Yarn add solc not adding package.json, node_modules, or yarn.lock files to directory

[hhirshland]

Hello!

I have been caught up on the section of the tutorial where I am supposed to add package.json, node_modules, and yarn.lock to my folder by running the command:
yarn add solc

I am getting this error:
warning package.json: No license field warning package-lock.json found. Your project contains lock files generated by tools other than Yarn. It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. To clear this warning, remove package-lock.json. warning No license field [1/4] 🔍 Resolving packages... [2/4] 🚚 Fetching packages... error hardhat@2.9.9: The engine "node" is incompatible with this module. Expected version "^12.0.0 || ^14.0.0 || ^16.0.0". Got "18.3.0" error Found incompatible module. info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.

I'm trying to figure out what is going on, and why this is happening. It looks like my node version is incompatible, but given it expects ^12, and I am on 18, I don't think that should be the issue? It also says I should remove package-lock.json, however I do not see that in my folder (and have tried removing it but get error that no file exists).

I saw a similar post where the person was able to solve issue by deleting node_modules in other directories. I tried that as well, but no luck.

Thanks!

Maybe you don't have yarn installed in your wsl or whatever terminal you are using. Check

yarn --version

If it gives you a version number then let us know here. if it gives back nothing or err then install yarn first using npm.....

And check this StackOverflow post as well

You have node version 18.3.0 Which is currently not compatible with hardhat, install LTS version of node. And delete any package-lock.json file in your folder.

Ahh ok, thank you! May be a dumb question, but how do I go about installing the LTS version and then setting that to the default version on my computer (instead of 18.3.0)?

Thanks for the help!

Ahh, think I was able to figure it out! I needed to uninstall the 18.3.0 using homebrew. The other issue was that I needed to run
yarn init in the directory first before
yarn add solc. This seems to have fixed my issue, I now have the files!

Hey, so I did all the steps you have mentioned here. I have yarn installed and have node version 16.14.2 , but when trying to install yarn add ethers , it seems it installs it but when I check the version using : ethers --version , it still says command not found.
I have deleted the file package-lock.json. Do I also need to delete package.json?
