[Php] windows下使用composer出现SHA384 is not supported by your openssl extension

composer的版本太低了,需要更新composer windows的安装使用 https://getcomposer.org/Composer-Setup.exe 报这个错Failed to decode zlib stream,把下面的composer.phar移动到php.exe所在目录,重试就好了

linux下用下面的命令行重新安装,windows下也可以用 php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php -r "if (hash_file('sha384', 'composer-setup.php') === 'a5c698ffe4b8e849a443b120cd5ba38043260d5c4023dbf93e1558871f1f07f58274fc6f4c93bcfd858c6bd0775cd8d1') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" php composer-setup.php php -r "unlink('composer-setup.php');" 可以直接把目录下的composer.phar移动到/usr/bin/composer

php的版本也要比较高的版本
