PHP composer安装出现错误"??+?“

Question

当我尝试安装PHP composer时，我得到了以下输出。你知道哪里出问题了吗？

[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]$

修复了这个问题，这是一个权限问题！它在Jailshell中不起作用。
