00_Rust安装及Hello World
Rust官网: Rust安装官方的安装文档: [email?protected]:/mnt/d/code/rust_code$ curl https://sh.rustup.rs -sSf | sh info: downloading installer Welcome to Rust! This will download and install the official compiler for the Rust programming language,and its package manager,Cargo. It will add the cargo,rustc,rustup and other commands to Cargo's bin directory,located at: /home/u/.cargo/bin This path will then be added to your PATH environment variable by modifying the profile file located at: /home/u/.profile You can uninstall at any time with rustup self uninstall and these changes will be reverted. Current installation options: default host triple: x86_64-unknown-linux-gnu default toolchain: stable modify PATH variable: yes 1) Proceed with installation (default) # 继续安装 (默认) 2) Customize installation # 自定义安装 3) Cancel installation # 取消安装 >1 info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu' info: latest update on 2019-02-28,rust version 1.33.0 (2aa4c46cf 2019-02-28) info: downloading component 'rustc' 84.7 MiB / 84.7 MiB (100 %) 13.1 MiB/s ETA: 0 s info: downloading component 'rust-std' 56.8 MiB / 56.8 MiB (100 %) 13.5 MiB/s ETA: 0 s info: downloading component 'cargo' info: downloading component 'rust-docs' info: installing component 'rustc' 84.7 MiB / 84.7 MiB (100 %) 9.1 MiB/s ETA: 0 s info: installing component 'rust-std' 56.8 MiB / 56.8 MiB (100 %) 10.5 MiB/s ETA: 0 s info: installing component 'cargo' info: installing component 'rust-docs' 6.8 MiB / 8.5 MiB ( 80 %) 16.0 KiB/s ETA: 1.8390096028645833 min 50.3405761718 8.5 MiB / 8.5 MiB (100 %) 153.6 KiB/s ETA: 0 s info: default toolchain set to 'stable' stable installed - rustc 1.33.0 (2aa4c46cf 2019-02-28) Rust is installed now. Great! To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH environment variable. Next time you log in this will be done automatically. To configure your current shell run source $HOME/.cargo/env 安装完成后,在$HOME/.cargo/bin文件夹下可以看到如下的可执行程序(该目录默认会自动添加环境变量).
