avm install latest fails

Question

Using Windows 11, I get this error when trying to use avm install latest

error[E0282]: type annotations needed for `Box<_>`
  --> C:\Users\username\.cargo\registry\src\index.crates.io-6f17d22bba15001f\time-0.3.29\src\format_description\parse\mod.rs:83:9

   |         ^^^^^
...
86 |     Ok(items.into())
   |              ---- type must be known at this point
   |
help: consider giving `items` an explicit type, where the placeholders `_` are specified
   |
83 |     let items: Box<_> = format_items

error: could not compile `time` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
error: failed to compile `anchor-cli v0.30.1 (https://github.com/coral-xyz/anchor?tag=v0.30.1#e6d7dafe)`, intermediate artifacts can be found at `C:\Users\username\AppData\Local\Temp\cargo-install121ovv`.                        
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.
Error: Failed to install 0.30.1, is it a valid version?

I'm not really sure how to go about fixing this. Any help would be really appreciated!

Answer 1

There is some problems with anchor AVM at the moment i think. Try installing it directly:

cargo install --git https://github.com/coral-xyz/anchor --tag v0.30.1 anchor-cli

Answer 2

Hi you can refer to this github comment. I was setting up avm recently into my new system. After searching a lot i found this comment, which solved the issue.

Answer 3

Windows support isn't all that great with Solana tooling, so first I'd suggest using WSL if you aren't already.

Answer 4

Go to the directory where the error is coming from

"C:\Users\username.cargo\registry\src\index.crates.io-6f17d22bba15001f\time-0.3.29\src\format_description\parse\mod.rs:83:9"

Edit the parse_owned function on line 75-88 in the mod.rs file with this:

    pub fn parse_owned<const VERSION: usize>(
    s: &str,
) -> Result<crate::format_description::OwnedFormatItem, crate::error::InvalidFormatDescription> {
    validate_version!(VERSION);
    let mut lexed = lexer::lex::<VERSION>(s.as_bytes());
    let ast = ast::parse::<_, VERSION>(&mut lexed);
    let format_items = format_item::parse(ast);
    let items: Box<[format_item::Item<'_>]> = format_items
        .map(|res| res.map(Into::into))
        .collect::<Result<Vec<_>, _>>()?
        .into_boxed_slice();  // Convert Vec into a boxed slice
    Ok(items.into())
}

Save and try the installation again.

You may encounter warnings like the following:

warning: unexpected cfg condition name: nightly
 --> cli\src\lib.rs:1:13
  |
1 | #![cfg_attr(nightly, feature(proc_macro_span))]
  |             ^^^^^^^
  |

For that, run the following code:

rustup toolchain install nightly
rustup default nightly

You may also encounter environment warnings after this. Just manually add the file path on your machine, like this:

win + R, type sysdm.cpl.

Go to the Advanced tab and click on Environment Variables. Under System variables, scroll down to find Path, then click Edit.

Add the file path:

C:\Users\Username\.avm\bin

Try the installation again.

Restart your terminal and verify installation with:

anchor --version

Answer 5

cargo install --git https://github.com/coral-xyz/anchor --tag v0.30.1 anchor-cli

Running this will solve the issue, as suggested by Jonas H.
