Fix #734

[yufansong]

I think the problem in #734 is more like the user didn't launch docker locally. Not permission problem.

An alternative is to remove pnpm from our dependencies, which I would prefer: https://github.com/OpenDevin/OpenDevin/pull/823

Let's discuss! https://github.com/OpenDevin/OpenDevin/discussions/820

Looks like pnpm is gone, so we can close this 😄
