one line only       on the current line   console log someThing      eslint-disable-line no-console          or on the next line      eslint-disable-next-line no-console    console log someThing

A nicer option is to make the display of console log and debugger statements conditional based on the node environment     rules           allow console and debugger in development      no-console   process env NODE ENV      production    2   0       no-debugger   process env NODE ENV      production    2   0

My 2 cents contribution  Besides removing the console warning  as shown above   it s best to remove yours logs from PROD environments  for security reasons   The best way I found to do so  is by adding this to nuxt config js   build       terser          terserOptions            compress                this removes console log from production environment           drop console  true                              How it works  Nuxt already uses terser as minifier  This config will force terser to ignore remove all console logs commands during compression

If you install eslint under your local project  you should have a directory  node modules eslint conf  and under that directory a file eslint json  You could edit the file and modify  no-console  entry with the value  off   although 0 value is supported too     rules          no-alert    off        no-array-constructor    off        no-bitwise    off        no-caller    off        no-case-declarations    error        no-catch-shadow    off        no-class-assign    error        no-cond-assign    error        no-confusing-arrow    off        no-console    off              I hope this  configuration  could help you

In package json you will find an eslintConfig line  Your  rules  line can go in there like this      eslintConfig                 extends            eslint recommended              rules            no-console    off

The following works with ESLint in VSCode if you want to disable the rule for just one line   To disable the next line      eslint-disable-next-line no-console console log  hello world      To disable the current line   console log  hello world       eslint-disable-line no-console

If you re still having trouble even after configuring your package json according to the documentation  if you ve opted to use package json to track rather than separate config files     rules            no-console    off           And it still isn t working for you  don t forget you need to go back to the command line and do npm install again
