Resolve errors from hardhat-ethers

[rootulp]

I apologize if this is unique to my developer environment but... I could previously run yarn install in this package but now I'm encountering:

$ for f in typechain/*.d.ts; do mv -- "$f" "${f%.d.ts}.ts"; done
$ tsc -p tsconfig.dist.json
typechain/commons.ts:20:5 - error TS1256: A rest element must be last in a tuple type.

20     ...EventArgsArray,
       ~~~~~~~~~~~~~~~~~

typechain/hardhat.ts:7:3 - error TS2305: Module '"../node_modules/@nomiclabs/hardhat-ethers/dist/src"' has no exported member 'FactoryOptions'.

7   FactoryOptions,
    ~~~~~~~~~~~~~~

typechain/hardhat.ts:8:3 - error TS2305: Module '"../node_modules/@nomiclabs/hardhat-ethers/dist/src"' has no exported member 'HardhatEthersHelpers'.

8   HardhatEthersHelpers as HardhatEthersHelpersBase,
    ~~~~~~~~~~~~~~~~~~~~


Found 3 errors.

I've rm -rf node_modules and retried with no luck. Any ideas?
