strust stdweb无法编译

我想开始使用这个库，但由于某种原因，我的代码无法编译。代码如下：

#[macro_use]
extern crate stdweb;

fn main() {
    stdweb::initialize();

    let message = "Hello, 世界!";
    js! {
        alert( @{message} );
    }

    stdweb::event_loop();
}

下面是我在运行cargo web start时遇到的错误--target=wasm32 unknown：

我认为其他一些信息可能有用：

货物版本：

cargo 1.41.0-每晚（626f0f40e 2019-12-03）

~/.cargo/config的内部：

[target.arm-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc-7"

任何帮助都将不胜感激：）

编辑：我使用的是“基本操作系统”（基本上是ubuntu和更酷的ui）。试图建立在稳定的基础上会给我同样的错误

Edit2:

Edit3:

cargo web--版本

返回

cargo web 0.6.26

您的链接器或编译器设置未正确设置，或以某种方式更改

错误：未知参数：-fuse ld=gold

从

RUSTFLAGS

、

ld

环境变量或编译器选项中删除标志：

-fuse ld=gold

使用详细标志（

-v

或

-verbose

）查看详细输出：

cargo web build-v--target=wasm32未知

WebAssembly快速、安全、可移植，是开放式Web平台的一部分。
因此，WebAssembly是独立于平台的（您不需要将其编译为ARM，它是基于虚拟机的，因此您需要一台主机来运行WebAssembly，例如，在web浏览器JavaScript虚拟机中运行WebAssembly。还有）

因为它是便携式的：
您可以在任何机器上使用正在工作的编译器构建它，然后将

.wasm

文件复制到目标web服务器机器上

要从头开始创建web hello world示例，请执行以下操作：

rustup目标添加wasm32未知
# https://github.com/koute/stdweb
货物搜索货物网
#cargo web=“0.6.26”#客户端web的cargo子命令
#cargo安装cargo web--版本0.6.26
货物安装货物网
文件~/.cargo/bin/cargo-web
货运网-版本
#货网0.6.26
#创建新项目，例如“123stdweb rs js”
货运新123stdweb rs js
cd 123stdweb rs js
货物搜索网站

添加到Cargo.toml文件，在

[依赖项]

之后结束：

stdweb = "0.4.20"  # A standard library for the client-side Web

main.rs

文件：

use stdweb;
use stdweb::js;

fn main() {
    stdweb::initialize();
    let message = "Hello from stdweb.";
    let result = js! {
        alert( @{message} );
        return 2 + 2 * 2;
    };
    println!("2 + 2 * 2 = {:?}", result);
    stdweb::event_loop();
}

    <script src="stdweb-rs-js.js"></script>

构建并运行web服务器以服务于

target/wasm32 unknown/debug/stdweb rs js.js

：

stdweb = "0.4.20"  # A standard library for the client-side Web

#使用Rust的原生WebAssembly后端编译到WebAssembly：
cargo web start--目标=wasm32未知

打开您的web浏览器：

firefoxhttp://localhost:8000

完成了

---

您可以发布以下版本：

cargo web build --release --target=wasm32-unknown-unknown
mkdir static
cp target/wasm32-unknown-unknown/release/stdweb-rs-js.js ./static/
cp target/wasm32-unknown-unknown/release/stdweb-rs-js.wasm ./static/

现在，您可以使用您最喜欢的静态web服务器提供

stdweb rs js.js

和

stdweb rs js.wasm

文件，例如

python3-m http.server 8080

使用简单的

/static/index.html

文件：

use stdweb;
use stdweb::js;

fn main() {
    stdweb::initialize();
    let message = "Hello from stdweb.";
    let result = js! {
        alert( @{message} );
        return 2 + 2 * 2;
    };
    println!("2 + 2 * 2 = {:?}", result);
    stdweb::event_loop();
}

我希望这会有所帮助。

您在哪个平台上构建项目？您是否与编译器的夜间版本绑定？@E_net4我在linux上构建的Safedown投票者。确切地说，它的“基本操作系统”基本上就是ubuntu，具有更酷的用户界面，但在系统上一切都像ubuntu一样工作。你能解释一下“捆绑”是什么意思吗？您好，您真的需要使用该版本的Rust编译器吗？可能是您刚刚偶然发现了一个特定的夜间工具链，它与stdweb不兼容。另外，别忘了用这些细节编辑你的问题。谢谢你的回复！可悲的是，在完成所有步骤后，我仍然会遇到同样的错误：（而且我不认为这是我的错，因为我让它在windows上正常工作，但它确实存在。我认为这只是cargo web的失败。嘿，我尝试了一些事情，最后感谢你，我发现我可以通过使用“RUSTFLAGS='-C linker=rust lld'cargo web start--target=wasm32 unknown”“。是否有任何方法可以让它在默认情况下这样做？好的，我找到了！出于某种原因，我的RUSTFLAGS环境变量设置为“-C link args='-fuse ld=gold”“默认情况下，我不知道它为什么会这样做，但在/etc/environment中清除RUSTFLAGS后，一切都很好。谢谢您的帮助：）
