rustup
を使うことにしました。
Rustのダウンロードとインストール
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | 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. Rustup metadata and toolchains will be installed into the Rustup home directory, located at: /home/fumo/.rustup This can be modified with the RUSTUP_HOME environment variable. The Cargo home directory is located at: /home/fumo/.cargo This can be modified with the CARGO_HOME environment variable. The cargo, rustc, rustup and other commands will be added to Cargo's bin directory, located at: /home/fumo/.cargo/bin This path will then be added to your PATH environment variable by modifying the profile files located at: /home/fumo/.profile /home/fumo/.bashrc 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 (default) profile: default modify PATH variable: yes 1) Proceed with installation (default) 2) Customize installation 3) Cancel installation >

Great! To get started you may need to restart your current shell. This would reload your PATH environment variable to include Cargo's bin directory ($HOME/.cargo/bin). To configure your current shell, run: source "$HOME/.cargo/env"
終わった。
rustc(Rustのコンパイラ)やcargo(Rustのツールチェーン)へ実行パスを通す
$ source "$HOME/.cargo/env"
ターミナルを閉じてもパスが通るよう、.bashrc
などに以下行を追加
export PATH="$HOME/.cargo/bin:$PATH"
動作確認
バージョン確認
rustcとcargoコマンド
$ rustc -V rustc 1.64.0 (a55dd71d5 2022-09-19) $ cargo -V cargo 1.64.0 (387270bc7 2022-09-16)
- こんなのが出ればOK。
