我似乎能够连接到我的CPanel上的SSH并运行安装程序，但是访问"安装程序"失败，从而拒绝安装作曲家。什么好主意吗?

听起来好像在你的主目录中已经有一个名为"installer"的文件，但你没有权限写入。
使用以下命令
测试是否为这种情况ls -l | grep installer
建议的安装方法如下
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
