"git add/rm <conflicted_files>", then run "git rebase --continue".
You can instead skip this commit: run "git rebase --skip".
To abort and get back to the state before "git rebase", run "git rebase --abort".

Also /Users/nikivi/go/src/github.com/ry/v8worker2/.git/modules/depot_tools/rebase-apply/ dir is empty for me.

As a heavy-handed solution, this should ensure you have all the files you need

git clone https://github.com/ry/v8worker2.git . \
    && rm -rf v8 \
    && git clone https://github.com/v8/v8.git 
    && rm -rf depot_tools \
    && git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git \
    && git submodule update --init --recursive
