PHP 作曲家安装出现错误"??+?"

Question

我在尝试安装 PHP 作曲家时得到以下输出。有什么想法吗？

[user temp]$ curl -s https://getcomposer.org/installer | php -d detect_unicode=Off -d suhosin.executor.include.whitelist=phar
Some settings on your machine may cause stability issues with Composer.
If you encounter issues, try to change the following:
PHP was compiled with --with-curlwrappers which will cause issues with HTTP authentication and GitHub.
Recompile it without this flag if possible
Downloading...
Composer successfully installed to: /home/user/temp/composer.phar
Use it: php composer.phar
[user temp]$ php composer.phar install
??+?[user temp]$

修复了问题，这是一个权限问题！它在Jailshell中不起作用。
