I did it. But if you do that It insall an older version. Not the one that support that.

Check your package.json for sure you have version 2.somethig but if you run npm i fingerprintjs2 it will instal a version 1.8

I also encountered this problem and later solved it.
The reason is that the default installation is version 1.8. The 1.8 version does not support this method. See which version is in your package.json file. You need to install the latest version 2.0.
Use the command: npm install fingerprintjs2@2 --save

Looks weird, in my repo all fine 2.* version
In you case it could be related with old package-lock.json
