Problem with rust in apple silicon

help

Hello guys,
I have issue with open rust docs locally, I run this command:
rustup doc

and got this error message:

error: couldn't open browser

error: caused by: command 'open' did not execute successfully; exit code: 1

command stderr:

The file /Users/mehrdad/.rustup/toolchains/beta-aarch64-apple-darwin/share/doc/rust/html/index.html does not exist.

and in VsCode when I try to run my test program got this error when VsCode ask for install some rust package:

Executing task in folder test_test: rustup component add rust-analysis --toolchain beta-aarch64-apple-darwin <

info: component 'rust-analysis' for target 'aarch64-apple-darwin' is up to date

Terminal will be reused by tasks, press any key to close it.

The terminal process "/bin/zsh '-c', 'rustup component add rust-src --toolchain beta-aarch64-apple-darwin'" terminated with exit code: 1.

may please guide me to fix this, thank you

I can reproduce this problem. It looks like the rust-docs component is missing from the beta-aarch64-apple-darwin toolchain. It's also missing for the nightly channel. I don't know if this is a known bug.

I can't reproduce this error. The rust-src component installs successfully on my system. Try this command to update your toolchain, in case this was fixed recently:

rustup update

If that doesn't help, try uninstalling and reinstalling the beta toolchain:

rustup toolchain uninstall beta
rustup toolchain install beta

After uninstalling the toolchain, you might want to check whether the ~/.rustup/toolchains/beta-aarch64-apple-darwin directory still exists, and delete it if it does, just to make sure.

Tier 2 platforms do not build documentation.

as I check there is no path for html inside rust folder in this directory:

The file /Users/mehrdad/.rustup/toolchains/beta-aarch64-apple-darwin/share/doc/rust/html/index.html does not exist.

until rust directory is valid but after that is not.

Downloadable documentation is not available on Apple Silicon currently, because it is a Tier 2 platform.

So is there any way to build the doc on m1 locally?

You can clone the rust repo, install the required build tools, and build the docs from source with:

./x.py doc

Or you could download a pre-built toolchain that includes docs:

rustup install stable-x86_64-apple-darwin

and then run rustup +stable-x86_64-apple-darwin doc to open the docs (or copy/symlink the docs from the x86_64 toolchain into the aarch64 toolchain directory). Just be aware that there may be some minor differences between the x86_64 docs and the aarch64 docs.
