Ethers error while trying to load the sdk

[Phenzic]

My code

import { BalancerSDK } from '@balancer-labs/sdk'

const balancer = new BalancerSDK({
  network: 5, // Mainnet
  rpcUrl: `https://eth-goerli.g.alchemy.com/v2/${process.env.ALCHEMY_API}`,
})

const { swaps } = balancer // Swaps module is abstracting SOR    

// console.log(swaps)
// // const balancer = new BalancerSDK(config);

const balance = new BalancerSDK(balancer);
const pool = await balance.pools.find(poolId);

    const main = async () => {
    const spotPrice = await pool.calcSpotPrice(
        ADDRESSES[network].DAI.address,
        ADDRESSES[network].BAL.address
        );
    console.log(spotPrice);
}

After following the procedure on the docs I keep getting the error

node:internal/modules/cjs/loader:1144
  const err = new Error(message);
              ^

Error: Cannot find module 'ethers'

Same issue here.

Same issue here.

Have you installed ethers?
We have an ethersV5 dependency. #560 has some more detail that might be useful - we'll hopefully push an update to fix that next week.

[youfoundron]

Yes. We ended up circumventing by using sor lib directly.

Should be fixed in version v1.1.6-beta.18
