本机库`glib`由多个包链接，并且只能通过一个包

Question

假设这段代码：

extern crate glib;

fn main() { 

当我cargo run时，我收到此错误：

error[E0463]: can't find crate for `glib`
  --> src/main.rs:17:1
   |
17 | extern crate glib;
   | ^^^^^^^^^^^^^^^^^^ can't find crate

我的Cargo.toml看起来像

[dependencies]
gtk = { git = "https://github.com/gtk-rs/gtk" }

[features]
default = ["gtk/v3_10"]

glib没有出现。如果我添加它：

[dependencies]
gtk = { git = "https://github.com/gtk-rs/gtk" }
glib = "0.1.3"

[features]
default = ["gtk/v3_10"]

我收到此错误：

error: native library `glib` is being linked to by more than one package, and can only be linked to by one package

如何修复此错误？它是什么意思以及为什么要显示它？

我看过 Cargo.lock ，似乎有name =" glib "，但我不知道如何处理这种情况：

我不知道你是否提到了我的评论，因为我现在已经收到了charge.toml，而且这是有效的，所以我把它留在这里：

Cargo.toml 这似乎解决了这个问题，但我不知道这是不是正确的方法
