protoc-php.php requires protobuf extension installed to run
这让我摸不着头脑了。
时间过去了好久，没有发现任何突破，却发现了一个备用的解决这个问题的方案，修改/data/php_proto/文件夹权限为0775，其他普通用户就可以直接使用了，不用加sudo(这个是我的错，忘记修改文件夹权限了，这也让我发现了这个诡异的问题)
chmod -R 0775 /data/php_proto
看了报的这些错误，大部分都是扩展的问题，有的是扩展加载不成功，有的是扩展不存在，我就纳闷了，为什么普通用户可以，root用户就不可以。
看到root用户php -i的时候，配置文件的地方跟非root用户有不一致的地方：
//非root
Scan this dir for additional .ini files => (none)
Additional .ini files parsed => (none)
//root
Scan this dir for additional .ini files => /etc/php.d
Additional .ini files parsed => /etc/php.d/curl.ini,
......
命名加载的是一样的配置文件怎么加载之后的内容就不一样呢？
搜了半天，知道了报的错里面有部分是跟这个有关系的，但是这个在哪里修改搜了老久也没有搜到。
忽然想到root用户和非root用户使用的php可执行文件是不一致的
root => /usr/bin/php
非root => /usr/local/bin/php
尝试着对这两个文件使用了php -v，结果下了我一跳，root用户的版本是5.3.3，非root用户是5.4.6，呵呵，我就呵呵了，谁部署的环境~，坑人啊。
尝试着将原有/usr/bin/php备份后，复制/usr/local/bin/php过来覆盖掉，在使用php -v发现版本一致了，也不报错了，再次去执行php protoc-php.php -n --psr dmp.proto，发现all is well，至此问题解决。
纠结了半天，结果就是版本的问题。
