Getting started cargo.toml not valid

[viraptor]

The getting started guide contains:

diesel_codegen = { version = "0.7.0", default-features = false, features = ["nightly", "postgres"] }

However cargo says:

error: Package `diesel_codegen v0.7.0` does not have these features: `nightly`

Using rustc 1.12.0-nightly (28ce3e8a5 2016-08-01)

I am having the same issue:

# rustup show
Default host: x86_64-unknown-linux-gnu

installed toolchains
--------------------

stable-x86_64-unknown-linux-gnu
nightly-x86_64-unknown-linux-gnu (default)

active toolchain
----------------

nightly-x86_64-unknown-linux-gnu (default)
rustc 1.12.0-nightly (8787a1233 2016-08-11)

I just did a literal copy-paste of the tutorial (including version = "0.7.0" and got this rather confusing error:

 diesel_demo git:(master) cargo run --bin show_posts
    Updating registry `https://github.com/rust-lang/crates.io-index`
error: Package `diesel_codegen v0.7.1` does not have these features: `nightly`

So it seems to be using v0.7.1 instead of 0.7.0.

Fix

• Take "nightly" out of diesel_codegen and set version to "0.7.1"
• set dotenv_macros version to "0.9.0"

Then it seems to compile and run

I would recommend just changing the "getting started" guide to using the newer versions. Not sure why Cargo is trying to get 0.7.1 when I am explicitly telling it to use 0.7.0 -- could be a Cargo bug?

The broken code is at (static link to commit):

re-reading the tutorial I see that you require a specific nightly version. I will just use that -- thanks!

FYI:

Not sure why Cargo is trying to get 0.7.1 when I am explicitly telling it to use 0.7.0 -- could be a Cargo bug?

Cargo treats 0.7.0 as ^0.7.0, which is the version range ≥0.7.0 AND < 0.8.0.
