rust - 线程 'main' 在 'assertion failed: `(左 == 右 )` left: ` 2 2`, right: ` 4`' 安装 Rust for WSL 时 panic )

Question

我去网站上看到一个脚本来下载 Rust 安装程序:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

我在 Customize Installation 选项中更改了一些内容并继续安装，然后出现以下错误:

我还尝试使用 stable 作为默认安装，同样的事情发生在断言 (left == right) 上发生 panic 的地方。这可能是什么原因造成的？

Answer 1

这个问题在这里:https://github.com/rust-lang/rustup/issues/2245
问题:

microsoft/WSL#4898 seems to be the underlying cause; glibc has now implemented nanosleep in terms of clock_nanosleep, which depends on an unsupported WSLv1 codepath https://sourceware.org/ml/libc-alpha/2019-11/msg00155.html

解决办法是降级glibc。

This affects Arch Linux installation on WSL. The solution is to downgrade glibc:

pacman -U /var/cache/pacman/pkg/glibc-2.30-3-x86_64.pkg.tar.xz

上面的命令特定于为 Arch WSL 降级 glibc。我会为给定的 WSL 分发包管理器尝试类似的命令。
它看起来像 STEEL已经为 Ubuntu 提供了这样做的方法。
