Error: Unsupported language version '0.8.27'.

majinbot commented 2 months ago

Hello, I will get the stack trace printed below if I try running any HH task with your plugin imported in HH config import "@openzeppelin/hardhat-upgrades".

We ruled any HH fault with @alcuadrado, whom just released support for latest solc: https://github.com/NomicFoundation/hardhat/issues/5723

Released in Hardhat v2.22.11.

bun run compile
$ hardhat compile

For me, this is mitigated by manually providing the latest @nomicfoundation/slang commit in package.json, deleting node_modules with package-lock.json, and doing npm i.

"overrides": {
    "@openzeppelin/upgrades-core": {
      "@nomicfoundation/slang": "git://github.com/NomicFoundation/slang.git#15c437c6c4902cd43e0027f750ba59e8f22f47f9"
    }
 }

Note that this is a temporary solution before the new @nomicfoundation/slang version release.

@majinbot im not able to replicate the error with the sample hardhat project and the configs you shared. slang released support for v0.8.27 (and also 0.8.28) so i think it should be working ok. can you let me know if the issue persists?
