Try using the below command from your project folder:

npm audit fix

If it still shows it has fixed only few of the vulnerabilities, then use the below command

npm audit fix --force

Solution 2

This warning told everything:

Unsupported platform for [email protected]: **wanted** {"os":"darwin","arch":"any"} (**current**: {"os":"win32","arch":"x64"})

Only unix-based systems use fsevents, and You are using Windows!

I know that only unix-based systems are supported but I don't need the warning in all my builds. Do you know a way on windows to get rid of this warning?
