英文:
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#installation
gstreamer 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`
英文:
I'm trying to run gstreamer crate on macOS (latest version)
but getting use of undeclared crate or module gst
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"
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:
use gst::prelude::*;
^^^ use of undeclared crate or module `gst`

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::*;
