第零章：实验环境配置步骤推荐

[CelestialMelody]

推荐的步骤：

1. Github Classroom方式进行在线OS 环境配置中的：1->2->3->4
2. Rust 开发环境配置
   • 通过rustc --version你会发现rust应该处于nightly版本，请不要切换为stable版本，否则无法中试运行 rCore-Tutorial中执行LOG=DEBUG make run
   • 若切换为 stable 版本，请使用 rustup override set nightly 与 rustup default nightly切换回nightly版本
3. Qemu 模拟器安装
4. 此时，你的控制台显示的位置应该在/workspaces/lab0-0-setup-env-run-os1-你的github名
   • 如果你是使用github的 codespace，请不要执行试运行 rCore-Tutorial中的git clone https://github.com/LearningOS/rust-based-os-comp2022.git，因为你已经clone到codeplace环境
   • 可以直接执行 make setupclassroom_testX （该命令仅执行一次，X的范围为 1-8）配置githubclassroom 自动评分功能。
5. 继续执行 cd os1 与 LOG=DEBUG make run，试运行 rCore-Tutorial

执行cargo install cargo-binutils --vers ~0.2时报错，报错信息显示

     = note: see issue #64926 <https://github.com/rust-lang/rust/issues/64926> for more information
     = help: add `#![feature(const_extern_fn)]` to the crate attributes to enable
     = note: this error originates in the macro `safe_f` (in Nightly builds, run with -Z macro-backtrace for more info)

For more information about this error, try `rustc --explain E0658`.

似乎是库出现冲突么？rust版本为rustc 1.62.0-nightly (1f7fb6413 2022-04-10)

太棒了 运行LOG=DEBUG make run出问题使用rustup override set nightly之后就解决了！

请问这个问题你解决了吗，我执行LOG=DEBUG make run的时候也遇到了类似的问题。
