是否可以有多个并存的Rust安装? [英] Is it possible to have multiple coexisting Rust installations?

问题描述

是否有可能为了方便(每晚构建周期，自动更新)而每晚构建Rust编译器以及出于实验目的从GitHub克隆的Rust开发版本?

Would it be possible to have a nightly build Rust compiler for convenience (faster build cycle, auto-update) and a dev version of Rust cloned from GitHub for experimentation purposes?

这个想法是，我有一个用于我的各种项目的Rust二进制版本和一个我可以破解的Rust版本，而不会引起彼此之间的破坏.

The idea is I have a binary version of Rust for my various project and a version of Rust I can hack on, without them causing havoc between each other.

如果有关系，请假设我的操作系统是Ubuntu 64位.

If it matters, assume my OS is Ubuntu 64-bit.

推荐答案

当前的解决方案是使用 rustup .安装后，您可以安装多个工具链:

The current solution is to use rustup. Once installed, you can install multiple toolchains:

rustup install nightly
rustup install stable
rustup install 1.7

如果您具有Rust的本地版本，则可以链接作为工具链

If you have a local build of Rust, you can link it as a toolchain

rustup toolchain link my-development /path/to/rust/code

您可以选择一个默认工具链

rustup default stable

或仅通过rustup

cd /my/cool/project
rustup override set nightly

或通过

如果您只想暂时使用其他工具链，则可以使用"plus语法":

If you want to just use a different toolchain temporarily, you can use the "plus syntax":

rustc +1.7 --help
cargo +nightly build

在其他情况下，您可以使用rustup run在特定工具链中运行任意命令:

In other cases you can use rustup run to run any arbitrary command in a specific toolchain:

rustup run nightly any command you want here
