Error amending to shell profile

[werdl]

Problem

Upon downloading and running in a Github Codespace:

 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/codespace/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  /home/codespace/.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/codespace/.cargo/bin

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

  /home/codespace/.profile
  /home/codespace/.bashrc
  /home/codespace/.zshenv
  /home/codespace/.config/fish/conf.d/rustup.fish

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 standard installation (default - just press enter)
2) Customize installation
3) Cancel installation

error: could not amend shell profile: '/home/codespace/.config/fish/conf.d/rustup.fish': could not write rcfile file: '/home/codespace/.config/fish/conf.d/rustup.fish': No such file or directory (os error 2)

Upon creating the directory tree /home/codespace/.config/fish/conf.d, the error no longer happened. I am not sure why fish is being used - my $SHELL is /bin/bash

Steps

1. Instantiate a new Github Codespace
2. Go to rustup.rs and run the given command

Yup, I think that is #3706. We'll hopefully get a 1.27.1 release out soon that will have this fixed.
