由于“ar crs”“格式错误的对象（未知加载命令1）”，无法在macOS Mojave上编译Actix

Question

我无法使用Actix编译基本示例。我怀疑我可能会遗漏一些图书馆，但我不知道它可能是什么。我几天前也升级到Mojave，但我不确定这是否相关。

它似乎抱怨ar crs和运行此命令时ranlib发生的内部错误。

卖弄.人生:

extern crate actix_web;
use actix_web::{server, App, HttpRequest};

fn index(_req: &HttpRequest) -> &'static str {
    "Hello world!"
}

fn main() {
    server::new(|| App::new().resource("/", |r| r.f(index)))
        .bind("127.0.0.1:8088")
        .unwrap()
        .run();
}

Cargo.toml：

actix-web = "0.7.8"

Backtrace我获得：

complete backtrace太大而无法包含在Stack Overflow上。

Answer 1

它通过MacPorts安装cctool后似乎有效。

出于某种原因，通过brew安装它似乎不起作用。

Answer 2

我有同样的错误。

当我从这个水龙头用921替换cctools 855然后cargo build工作：https://github.com/dgsga/homebrew-cctools

brew unlink cctools
brew tap dgsga/cctools
brew install dgsga/cctools/mtoc

Mojave 10.14.3，Rust 1.33.0，actix-web 0.7.18
