Composer php admin/setup.sh：第2行：$'\r'；：找不到命令

尝试运行composer安装或composer更新时出错

我的环境是：VirtualBox、Vagrant、Centos7、PHP7.2

我已使用此方法安装composer：

cd /var/www/html/<project folder>
sudo yum install php-cli php-zip wget unzip
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
HASH="$(wget -q -O - https://composer.github.io/installer.sig)"

php -r "if (hash_file('SHA384', 'composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

sudo php composer-setup.php --install-dir=/usr/bin --filename=composer

谢谢你，谢谢你的帮助
