On Mac freshly upgraded to Monterey, I'm getting the following when attempting to cargo run a trivial Bevy program. I've reinstalled XCode CLTs like recommended here and other places. I've tried messing around with some of the cargo.yml with no success.

The cargo.yml is like this:
[package]
name = "my_bevy_game"
version = "0.1.0"
edition = "2018"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
bevy = { version = "0.5.0", features = ["dynamic"] }
I just ran into this starting this week. I am pretty sure this exact code was compiling fine a couple weeks ago. Any help would be greatly appreciated.
main.rs looks like
use bevy::prelude::*;
struct Person;
struct Name(String);
fn add_people(mut commands: Commands) {
commands.spawn().insert(Person).insert(Name("Elaina Proctor".to_string()));
commands.spawn().insert(Person).insert(Name("Renzo Hume".to_string()));
commands.spawn().insert(Person).insert(Name("Zayna Nieves".to_string()));
}
fn greet_people(query: Query<&Name, With<Person>>) {
for name in query.iter() {
println!("hello {}!", name.0);
}
}
pub struct HelloPlugin;
impl Plugin for HelloPlugin {
fn build(&self, app: &mut AppBuilder) {
app.add_startup_system(add_people.system())
.add_system(greet_people.system());
}
}
fn main() {
App::build()
.add_plugins(DefaultPlugins)
.add_plugin(HelloPlugin)
.run();
}
Update:
Definitely something about the environment on my machine because on a different macbook it worked fine.
So I found a solution if you discover this issue and the code works on other machines. Uninstall rust with rustup self uninstall and then renistall with the standard script curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh and then you should be good.
I'm having trouble with importing rand crate from crates.io. After adding the line rand="0.8.3" and then running command cargo build for the project, it keeps displaying the same errors:
error[E0432]: unresolved import `rand`
--> main.rs:1:5
|
1 | use rand::Rng;
| ^^^^ maybe a missing crate `rand`?
error[E0433]: failed to resolve: use of undeclared crate or module `rand`
--> main.rs:4:25
|
4 | let secret_number = rand::thread_rng().gen_range(1..=11);
| ^^^^ use of undeclared crate or module `rand`
error: aborting due to 2 previous errors
the cargo.toml file
[package]
name = "roller"
version = "0.1.0"
authors = ["User"]
edition = "2018"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
rand = "0.8.3"
Basically the simplest reproducible example is this single line of code:
use rand::Rng;
fn main(){
let secret_number = rand::thread_rng().gen_range(1..=11);
print!("{}",secret_number);
}
What's wrong with it?
Just in case:

In file Cargo.toml add lines:

And rebuild project!
It worked with these versions:
rustc 1.53.0
cargo 1.53.0
Took answer from here https://github.com/rust-lang/rust/issues/34616
got the same error when I run it with vs code(rust-analyzer).
When you press the run button
rustic main.rs this command is called in terminal, it will cause error.
Type this in terminal,
cargo build
cargo run
It works well
If you think that you did everything right and get a strange unable to import error like this then you could try cargo clean.
That will allow you to fully re-build your binary/library after that.
Hi I'm trying to explore Rust. What I'm trying to do is using glob module, when i build code with $cargo build and $cargo run it's succesfully builds and runs the executable but if i try it with $rustc main.rs it gives me
error[E0432]: unresolved import `glob`
--> src/main.rs:1:5

1 | use glob::glob;
| ^^^^ use of undeclared type or module `glob`
Any ideas?
Version : ╰─ rustc --version rustc 1.43.1 (8d69840ab 2020-05-04)
Code is here:
use glob::glob;
fn main() {
for entry in glob("/home/user/*.jpg").unwrap(){
match entry {
Ok(path) => println!("{:?}", path.display()),
Err(e) => println!("{:?}",e),
}
};
}

[dependencies]
glob = "0.3.0"
rustc on its own doesn't handle your dependencies, it just compiles stuff. When you run rustc on your file, it will start compiling it and encounter the unknown glob crate. Dependencies are handled by cargo via Cargo.toml.
Though you could only use rustc (see the answer here) it's a task that's considerably more difficult, that's why cargo is around.
I need to build the rustc compiler using a modified libc crate. I cloned the libc directory and made the changes, now how do I include the modified libc in my build?
This is my Cargo.toml

I'm writing a package derivation to install kryptco/kr and it fails on cargo build phase.
kryptco/kr has a submodule kryptco/sigchain which is written by rust.
In the Makefile of kryptco/sigchain, they use the cargo web deploy command to build its submodule. My package deriation fails on this cargo web deploy phase.
These two errors were given.
error: warning: replace for the non root package will be ignored, specify replace at the workspace root:

I don't think you'll get around the [replace] edit for the config files. The build failing at cargo web deploy is due to an outdated version of openssl-sys (which is discontinued). Here's how Parity fixed it. Looks like they edited the Cargo.lock file to depend on newer versions of this lib.
You need to make it a fixed-output path, for this take a look at nix-pills.
