use of undeclared crate or module 'gst'
问题
我试图在 macOS（最新版本）上运行 [gstreamer crate][1]，但出现了 `use of undeclared crate or module gst` 的错误。Cargo.toml[package]name = "gstreamerDemo"version = "0.1.0"edition = "2021"[dependencies]gstreamer = "0.20.2"[target.'cfg(target_os = "macos")'.dependencies]cocoa = "0.24"objc = "0.2.7"[1]: https://crates.io/crates/gstreamer#installationgstreamer 是使用二进制安装的（而不是使用 homebrew 安装）。❯ pwd/Library/Frameworks/GStreamer.framework使用 `cargo add gstreamer` 添加了依赖项。代码：use gst::prelude::*;fn main() {gst::init().unwrap();}错误信息：use gst::prelude::*;^^^ 未声明的 crate 或模块 `gst`

but getting use of undeclared crate or module gst
Cargo.toml

gstreamer is installed using the binaries (and not homebrew)
❯ pwd/Library/Frameworks/GStreamer.framework
added dependencies using cargo add gstreamer
code:
use gst::prelude::*;fn main() {get::init().unwrap();}
error:

无法在你的 Cargo.toml 中导入名为 gstreamer 的依赖，并在你的源代码中将其命名为 gst。但你可以通过以下方式重命名它，要么直接添加它并执行以下操作：
cargo add gstreamer --rename gst
或者通过直接编辑 Cargo.toml 文件，删除 gstreamer = "0.20.2" 并将以下内容添加进去：
[dependencies]gst = { version = "0.20.2", package = "gstreamer" }
当然，你也可以使用该 crate 的实际名称：
use gstreamer::prelude::*;
英文:
You cannot import a dependency gstreamer in your Cargo.toml and use it as gst in your source code. You could however rename it, either by directly adding it with
cargo add gstreamer --rename gst
or by editing the Cargo.toml directly remove the gstreamer = "0.20.2" and add the following instead:
[dependencies]gst = { version = "0.20.2", package = "gstreamer" }
Of course instead of renaming you could also use the crates actual name:
use gstreamer::prelude::*;
