Having the absolutely same issue, described here #36

[smartcontracts]

Confirmed. Gonna see what I can do. Also realized there's an issue with yarn clean because rm isn't recognized.

[smartcontracts]

Ok I have a fix. Will make a PR in just a sec.

Underlying problem turned out to be the one described here: https://essenceofcode.com/2019/11/20/linux-style-line-feeds-in-docker-desktop-on-windows/

In a nutshell, docker on windows expects files to have unix-style (LF) line endings but we had windows-style (CRLF) endings. There are various ways to fix this, but one of the simplest is to add a .gitattributes file with certain config values. See #974 for the fix. In the short term, while I wait for review on that PR, you can try this fix as follows.

First, checkout the branch, clear your cache, and reset. This forces the .gitattributes file to take effect:

cd optimism
git checkout kelvin/fix-windows
git rm --cached -r .
git reset --hard

Then the standard:

yarn clean
yarn build
cd ops
docker-compose down -v
docker-compose build
docker-compose up

I can confirm that it works now. Thanks @smartcontracts!
