rustup 没有安装工具链？

Question

恐怕对 rust 来说是个新手，无论如何，只是尝试为 aws cli 安装它..

我安装了 rustup 和 Cargo，但由于某种原因 rustup 拒绝安装工具链。它说它是最新的但未安装：

$ rustup --verbose toolchain install --force stable

(error: toolchain 'stable-i686-apple-darwin' is not installed, not a directory: '/Users/rich/.rustup/toolchains/stable-i686-apple-darwin')

$ rustup uninstall stable

$ rustup --verbose toolchain install stable
verbose: read metadata version: '12'

看起来 1.73.0 是我的 MacOS 10.11 中最后支持的版本，但这也不起作用：

rustup --verbose toolchain install 1.73.0

Answer 1

这是 MacOS 10.11 兼容性问题。我安装了 i686 版本的 rust-init，因此它想使用 i686 工具链，但最新版本似乎不存在该工具链。所以我用以下方法修复了它：

（1.73.0似乎是最新兼容的10.11版本）：

rustup --verbose toolchain install 1.73.0-x86_64-apple-darwin
rustup default 1.73.0-x86_64-apple-darwin
