为什么 Rust 找不到 "js_sys" 箱子？

Question

我是生锈新手。我正在尝试使用包含 Math::log 的板条箱 js_sys。正如板条箱网站告诉我的那样，我已经包含了 js_sys = 0.3.48，然后在 main.rs 中包含了 use js_sys::Math::log;。我得到一个错误，说 rust 找不到箱子。

复制步骤：

在Cargo.toml

[package]
name = "sim"
version = "0.1.0"
authors = ["Excluded for privacy"]
edition = "2018"

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

[dependencies]
js_sys = "0.3.48"
rand = "0.8.3"

在我的顶部 main.rs

// Luke Anglin and Tobi Solarin
use js_sys::Math::log;
use rand::prelude::*; // For the rng
const n: i32 = 1_000; // The number of trials

错误

error: no matching package named `js_sys` found
location searched: registry `https://github.com/rust-lang/crates.io-index`
perhaps you meant: js-sys
required by package `sim v0.1.0 (/Users/lukeanglin/Desktop/Probability/Project2/simulator/sim)`

Answer 1

在您的 Cargo.toml 中将 js_sys 更改为 js-sys，它应该可以工作。（如您发布但容易被忽视的错误中所述）
