When I try to install dependencies with Hardhat, the "Typechain" folder does not appear in the directory

After installing all the dependencies, I noticed that the "typechain" folder was missing in the typescript hardhat. How can I retrieve it?

Try running npm init

Then, do npm install --save-dev hardhat

Next, run npx hardaht

You should see an option to select an Advanced sample project....

For a complete set of dependencies, consider running npm install --save-dev "hardhat@^2.8.2", "@nomiclabs/hardhat-waffle@^2.0.0", "ethereum-waffle@^3.0.0", "chai@^4.2.0", "ethers@^5.0.0", "solhint@^3.3.6", "solidity-coverage@^0.7.16", "@typechain/ethers-v5@^7.0.1", "@typechain/hardhat@^2.3.0", "@typescript-eslint/eslint-plugin@^4.29.1", "@typescript-eslint/parser@^4"

Answer №2

After I mistakenly deleted the typechain folder, I encountered a similar issue.

Make sure to execute the following command before proceeding with npx hardhat compile:

npx hardhat clean or alternatively yarn hardhat clean in my case.

Referencing the official documentation:

Caution: Prior to initial use, ensure to run hardhat clean, otherwise TypeChain may not generate the necessary typings.
