I've built a simple app with these dependencies:
[dependencies]
core-foundation = { version = "0.9", features = ["with-chrono"] }
With cargo 1.62.1 (a748cf5a3 2022-06-08). My platform is a Macbook Air M1 (the target might matter, not sure).
And I'm getting this error:
error: cyclic package dependency: package `chrono v0.4.21` depends on itself. Cycle:
package `chrono v0.4.21`
... which satisfies dependency `chrono = "^0.4"` of package `core-foundation v0.9.3`
... which satisfies dependency `core-foundation = "^0.9"` of package `iana-time-zone v0.1.42`
... which satisfies dependency `iana-time-zone = "^0.1.41"` of package `chrono v0.4.21`
If I clone core-foundation and build it myself using cargo build --features="with-chrono", I'm not getting any error.
Any idea how to investigate this issue?
Unfortunately, there isn't much you can do if the cyclic dependency occurs with crates you don't control. You could attempt to "fix" one of the crates by cloning and modifying it to avoid a problematic dependency and override your dependencies with the fixed version.
Your best bet is to notify the maintainers of the crates involved. If the issue only arose recently, you can try locking your dependencies to an earlier version as a workaround.
This particular issue seems to be resolved already. It likely happened when chrono added iana-time-zone as a dependency in version 0.4.21. However, the fix was for iana-time-zone to change its dependency from core-foundation to core-foundation-sys in version 0.1.45 to break the cycle.

So this problem is just arising in one rust project of mine. Cargo is in the path and this problem arose when I added one new dependency to my project and now I am stuck with this.
I have tried looking for the answer on the internet and did not find success yet, I do not know what else to try next.
cargo metadata --manifest-path <path to the file>
Works in the console I do not know why is this not working right now.
I am running this on Manjaro and my text editor is Vim with YouCompleteMe being used for AutoComplete.
If someone can point out what is wrong with the dependencies, I would be very thankful.
Thanks.
phf 0.11 requires Rust 1.60. You need to either update your Rust compiler to at least that version, or follow the chain of dependencies and downgrade the postgres crate so that you don't require phf 0.11.
I have the crates oauth2 (v4.1.0) and sqlx[json] (v0.5.5):
[dependencies]
oauth2 = "4.1.0"
sqlx = { version = "0.5.5", features = ["json"] }
When attempting to build, I am getting the following error:
error: cyclic package dependency: package `ahash v0.7.4` depends on itself. Cycle:
package `ahash v0.7.4`
... which is depended on by `hashbrown v0.11.2`
... which is depended on by `indexmap v1.7.0`

... which is depended on by `js-sys v0.3.51`
... which is depended on by `getrandom v0.2.3`
... which is depended on by `ahash v0.7.4`
This only happens when I activate the json feature flag on sqlx. How do I troubleshoot this kind of problem? Are there any workarounds to make these libs/features work together? What are the alternatives?
After trying a few things back and forth, the only solution I found, was to update the lockfile to the latest version, using:
cargo update
After that, cargo clean && cargo build worked like a charm! Seems like some older patch versions seem to have conflicts, but the changes in the Cargo.lock were too big to track down, which crate combination it was. I hope that helps anybody else!
EDIT: After more communication and searching, I got referred to an issue directly at the ahash github project: https://github.com/tkaitchuck/aHash/issues/95.
According to that, the actual official "workaround" was / is, to pin the indexmap crate to:
indexmap = "=1.6.2"
However when looking into my Cargo.lock file, it seems to work with now:
indexmap = "1.7"
I'm following this tutorial here and have also looked into Rocket's official guide of setting up a web server.
I've set as default the nightly builds. But I get the following error:
error: failed to select a version for the requirement `ring = "^0.11.0"`
candidate versions found which didn't match: 0.16.11, 0.16.10, 0.16.9, ...
location searched: crates.io index
required by package `cookie v0.9.1`
... which is depended on by `rocket v0.3.6`
... which is depended on by `my-project`
Obviously there's some mismatch with the dependencies, but since ring is something required by the framework itself, I'm not sure how to debug this... furthermore, I'm using the latest versions of cargo and rust:
cargo 1.43.0-nightly (... 2020-02-18)
rustc 1.43.0-nightly (... 2020-02-21)
ring v0.11.0 was yanked from crates.io (see this issue for some background). Since some versions rocket depended on versions of ring that were yanked, those versions of rocket will no longer work.
Upgrading to rocket v0.4.0 (or the latest v0.4.2) should solve this issue.
I'm facing this problem when I try to cargo build:
error: native library openssl is being linked to by more than one version of the same package, but it can only be linked once; try updating or pinning your dependencies to ensure that this package only shows up once
openssl-sys v0.6.7
openssl-sys v0.7.13
Cargo and Rust versions:
$ cargo --version
cargo 0.11.0-nightly (3ff108a 2016-05-24)
$ rustc --version
rustc 1.11.0-nightly (7746a334d 2016-05-28)
Files:
Cargo.toml
Cargo.lock
can't get why this doesn't compile and how to solve this problem.
Thank you!
The way that linking works, you can only have a single version of a native library linked, otherwise you end up with duplicate symbols. Cargo's links manifest key helps prevent you from accidentally linking to the same set of symbols twice.
To solve it, you need to read through your Cargo.lock (it's not a difficult file format to understand). Find the crates that have the offending library as a dependency and note which ones have conflicting versions.
Then you have to manually resolve your dependencies so that their dependencies use the same version of the native library.
In this case, the important aspects of the dependency chain are:
server (0.0.1) => cookie (0.2.4) => openssl (0.7.13)
=> hyper (0.6.16) => cookie (0.1.21) => openssl (0.6.7)
To fix it, modify your Cargo.toml to use the same version of cookie as hyper. Then you will implicitly get the same version of openssl.
To be honest, this is one of the roughest parts of Rust at the moment. At least this version of the "multiple different versions of the same crate" strangeness provides a straight-forward Cargo error.
I want to use Yesod web framework with yesod-auth-oauth, but I encountered a dependency problem while cabal-dev install:
/Users/kenta/myapp/oryza% cabal-dev install
Resolving dependencies...
cabal: cannot configure yesod-platform-1.0.2. It requires data-default ==0.4.0
For the dependency on data-default ==0.4.0 there are these packages:
data-default-0.4.0. However none of them are available.
data-default-0.4.0 was excluded because authenticate-oauth-1.3.0 requires
data-default ==0.3.*
data-default-0.4.0 was excluded because data-default-0.3.0 was selected
instead
data-default-0.4.0 was excluded because oryza-0.0.0 requires data-default
==0.3.*
I don't have any idea of what's wrong.
What I did is just inserting one line in Cabal file:
yesod-auth-oauth >= 1.0 && < 1.1
The default scaffolding works fine, which is created through yesod init.
The version information
yesod-core: 1.0.1
cabal-dev: 0.9.1 (build with Cabal 1.14.0)
cabal-install: 0.10.2
GHC: 7.0.4
OS: Mac OS X Lion
Thanks.
This looks like an overly restrictive upper bound in the authenticate-oauth package. It would be best to follow up directly with the maintainer of that package.
In general, these kinds of issues are a side-effect of following the Package Versioning Policy. Basically, it's a trade-off between having these "refuse to compile" annoyances and more insidious "can't compile" problems.
I don't remember for sure, but I think my change to the cabal file for yesod-auth-oauth fixes this.
