安装 rustup 后没有配置默认工具链

问题描述

我使用 rustup 安装了 Rust，但是当我尝试在控制台中输入像 cargo 或 rustc 这样的 Rust 命令时，出现以下错误:

I installed Rust using rustup, but when I try to enter a Rust command like cargo or rustc in my console, the following error appears:

error: no default toolchain configured

这是一个已知问题吗?

推荐答案

如果看起来 rustup 没有成功安装和配置 stable 工具链，您可以手动进行:

If it seems that rustup did not successfully install and configure the stable toolchain, you can do it manually:

rustup install stable
rustup default stable

经测试，我的安装不完整，可能是网络错误造成的.您也可以尝试重新安装以解决问题.

After testing, it seems like my incomplete installation may have been caused by a network error. You can also try to reinstall to solve the problem.
