"Plugin at index [x] does not extend Plugin." when loading Spotify plugin about erela.js HOT 2 CLOSED

This is because of transitive dependencies, if a dependency depends on package with a different version than what's in your package.json it will create a node_modules under the dependency, instanceof will not work with two different packages installed that try to use a class from it, it will reference the wrong one.

There is a temporary fix, using this package to force npm to remove transitive dependencies based on what ones you specify, if you use Yarn you will not need to install this, refer to the documentation for more.

A official fix would likely to make erela.js a development dependency so it will not install it along the others and use root node_modules, I will be fixing this soon.

@NorteX-dev Can you provide the following information relevant to your issue above? I just tried using the latest versions below and failed to reproduce the issue.

• System OS/Distro Version
• Node.js Version
• Yarn and/or NPM versions
• Erela.js Version
• Erela.js-Spotify version

You can disregard the question above. The official fix has been implemented at MenuDocs/erela.js-spotify@5b17503. If you update erela.js-spotify, these changes should be reflected.

Any future plugins should have erela.js as a development dependency so the root node_modules (the one which has erela.js installed) is used.

I will be marking this issue as closed. If any new issues arise, feel free to open a new issue.
