如何手动安装和卸载 Rust？

Question

I'd like to try on a "hello world" program on Rust. I didn't choose rustup for auto-installation but downloaded the standalone installer . I thought I could follow the classic way to manually install it on Linux platform bundled with GCC and Clang below,

$ tar xf rust-xxx.tar.gz; mv rust-xxx $RUST_HOME 
$ cd /usr/local/bin; sudo ln -s $RUST_HOME/bin/rustc
$ rustc hello.rs; ./hello

However I found install.sh inside, so I have to run it for the installation, don't I? How to completely uninstall it afterwards?

Answer 1

I just downloaded the archive you linked and had a look inside the installation script.

During installation it will create an uninstall.sh script and actually print out for you the location:

install_uninstaller() {
    local _src_dir="$1"
    local _src_basename="$2"
    local _abs_libdir="$3"

    local _uninstaller="$_abs_libdir/$TEMPLATE_REL_MANIFEST_DIR/uninstall.sh"
    msg "creating uninstall script at $_uninstaller"
    run cp "$_src_dir/$_src_basename" "$_uninstaller"
    critical_need_ok "unable to install uninstaller"
}

#...


# Install the uninstaller
install_uninstaller "$src_dir" "$src_basename" "$abs_libdir"
