error TS6200: Definitions of the following identifiers conflict with those in another file

[C-o-d-e-C-o-w-b-o-y]

Having trouble running tsc on the basic examples shown in in the README

Versions:

{
    "@metaplex-foundation/js": "^0.11.7",
    "@solana/web3.js": "^1.47.3",
}

Any ideas?

Sadly, node_modules in nested dependencies are not de-duplicated and so TS may end up thinking they are different packages with conflicting types.

I'm hoping I can find a better way to handle this in the future but for now, the SDK fixes this by using "skipLibCheck": true on the tsconfig.json file. I feel confident this would fix your issue too.

Hi there 👋

I'm going to close this due to inactivity but feel free to open a new issue with updated information if you need to.

Thank you for your understanding.
