Solana/Anchor error: (yanked dependencies) Failed to obtain package metadata: `cargo metadata` exited with an error: Updating crates.io index

I just set up a new anchor project yesterday, every command runs smoothly.

Today I installed a new anchor project. I run anchor test to see if the project is set up correctly. I am getting this error:

Failed to obtain package metadata: `cargo metadata` exited with an error:     Updating crates.io index
error: failed to select a version for the requirement `anchor-lang = "^0.23.0"`
candidate versions found which didn't match: 0.24.2
location searched: crates.io index
required by package `myAnchorProject v0.1.0 (.../programs/myAnchorProject)`

It is not clear what candidate versions mean. I deleted node_modules and install it with "@project-serum/anchor": "^0.24.2", still same error.

I clear the lib.rs and testing file to see something different, but it still gives the same error.

executing cargo update is giving same error

It's not the problem with dependency in your package.json is due to the use of yanked rust crate anchor-lang

all the other version the 0.24.2 have been yanked so you can't build any cargo project which has yanked dependeny.

refer here https://crates.io/crates/anchor-lang/versions

what you need to do get it working is
go to <your-project-root>/programs/myAnchorProject/cargo.toml.
I'm assuming your program name is myAnchorProject or replace it with your program name.

your current cargo.toml must look something like

...
<other content goes here>
...

[dependencies]
anchor-lang = "^0.23.0"

you need to upgrade the anchor-lang version to 0.24.2 or any other version if available which is not yanked.

so your final cargo.toml should look like

...
<other content goes here>
...

[dependencies]
anchor-lang = "^0.24.2"
