Lesson 11 yarn.lock

[JR-Vickers]

I have not had any issues using yarn or hardhat so far, but when I tried to use them for Lesson 11 I get this error message:

I've googled the problem and it sounds like there might be an issue with the yarn.lock file, but I don't know what. I cloned it from the github repo and haven't modified it in any way.

My code can be found here.

@JR-Vickers Delete the package-lock.json file and run yarn install again.

I deleted package-lock.json and it still doesn't work.

[alymurtazamemon]

@JR-Vickers delete yarn.lock file and node_modules folder as well and rerun the install command, but make sure to either run yarn or npm, not both.

That fixed it, thanks!
