我想开始使用stdweb库，但是由于某些原因，我的代码无法编译。这是代码：
#[macro_use]
extern crate stdweb;
fn main() {
stdweb::initialize();
let message = "Hello, 世界!";
js! {
alert( @{message} );
}
stdweb::event_loop();
}
这是我运行cargo web start --target=wasm32-unknown-unknown时遇到的错误：
error: linking with `rust-lld` failed: exit code: 1

一些我认为可能有用的附加信息：
货物版本：cargo 1.41.0-nightly (626f0f40e 2019-12-03)〜/ .cargo / config的内部：
[target.arm-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc-7"
任何帮助将不胜感激：）
编辑：我正在使用“ elementary os”（基本上是带有较酷ui的ubuntu）。尝试在稳定版本上构建会给我完全相同的错误。
WebAssembly是快速，安全，便携式，并且是开放Web平台的一部分。因此，WebAssembly是与平台无关。注释掉（删除）~/.cargo/config文件中的这些链接器行：
[target.arm-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc-7"
从头开始创建Web hello世界示例：
rustup target add wasm32-unknown-unknown
# https://github.com/koute/stdweb
cargo search cargo-web
# cargo-web = "0.6.26" # A Cargo subcommand for the client-side Web
# cargo install cargo-web --version 0.6.26
cargo install cargo-web
file ~/.cargo/bin/cargo-web
cargo-web --version
# cargo-web 0.6.26
# create new project e.g. "123stdweb-rs-js"
cargo new 123stdweb-rs-js
cd 123stdweb-rs-js
cargo search stdweb
# Add to Cargo.toml file end after [dependencies]:
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();
}
构建并运行Web服务器以服务target/wasm32-unknown-unknown/debug/stdweb-rs-js.js：
# Compile to WebAssembly using Rust's native WebAssembly backend:
cargo web start --target=wasm32-unknown-unknown
