`diesel` as a dependency does not compile when Postgres ist not installed

[kud1ing]

I want to use Diesel with Sqlite only:

cargo test
   Compiling pq-sys v0.3.2
error: failed to run custom build command for `pq-sys v0.3.2`
process didn't exit successfully: `/Users/lenny/Code/ts/target/debug/build/pq-sys-ac5f013e7abb629c/build-script-build` (exit code: 101)

When you say "diesel" do you mean diesel_cli? If so, you should install it with cargo install diesel_cli --no-default-features --features sqlite. If you're referring to the diesel crate itself, it doesn't rely on postgres unless you have features = ["postgres"] in your Cargo.toml.

Sorry, I accidentally copied the example with the Postgres feature enabled. :/

Sorry, I don't fully understand what you mean. Do you still need help, or did that comment resolve the issue for you?

[kud1ing]

No thanks, I am fine. The issue #735 regarding the CLI maybe could be mentioned in the guide, though.

Yes, we will be revamping the getting started guide so that it has a SQLite and MySQL specific page. I'll mention it once we do that.
