Failed cargo build

[izzyyau]

I ran "cargo build", but it gives me error:

error: failed to select a version for the requirement `libgit2-sys = "^0.14.0"`
candidate versions found which didn't match: 0.13.2+1.4.2, 0.13.1+1.4.2, 0.13.0+1.4.1, ...
location searched: crates.io index
required by package `git2 v0.15.0`
    ... which satisfies dependency `git2 = "=0.15.0"` (locked to 0.15.0) of package `cargo-registry-index v0.0.0 (/home/yiggu3/crates.io/cargo-registry-index)`
    ... which satisfies path dependency `cargo-registry-index` (locked to 0.0.0) of package `cargo-registry v0.2.2 (/home/yiggu3/crates.io)`

Is anybody have any idea to fix it?

What project were you trying to build? What dependencies did it have?
What is in your lock file? Does it work if you delete your lock file?
What do you have configured in your .cargo/config files?

Hi, Thanks for your reply.
I just git clone the crates.io project, https://github.com/rust-lang/crates.io.git, on master branch, and try to build it.

At the first time, I followed the instruction listed in docs/CONTRIBUTING.md, install the required backend and frontend packages and when I cargo run it, it said "error: could not compile cargo-registry due to 348 previous errors; 21 warnings emitted"

On the second time, I tried not to install anything at first, just install rust and clang, it gives me the error like I just I posted.

I didn't change anything just git clone it.

What versions of rustc and cargo do you have? (plesae paste the output of rustc -vV and cargo -vV) How did you install Rust?

[Turbo87]

this is most likely caused by rust-lang/cargo#10623, which indicates that your Rust/cargo versions are not up-to-date. running rustup update should fix that.

update: cargo run now runs fine. Unfortunately, I have no idea what fixed it, if you're facing the same issue, try getting a fresh copy of the repo
