我正尝试在macOS上运行gstreamer crate（最新版本）
但是得到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是使用二进制文件安装的（而不是自制的）

❯ pwd
/Library/Frameworks/GStreamer.framework

使用cargo add gstreamer添加了依赖项
代码：

use gst::prelude::*;

fn main() {
  get::init().unwrap();
}

错误：

use gst::prelude::*;
^^^ use of undeclared crate or module `gst`
