rustup: Failed to uninstall on macOS 10.13.2

Uninstalling Rust via rustup failed with following message, even there still be the directory exists.

error: could not remove 'cargo_home' directory: '/Users/user/.cargo'
info: caused by: No such file or directory (os error 2)

Environment is

• macOS 10.13.2
• Bash

The following is what I did and step to reproduce.

MacBook-Pro:~ user$  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:

  /Users/user/.cargo/bin

This path will then be added to your PATH environment variable by modifying the
profile files located at:

  /Users/user/.profile
  /Users/user/.bash_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-apple-darwin
     default toolchain: stable
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

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 $HOME/.cargo/env
MacBook-Pro:~ user$  rustup self uninstall


Thanks for hacking in Rust!

This will uninstall all Rust toolchains and data, and remove $HOME/.cargo/bin 
from your PATH environment variable.

Continue? (y/N) y
