Can't do `diesel setup` with sqlite database?

$ diesel --version
diesel 0.11.0
$ sqlite3 --version

$ DATABASE_URL="sqlite:///tmp/database.sql" diesel setup
Creating database: sqlite:///tmp/database.sql
Unable to open the database file

I am having trouble doing anything through the diesel binary with a sqlite database. I feel like it must be something I'm doing wrong, but I haven't been able to figure it out. I've tried with sqlite:///tmp/database.sql and file:///tmp/database.sql with the same result. I've tried first opening the file with the sqlite3 binary and then trying diesel setup, to no avail. Can anyone tell me what I might be doing wrong here? Thanks!

Closing this because I just had to remove the "sqlite://" from the URL. Doing DATABASE_URL=/tmp/database.sql diesel setup seems to work fine.
