rust - 为什么 Rust 找不到“js_sys”板条箱？

Question

我是生锈的新手。我正在尝试使用js_sys包含Math::log. 我已经js_sys = 0.3.48按照 crate 网站告诉我的内容包含在内，然后use js_sys::Math::log;在main.rs. 我收到一个错误，说 rust 找不到板条箱。

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)`

在 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）
