Answer 1

这将删除任何已安装的Composer并为您正确安装：

sudo rm -f /usr/local/bin/composer
EXPECTED_SIGNATURE=$(curl -s https://composer.github.io/installer.sig)
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_SIGNATURE=$(php -r "echo hash_file('SHA384', 'composer-setup.php');")

if [ "$EXPECTED_SIGNATURE" == "$ACTUAL_SIGNATURE" ]
then
    php composer-setup.php --quiet
    rm composer-setup.php
    sudo mv composer.phar /usr/local/bin/composer
    sudo chmod 777 /usr/local/bin/composer
fi
