Error: Couldn't find ethers-v5 (yarn workspaces)

See original GitHub issue

I’m getting the following error on the latest version of typechain:

Error: Couldn't find ethers-v5. Tried loading: @typechain/ethers-v5, typechain-target-ethers-v5, /home/k/Projects/work/optimism/packages/contracts/ethers-v5.
Perhaps you forgot to install @typechain/ethers-v5?

This is happening within a yarn/lerna monorepo. It appears this is happening because the typechain package is being hoisted to the root level, but the @typechain/ethers-v5 package is not.

Turns out it was just luck indeed. The issue randomly reappeared later even after upgrading to 7.0.0. After much trial and error, the only thing which fixed it for me was:

"nohoist": [
  "**/typechain",
  "**/@typechain/*"
]

Just FYI, I’ve made target resolution more robust in the new version, so this should (no guarantees) be solved after the release.
