EEXIST: file already exists

See original GitHub issue

Behaviour

When I am deploying a directory I am getting this error:

EEXIST: file already exists, mkdir '/tmp/github-pages-3fqEIE/lib/absinthe/priv'

I am using mix (elixir’s build tool) to build a release. After running, mix will create a _build/prod directory with all the files needed to run the app.

Expected behaviour

Deploys as usual

Actual behaviour

Error: EEXIST: file already exists, mkdir '/tmp/github-pages-3fqEIE/lib/absinthe/priv'
