Compilation zephir_解析器扩展未加载

我在ubuntu 14.04上运行，安装了php5.6。我正在尝试使用Hello world，但当我使用以下工具编译项目时：

zephir build

我得到了这个错误：

zephir_parser extension not loaded, compiling it
Parser statistics: 127 terminals, 99 nonterminals, 459 rules
                   947 states, 0 parser table entries, 0 conflicts

PHP Warning:  copy(modules/zephir_parser.so): failed to open stream: No such file or directory in /root/zephir/Library/Compiler.php on line 282
Zephir\Exception: The zephir parser extension could not be found or compiled!

有什么想法吗

编辑

我重新安装了这些软件包：

php5-json php5-dev libpcre3-dev

我尝试了以下命令行：

./bin/zephir compile

在编译时，我还有一个错误：

Copying new kernel files...
PHP Fatal error:  Call to undefined function Zephir\utf8_decode() in /root/zephir/Library/Compiler.php on line 2202

---

我通过使用

libpcre3 dev

重新安装php解决了我的问题，并安装了以下内容：

apt-get install php5.6-xml

解决utf8_decode（）上的致命错误
