Rust Image crc32fast - rust

I am very new to Rust. I have an issue with installing image crate:
[dependencies]
image = "0.23.14"
cargo 1.57.0 (b2e52d7ca 2021-10-21)
rustc 1.57.0 (f1edd0429 2021-11-29)
Microsoft Windows 10 Home
OS Version: 10.0.19043 N/A Build 19043
I get following compiling error:
error: failed to run custom build command for crc32fast v1.3.0
Probably some dependency is missing.

As it turned out, the problem was due to Kaspersky Anti Virus deleting the .exe file in build/crc32fast folder.
After adjusting Kaspersky I was able to compile.

cargo version 2021 required on Solana anchor build

I am trying to run anchor build and am receiving the following response:

It looks like your solana install is quite out of date.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

Cargo: "No such file or directory" error when compiling a Rust project

I'm trying to build a Rust project with cargo (on Ubuntu 20.04), and it seems I'm running into an error when compiling some of the dependencies.
I run cargo build --release, all of the external crates are downloaded, then it begins compiling some of them, but eventually runs into the error below:
> cargo build --release
Updating crates.io index
Downloaded ansi_term v0.12.1
Downloaded phf_generator v0.7.24
Downloaded cmake v0.1.48

...
And I get the exact same error for 15 other packages. It's obvious why the path wouldn't exist, but I'm not sure where to begin fixing this issue.
I've tried uninstalling and reinstalling Rust, but I'm new to the language and not sure what to do beyond that, so help is much appreciated. Thanks!
I linked it above, but the project in question is https://github.com/iden3/circom.

Build fails with Error: Pear requires a 'dev' or 'nightly' version of rustc even after a successful rustup override set nightly

I had a similar issue while using rocket. Same error message too, Error: Pear requires a 'dev' or 'nightly' version of rustc.
If you get to the get-started page on rocket framework website. It says, "Rocket makes abundant use of Rust's syntax extensions and other advanced, unstable features. Because of this, we'll need to use a nightly version of Rust."
My issue was I was not using a nightly version of rust. Running this on my terminal in my project directory did it for me.
rustup override set nightly
If you check the cargo version for that directory after,
cargo version
you will confirm it has switched to nightly version
Failed compilation even with nightly
It looks like you have some outdated dependencies (pear-codegen probably being the one that causes trouble), updating these may resolve the compilation issues.
General notes on how to override the toolchain
Using rustups override works fine, but it is bound to your local rustup configuration and not specified inside the project.
In order to achieve this, thereby making the project more portable and allowing others to always use the correct toolchain, I would recommend the toolchain file. It can look something like this (example taken from linked page) and will accurately specify the required toolchain only for the containing project.
# rust-toolchain.toml
[toolchain]
channel = "nightly-2020-07-10"
components = [ "rustfmt", "rustc-dev" ]
targets = [ "wasm32-unknown-unknown", "thumbv2-none-eabi" ]
profile = "minimal"
For your purposes a simple configuration like this will most likely be all you need, although adding the components you want to use would be beneficial.
[toolchain]
channel = "nightly"
My issue was with rust-analyser that wouldn't start because multiple rocket dependencies needed nightly or dev version of rustc.
These steps fixed my issue:
Switch to nightly for my rocket project by running rustup override set nightly inside the app folder.
Remove all target folders in my project. (I also had one in root)
Manually remove the faulty cached packages from cargo cache. cd ~/.cargo/registry/cache/github.com-xxxxxxxxxxxx && rm -r pear_codegen-0.1.5/

Unable to build bevy on windows rust

I am trying to use bevy game engine with rust on windows. I have x86_64-mingw installed on my machine.
I have setup the rust tool chain default to x86_64-pc-windows-gnu. I put bevy = "0.4.0" under my dependencies in the Cargo.toml.
I tried cargo build and I get the following error
error: failed to run custom build command for `syn v1.0.63`
Caused by:

Edit:
My Antivirus was preventing it, and denying it access, so just turning my AV for sometime worked!
I've tried compiling a project that uses bevy = "0.4.0" and was able to build with the stable-x86_64-pc-windows-msvc toolchain but not with stable-x86_64-pc-windows-gnu.
In my case, bevy-glsl-to-spirv is the crate that failed to build. On the bevy book is specified that you must have VS build tools 2019 installed. They do not explicitly say that you must use the msvc toolchain but as they require you to install VS build tools 2019 I guess you must compile the code using stable-x86_64-pc-windows-msvc.
You can download VS build tools 2019 here.
Also make sure that you install the stable-x86_64-pc-windows-msvc toolchain:
rustup toolchain install stable-x86_64-pc-windows-msvc
Set this toolchain as the default toolchain.
rustup default stable-x86_64-pc-windows-msvc
Finally, make sure the toolchain has been installed and set as the default toolchain:
rustup toolchain list
You should see:
stable-x86_64-pc-windows-gnu
stable-x86_64-pc-windows-msvc (default)
Try to cargo build and it should work like a charm.

Rust compiler can't find crate for 'std'

I recently downloaded and unpacked the Rust Language from this site (Linux 64-bit).
I then installed Rust using the given script in the download install.sh:
root#kali:~# /root/rust-1.9.0-x86_64-unknown-linux-gnu/install.sh
install: uninstalling component 'rustc'
install: creating uninstall script at /usr/local/lib/rustlib/uninstall.sh
install: installing component 'rustc'
install: installing component 'rust-std-x86_64-unknown-linux-gnu'
install: installing component 'rust-docs'
install: installing component 'cargo'
Rust is ready to roll.
I am trying to install a crate with cargo, but I keep running into this error:
root#kali:~# cargo install racer
Updating registry `https://github.com/rust-lang/crates.io-index`
Compiling winapi v0.2.7
Compiling bitflags v0.5.0

error: can't find crate for `std` [E0463]
error: aborting due to previous error
error: failed to compile `racer v1.2.10`, intermediate artifacts can be found at `/root/target-install`
cargo install cargo-edit failed with the same result as above, so it's not limited to one particular package.
Even putting a simple program:
fn main() {
println!("Hello, world!");
}
in a file named hello.rs and running rustc hello.rs does not compile; it gives the same error: error: can't find crate for 'std' [E0463].
The download came with a directory named rust-std-x86_64-unknown-linux-gnu, which I assume is the std crate. How do I instruct rustc to find this directory when trying to locate the std crate?
The following will work for the simplest of compilations.
Assuming you extracted the tar file to, say
$HOME/rust-1.10.0-x86_64-unknown-linux-gnu
Then run
arch=x86_64-unknown-linux-gnu
dl=$HOME/rust-1.10.0-$arch
$dl/rustc/bin/rustc -L $dl/rustc/lib \
-L $dl/rust-std-$arch/lib/rustlib/$arch/lib \
hello.rs
But I'm sure a better way would be to run rustup as Chris Morgan suggest.
Coupla more points
You shouldn't compile code as root.
You may have to relogin or run bash -l to get the environment setup by rustup.
(Fellow rust newb here)
For me (Arch Linux) removing system's Rust fixed the issue.
pacman -Rc rust
I think there was a conflict among user installed Rust and system installed one.
