Fresh install with actix-web fails at compile on ring-asm

[devton]

Hello,

I'm facing this error when seting up a new project using newest actix-web.

specs:

Rust: 1.27.2

Cargo.toml:

[package]
name = "memeexample"
version = "0.1.0"
authors = []

[dependencies]
#cookie = "0.11"
actix-web = "0.7.3"
#maud = "0.18.1"
maud = { version = "0.18.1", features = ["actix-web"] }

error when cargo install

warning: To build the current package use `cargo build`, to install the current package run `cargo install --path .`

Thanks for reporting. Looks like we need to update our version of actix-web. Happy to take a PR to do this.
