Checklist

• I have already looked over the issue tracker for similar issues.

Thank you for the issue. Installing from git is not expected to work, as cargo does not provide the tools we would need to make it work. You can install the latest master version by cloning the repo locally, and running cargo install from the diesel_cli directory there.

I can cargo build from that directory but cargo install --path . still fails with the same error.

I am able to confirm this issue.

It looks like the inability to install a local clone was due to a recent change in behavior w/ Cargo when installing a package in a workspace. I could not install on nightly (ac3c2288f 2018-04-18), but I could install on nightly (56733bc9f 2018-02-01). I would open an issue on https://github.com/rust-lang/cargo for that. In the mean time, applying this patch locally should help:

I'm heading out for the rest of the day. I do not think this is a bug in Diesel. If you have more issues, others can help you at https://gitter.im/diesel-rs/diesel
