===============================================================================

OK! /Users/yvan/.zshrc has been modified. Restart your terminal for the changes to take effect,
or type ". /Users/yvan/.ghcup/env" to apply them in your current terminal session.

Editing ~/.zshrc (and ~/.profile) could fail (e.g. here because I use home-manager), so I believe the following code should better handle errors:

ghcup-hs/scripts/bootstrap/bootstrap-haskell

Lines 601 to 611 in e8cc1cc

	if [ -e "$HOME/.profile" ] ; then
	sed -i -e '/# ghcup-env$/d' "$(posix_realpath "$HOME/.profile")"
	printf "\n%s" "[ -f \"${GHCUP_DIR}/env\" ] && . \"${GHCUP_DIR}/env\" # ghcup-env" >> "$HOME/.profile"
	fi
	echo
	echo "==============================================================================="
