Welcome to the rustup.rs wiki!

troubleshooting

if you get a mysterious error: no default toolchain configured, make sure you define $RUSTUP_HOME, eg:

export RUSTUP_HOME=$HOME/.rustup

this was the root cause of brew install ripgrep failing with error: no default toolchain configured even though rust was properly installed, because brew redefines HOME during installation: see https://github.com/Linuxbrew/homebrew-core/pull/1762
