An unexpected error occurred when run yarn compile

[hadv]

An unexpected error occurred when run yarn compile as below output log due to hardhat compile the task before compile the smart contract?

An unexpected error occurred:

tasks/deployers/greeter.ts:4:43 - error TS2307: Cannot find module '../../typechain' or its corresponding type declarations.

4 import { Greeter, Greeter__factory } from "../../typechain";

Yeah this is a known issue, it's a catch-22 caused by the fact that one of the Hardhat tasks imports the TypeChain bindings which are not generated yet. See dethcrypto/TypeChain#371.

It can be fixed by adding TS_NODE_TRANSPILE_ONLY=true before running the command, but that'd be a chore. That's why I added this flag in the typechain script in package.json; I should create a compile script and add the flag in there too.

Yeah, this way might be better
