error: failed to get 'actix-rt' as a dependency of package

[sm8082]

Hello, I'm getting error whilst building a new image using Dockerfile for a Rust program.

Code in my "main.rs" as below:
use actix_web::{web, App, HttpResponse, HttpServer, Result};
#[actix_rt::main]
async fn main() -> std::io::Result<()> {
HttpServer::new(||{
App::new()
.service(web::resource("/").route(web::get().to(index)))
})
.bind("0.0.0.0:4400")?
.run()
.await
}
async fn index() -> Result {
println!("Ch13 Docker Test");
Ok(HttpResponse::Ok()
.content_type("text/html; charset=utf-8")
.body(include_str!("../static/index.html")))
}

Cargo.toml dependencies:
[dependencies]
actix-web = "2.0.0"
actix-rt = "1.0.0"

Dockerfile code:
FROM rust:1-slim-buster AS base
ENV USER = root
WORKDIR /code
#RUN cargo init
COPY Cargo.toml /code/Cargo.toml
#RUN cargo fetch
COPY src/ src/
CMD ["cargo", "test", "--offline"]
FROM base AS builder
RUN cargo build --release
FROM rust:1-slim-buster
COPY --from=builder /code/target/release/Ch13_docker_test /usr/bin/Ch13_docker_test
EXPOSE 4400
ENTRYPOINT ["/usr/bin/Ch13_docker_test"]

---

When I run "sudo docker build -t ch13_docker1g .", I get the following error on my terminal in Linux:

Step 8/12 : RUN cargo build --release

if a proxy or similar is necessary net.git-fetch-with-cli may help here

It is causing too much pain and delays, if it could be resolved please. As per above it says network failure but this is not true because the net is clearly working fine.

Hm, I'm unfortunately unable to reproduce with that docker image.
Are you behind a proxy or have any other unusual network setup?
Does it continue if you set the net.git-fetch-with-cli config option to true?

Thanks for looking into this ehuss. I got it resolve by running the following commands, so it seems that my cargo required these updates:

cargo install cargo-vendor
cargo vendor
cargo install cargo-bdeps

I got wrong after run "cargo vendor"

Caused by:
  failed to load pkg lockfile

Caused by:
  failed to select a version for the requirement `rhai = "^1.8"`
  candidate versions found which didn't match: 1.7.0, 1.6.1, 1.6.0, ...
  location searched: crates.io index
  required by package `cargo-generate v0.16.0`
      ... which satisfies dependency `cargo-generate = "^0.16.0"` of package `webservice v0.1.0

anyone can help me ?

@Smilejohnson, what version of cargo are you using. This may be a case off #10623
