install php 7.4 and composer on ubuntu 18.04

install.txt

sudo apt-get update
sudo apt -y install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

sudo apt -y install php7.4
sudo apt-get install -y php7.4-{bcmath,bz2,intl,gd,mbstring,mysql,zip,sqlite,soap,imagick,curl,json,xml}

sudo apt install curl php-cli php-mbstring git unzip
curl -sS https://getcomposer.org/installer -o composer-setup.php
sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

sudo chown -R $USER ~/.composer/
composer global require hirak/prestissimo

I already had php installed so I only try install composer.
When I try this command "curl -sS https://getcomposer.org/installer -o composer-setup.php" , got this error "curl: (23) Failure writing output to destination".
Do you have any idea what could be?

You don't have write permission in the folder you are when run the command.
