在刚升级到 Monterey 的 Mac 上，我在尝试cargo run一个简单的 Bevy 程序时得到以下信息。我已经重新安装了这里和其他地方推荐的 XCode CLT 。我试过弄乱一些cargo.yml，但没有成功。

error: could not compile `bevy_dylib` due to previous error

cargo.yml 是这样的：

[package]
name = "my_bevy_game"
version = "0.1.0"
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
bevy = { version = "0.5.0", features = ["dynamic"] }

我刚从这周开始遇到这个。我很确定这个确切的代码在几周前编译得很好。任何帮助将不胜感激。

main.rs 看起来像

use bevy::prelude::*;

struct Person;

struct Name(String);

fn add_people(mut commands: Commands) {
    commands.spawn().insert(Person).insert(Name("Elaina Proctor".to_string()));
    commands.spawn().insert(Person).insert(Name("Renzo Hume".to_string()));
    commands.spawn().insert(Person).insert(Name("Zayna Nieves".to_string()));
}

fn greet_people(query: Query<&Name, With<Person>>) {
    for name in query.iter() {
        println!("hello {}!", name.0);
    }
}

pub struct HelloPlugin;

impl Plugin for HelloPlugin {
    fn build(&self, app: &mut AppBuilder) {
        app.add_startup_system(add_people.system())
            .add_system(greet_people.system());
    }
}

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_plugin(HelloPlugin)
        .run();
}

更新：

绝对与我机器上的环境有关，因为在不同的 macbook 上它运行良好。

因此，如果您发现此问题并且代码可以在其他机器上运行，我找到了解决方案。使用标准脚本卸载 rustrustup self uninstall然后重新安装curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh，然后你应该会很好。
