ubuntu22安装最新版rustc并设置rustup、cargo清华镜像, 最后安装nushell_ubuntu升级 rustc

curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain stable -y --no-modify-path --profile default --component rustfmt
#这段无法镜像, 但貌似并不慢
#会提示 source ~/.cargo/env

#rust bin目录加到PATH
echo 'source ~/.cargo/env' >> ~/.bash_profile
 
# for bash
echo 'export RUSTUP_UPDATE_ROOT=https://mirrors.tuna.tsinghua.edu.cn/rustup/rustup' >> ~/.bash_profile
echo 'export RUSTUP_DIST_SERVER=https://mirrors.tuna.tsinghua.edu.cn/rustup' >> ~/.bash_profile
#参考: https://mirrors.tuna.tsinghua.edu.cn/help/rustup/

cat <<'OEF' >  ~/.cargo/config
[source.crates-io]
replace-with = 'tuna'
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index"
