Installing via Mucho lead to some issues

[jacobcreech]

anchor % anchor build    
error: no such command: `+solana`

        Cargo does not handle `+toolchain` directives.
        Did you mean to invoke `cargo` through `rustup` instead?

Reinstalling solana did not fix my issue

[jacobcreech]

Seems to be common: https://solana.stackexchange.com/questions/7971/cargo-build-bpf-no-such-command-solana

Had to uninstall brew installed Rust. Brew install Rust in broken

brew uninstall rust

Had to uninstall brew installed Rust. Brew install Rust in broken

brew uninstall rust

maybe this has something to do with version issues of some type?

the "solana" toolchain should be installed via the solana-install command (which is used by the solana install shell script under the hood). do you have the solana toolchain on your system?

what is the output of the following command:

rustup list

[nickfrosty]

I wonder if brew install rust will nuke the existing rust toolchains you have on your computer? or if it manages the rust toolchains differently than rustup does?

[nickfrosty]

after some further research, it looks like brew install rust does not install rustup which is required by the solana install to fully configure the solana toolchain. see here for the source

so this does not appear to be a "mucho specific" issue, but rather a homebrew issue. mucho (naively) assumes rust is installed via rustup, since that is what the solana/agave/anchor docs all say to use.

we will have to improve the mucho install command to better understand this case, specifically that rustup is required and simply checking for rustc is not enough

edit: also opened an issue on the agave monorepo too: anza-xyz/agave#4651

Unfortunately I've already fixed my setup

Not sure, it's never worked for me

Seems like an odd requirement. Maybe there's a way we can install also with brew?

what do you mean here? meaning installing all the tools via brew for mac? or just rustup?

[jacobcreech]

Install rust up with brew

[nickfrosty]

The rustup installer script already works for all operating system. I just made this PR to always check if rustup is installed. in the next version of mucho, rustc and rustup are both checked and rustup will now be installed if the user does not have it, even if they already have rust installed

this also makes it so we do not need to perform any checks for user's having brew or not

note: the downside of that PR is that if a user already missing the solana toolchain due to already having run the solana installer without having rustup on their machine, no fix occurs to create the solana toolchain (aka platform tools). I am looking into how to manually fix this still and will add into mucho when I figure that out
