Build issues with nightly-2016-07-07

[freiguy1]

Hello there. I'm working on a REST api and am using several libraries like serde, diesel (orm), and iron. The latest nightly which diesel is able to compile with is nightly-2016-07-07. I'm attempting to get this project building and having errors when compiling quasi.

My Cargo.toml file looks like:

name = "league-api"
version = "0.0.1"

[dependencies]

# Serialization
serde = "0.8"
serde_json = "0.8"
serde_macros = "0.8"
syntex_syntax = "0.39"

# Iron
iron = "0.4"
persistent = "0.2"
router = "0.2"
bodyparser = "0.4"
hyper = "0.9"

# Data Persistence
diesel = "0.7"
r2d2-diesel = "0.7"
league_db = { path = "../db" }
r2d2 = "0.7"

# Util
regex = "0.1"
pwhash = "0.1"
rand = "0.3"
jwt = "0.4"
rust-crypto = "0.2"

My Cargo.lock is quite long, but if needed I can add it.

The error looks like:

error: aborting due to 2 previous errors
Build failed, waiting for other jobs to finish...
error: Could not compile `quasi`.

Any ideas?

Thanks!

Serde_macros and quasi_macros always support the newest nightly only. Nightly means you update every night.

The latest nightly which diesel is able to compile with is nightly-2016-07-07.

That means there is no nightly version that is supported by both the newest version of diesel and the newest version of serde, so you will need to use an old version of serde. See serde-rs/serde#470 for a way to do this.

Nightly means you update every night.

Too bad this isn't everyone's mentality. Thanks, I'll check it out.
