Lession5:TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')-Solved

[cccooler]

I'm learning 5-11 Ethers.js ，When I followed the code and running ,it drop the error.

async function main() {
  //HTTP://127.0.0.1:7545
  const provider = new ethers.providers.JsonRpcProvider(
    "HTTP://127.0.0.1:7545"
  );
  const wallet = new ethers.Wallet(
    "0xda09f9e05ec705b882178f422d22506c35b7b95bd588c1f9c5fc70ae97f0b867",
    provider
  );

I have solved the problem. Because the latest version of Ethers, ethers ^6.3.0, which appears to be unstable, you can easily solve the problem by downgrading to a previous version of Ethers, such as ethers 5.7.2.

To downgrade to ethers 5.7.2, run either of the following commands on your command line interface, depending on your package manager

For npm:

npm install ethers@5.7.2

For yarn:

yarn add ethers@5.7.2

Thanks cccooler, I found this issue as well. However, after downgrading to ethers 5.7.2 I still recieve the following error:

TypeError: ethers.wallet is not a constructor

Were you able to solve this as well?

Solved it with changing wallet to Wallet.
Adding the capital 'W':

const wallet = new ethers.Wallet`

It seems like you have solved the problem. Hope you a good day.
