Rust .toml file was full of red line when we add new dependency
This is caused by the crash of internal package (say cargo)
we can solve this by following the steps
Please clear the cargo registry
rm -rf /home/username/.cargo/registry/
And follow the proceedure shown after this, if you use old version
For the reference, I've given the proceedure also below:
If you are trying to migrate from the previous edition (2018), the
process requires following these steps:
1. Start with `edition = "2018"` in `Cargo.toml`
2. Run `cargo fix --edition`
3. Modify `Cargo.toml` to set `edition = "2021"`
4. Run `cargo build` or `cargo test` to verify the fixes worked
More details may be found at
https://doc.rust-lang.org/edition-guide/editions/transitioning-an-existing-project-to-a-new-edition.html
You may need to to add --allow-no-vcs sometimes (it'll be prompted by the terminal) as below
cargo fix --edition --allow-no-vcs

I want to add the cargo dependencies rocket-okapi as git url, now I added the dependencies like in Cargo.toml this:
rocket-okapi = { git = "https://github.com/GREsau/okapi/tree/master/rocket-okapi"}
but when I build the project using cargo build command ,shows error like this:
$ cargo build

how to add the sub folder as dependencies in rust cargo? is it possible?
There are a few things here that need a bit of clarification.
When you add a Git dependency to Cargo.toml, it expects a repository. The URL you put in there is a directory in the repository, so cargo freaks out.
Secondly, when a Git dependency is specified, cargo first looks in the repository root for a Cargo.toml file. If it cannot find any, it will search for any Cargo.toml files where the package name is the same as the dependency.
The dependency you specified, rocket-okapi, doesn't exist in the repository, so cargo gives up. Changing the name of the dependency to 'rocket_okapi' fixes this.
TL;DR: Use this
rocket_okapi = { git = "https://github.com/GREsau/okapi" }

consider adding `cargo-features = ["edition2021"]` to the manifest

It looks like your solana install is quite out of date. I would install either 1.8.11 or just run solana-install update
At times, also consider downloading to like in my case I had to change from 2021 in my Cargo.toml file to 2018 and this has worked
I have been following these instructions:

I'm trying to cargo install a project with many dependencies. One of the later dependencies fails to build due to some system configuration issue:
cargo install diesel_cli
... many dependencies here...
Compiling diesel_cli v1.4.1
error: linking with `cc` failed: exit code: 1
|
= note: ...large output removed...
= note: ld: library not found for -lmysqlclient
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Once I think I've solved the system configuration issue, I need to re-run cargo install, wait a while for the first set of dependencies to build, then see if I get past the failure.
How can I avoid rebuilding all of those dependencies?
The error message contains the directory containing the failed build artifacts:
error: failed to compile `diesel_cli v1.4.1`, intermediate artifacts can be found at `/var/folders/_b/d4_bd15x7s5g99cjvyhpw26w0000gp/T/cargo-installDQOdPD`
You can pass that directory via the --target-dir option (or setting the CARGO_TARGET_DIR environment variable) to use it again, avoiding rebuilding the dependencies:
cargo install diesel_cli --target-dir=/var/folders/_b/d4_bd15x7s5g99cjvyhpw26w0000gp/T/cargo-installDQOdPD
I have an error when I execute cargo run. I added the line byteorder = "0.3.13" to my Cargo.toml, and here is the output of cargo run --verbose:

When I remove the line, everything is ok. How do I fix this error?
Fixed ! I just reinstalled rust nightly with multirust :)
