Polyfills required after start, Can't resolve 'fs', 'crypto' and 'os' when starting the project

[RitzyDevUK]

I've just installed the interface project i've run the following:

1. yarn
2. yarn postinstall
3. yarn graphql
4. yarn contracts
5. yarn ajv
6. yarn i18n

When I got to yarn start, I'm receiving the following errors:

ERROR in ./node_modules/@lingui/message-utils/dist/generateMessageId.mjs 1:0-28 Module not found: Error: Can't resolve 'crypto' in 'C:\uniswap\interface\node_modules@lingui\message-utils\dist'

Module not found: Error: Can't resolve 'os' in 'C:\uniswap\interface\node_modules\cosmiconfig\dist'

Module not found: Error: Can't resolve 'fs' in 'C:\uniswap\interface\node_modules\cosmiconfig\dist'

Module not found: Error: Can't resolve 'module' in 'C:\uniswap\interface\node_modules\import-fresh\node_modules\resolve-from'

Note no modifications have been made to the projects. I'm running Node: v18.17.1 on windows.

I would assume the project should just work out of the box no? Any insight on how to fix this?

do you have node.js installed? are you on the version specified in .nvmrc?

Yeah I have Node LTS installed 18. The project works fine when using a linux distro, but from windows it gets Polyfill errors

following your answer, I installed WSL with ubuntu on my windows machine. install everything under ubuntu (Node, NVM, NPM, Yarn, Git, Java, type/Chrome, IPFS). the previous problem is now fixed but I have a new one and I'm not able to fix it (after 4 to 5 hours trying). Do you have any idea? the error is:

Failed to compile.

I don't use that version, but you should add a key for that in the .env
