Error on node 13.5.0
https://travis-ci.com/javascript-obfuscator/javascript-obfuscator/jobs/269066094

Error: The number of constructor arguments in the derived class ObfuscationEventEmitter must be >= than the number of constructor arguments of its base class.

[sanex3339]

Should replace events module on eventemitter3 module

Got the same issue on Node.js 12.16.0. The fix works.

[PeterHdd]

Im still getting this issue

[sanex3339]

What obfuscator version are you using?

[PeterHdd]

Latest one, I just did:

npm install --save-dev javascript-obfuscator

In package.json:

    "javascript-obfuscator": "^1.1.0",

After executing javascript-obfuscator ./www, I get the error.

The error:

Error: The number of constructor arguments in the derived class t must be >= than the number of constructor arguments of its base class.

[PeterHdd]

any idea?

[sanex3339]

No. Try to completely remove your package-lock file and reinstall all packages from scratch

[sanex3339]

Also show me the output of javascript-obfuscator -v command

[sanex3339]

Any news?

[thanhpcc96]

issue too!

[sanex3339]

To everyone: try to remove package-lock.json and completely reinstall all your modules. Will it help?
This error does not reproduced on the Travis CI, so likely this is a problem related to outdated versions in package-lock.json

[sanex3339]

Did you try this?

[sanex3339]

I will close this issue. Create another one if this problem exists after removing of package-lock.json

Facing the same issue using 1.8.1 version

[sanex3339]

This error is not possible on 1.8.1 because I changed the package that was the reason for this error.
Are you sure that you're using 1.8.1?

Try to completely remove your package-lock file and reinstall all packages from scratch.
Also, show me the output of javascript-obfuscator -v command and your package.json file section with javascript-obfuscator version.

[Eljoy]

Yes, my bad. I incorrectly overrode the nested dependency javascript-obfuscator dependency for react-native-obfuscating-transformer. Is there any chance that javascript-obfuscator can be updated for react-native-obfuscating-transformer any time soon? That would be a massive help to everyone using it.

[aureliopetrone]

I get the same issue using react-native-obfuscating-transformer

[sanex3339]

As usual, try to completely remove your package-lock file and reinstall your dependencies.

Also, react native plugin is old, and you can use only obfuscator versions below 1.0.0.

[quantjamespecutus]

same issue with react-native-obfuscating-transformer here.

[sanex3339]

Same answer, try to remove package-lock.json and reinstall dependencies. This package requires obfuscator versions ^0.13.0 and above, so it should install 0.28.5 version.

Also be aware that the latest actual version is 1.11.0 and this package does not supports it. Maybe it's a time to create the fork?

[sanex3339]

@quantjamespecutus also react-native-obfuscating-transforner has issue about this problem:
javascript-obfuscator/react-native-obfuscating-transformer#35

[quantjamespecutus]

@quantjamespecutus also react-native-obfuscating-transforner has issue about this problem:
javascript-obfuscator/react-native-obfuscating-transformer#35

thanks, appreciate the help

When I use webpack-obfuscator@2.6.0, this issue shows. Can any methods to reslove it without removing yarn.lock or package-lock.json? Because after I remove it and install again, the webpack throws an error thatWebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema., it tells me that my config has some wrongs but I cant find it. I use javascript-obfuscator@latest and webpack@4.
