zksolc compiler version (1.5.12) not within the allowed range

[eierina]

I'm using zksync-sso-clave-contracts (commit e5e624b) for some project, and at some point I started to get this error message during build:

> zksync-sso-contracts@ build /Users/dev/Projects/zksync-sso-clave-contracts
> pnpm hardhat compile

Error in plugin @matterlabs/hardhat-zksync-solc: The zksolc compiler version (1.5.12) in the hardhat config file is not within the allowed range. Please use versions 1.3.13 to 1.5.3.

Not sure what changed, I was able to build and deploy until I wasn't. This started few days ago, no changes to the project.

Getting the same error also when using main latest.

I'd appreciate some help with this.

Hey, I wasn't able to reproduce:

❯ git checkout e5e624b
❯ pnpm build

> zksync-sso-contracts@ build zksync-sso-clave-contracts
> pnpm hardhat compile

Make sure there are actually no changes in your code, perhaps try to also reinstall the dependencies (rm -rf node_modules && pnpm i) and clear the hardhat cache (pnpm run clean)

Yeah, today is working fine   🤷‍♂️

pnpm build

pnpm hardhat compile
