我正在按照本教程使用cairo-rs为图像绘制一些东西。当我运行我的代码时，我收到一个非常冗长的错误。重要的部分似乎是：
linking with "cc" failed: exit code: 1
和
ld: library not found for -lgobject-2.0
clang: error: linker command failed with exit code 1
我通过MacPorts安装了Cairo，所以这应该不是问题。我从教程中复制了 Cargo.toml 文件，除了最新的软件包：
[dependencies]
png = "0.12.0"
cairo-rs = {version = "0.4.1", features = ["png"]}
我也尝试了教程中列出的版本，但遇到了同样的错误。
Rust 问题 18610 似乎也有类似的错误，建议安装libc-dev.我不知道那是什么，也不知道为什么它会解决任何问题。
我在某处看到这可能是命名冲突，所以我更改了项目的名称以免冲突，但这没有帮助。
详
- 我在稳定的 Rust 上，我什至重新安装了它。
- MacOS High Sierra，版本10.13.3(17D47(
完全错误
error: linking with `cc` failed: exit code: 1

您需要安装正确的glib和cairo开发库。
如果您的操作系统与 Debian 相关，请键入apt install libglib2.0-dev。
如果您使用的是macOS和自制软件，请键入brew install glib然后键入brew install cairo。
