php - 在WAMP环境中建立Concerto自适应测试平台时出错

我需要在WAMP环境中设置Concerto平台来开发自适应测试。到Concerto平台的链接在这里http://code.google.com/p/concerto-platform

这是我所做的事情：
1）设置WAMP Web服务器
2）设置R语言
3）设置本地主机并检查php，mysql和R的工作情况。

现在，在Concerto设置过程中遇到了问题，
特别是在本安装指南的倒数第二步之后
../concerto-platform/wiki/installation3

Concerto安装程序成功执行了php和mysql数据库的创建。
此后，Concerto安装程序无法按照下载文件../concerto-platform/downloads/list（zip文件3.8 MB）的安装要求运行安装脚本时识别R版本。

我已将Concerto源安装zip文件的内容提取到“ C：/ wampp / htdocs / concerto”目录中，并且安装脚本index.php位于“ C：/ wampp / htdocs / concerto / setup /”子目录中。

从浏览器（localhost / concerto / setup / index.php）运行安装脚本时，出现以下错误。
“注意：第97行中C：\ wampp \ htdocs \ concerto \ setup \ index.php中的未定义偏移量0。
R版本的安装必须至少为R> = v2.12。您的R版本是：v“

它无法获取和显示已安装的R版本，实际上是R v2.14
当我检查line97和引用的php函数时，我注意到以下代码片段。

public static function rscript_check()
{
    $array = array();
    $return = 0;
    exec("'" . Ini::$path_r_script . "' -e 1+1", $array, $return);
    return ($return == 0);
}

public static function r_version_check($version)
{
    $elems = explode(".", $version);
    if($elems[0]>2) return true;
    if($elems[0]==2)
    {
        if($elems[1]>=12) return true;
    }
    return false;
}

public static function get_r_version()
{
    $output = array();
    $return = 0;
    exec("'" . Ini::$path_r_script . "' --version -e 1+1", $output, $return);
    $version = substr($output[0],10);
    $version = substr($version,0,  strpos($version, " "));
    echo $version;
    return $version;
}

我的直觉是exec函数无法正常运行，因为我在start>中执行了等效的cmdline调用>运行“ Cmd / c G：/R/R-2.14.0/bin/Rscript.exe” --version -e 1 + 1”，并能够手动获取结果检查，但不能通过上述设置功能进行检查。我向协奏曲管理员询问，最近才开设了一个新的讨论论坛http://www.psychometrics.cam.ac.uk/page/343/discussion-forum.htm

因此，我在这里向SO社区寻求帮助。
非常感谢您设置此安装程序的任何指示。
PS：这是我在zip文件中提供的settings.php文件中输入的设置

根据您的个人经验或在WAMP / LAMP环境中快速安装协奏曲，您的任何想法和想法，我将不胜感激。我自己在Win XP上运行它。也许有人可以建议有关此主题的一些解决方法（如果exec确实是罪魁祸首，则可以在exec（）周围）。

万分感谢！

最佳答案

我有相同的配置，对我来说效果很好。
首先，我建议您使用R2.12而不是R2.14，您可以在此处获取它http://cran.r-project.org/bin/windows/base/old/2.12.1/

我还建议您通过更改“ R连接”部分来更改SETTINGS.php文件。
添加以下行

//R connection
$server_socks_type = "TCP"; // UNIX or TCP, choose TCP for any other OS than Linux
$server_host = "127.0.0.1"; //is socket server set to TCP, choose host to connect to
$server_port = "80"; //if socket server set to TCP, choose port used for connection
$r_instances_persistant_instance_timeout = 300; //after set period of instance inactivity in seconds the instance will be closed
$r_instances_persistant_server_timeout = 420; //after set period of server inactivity in seconds the server will be closed ( new instances can restart it anytime )
$r_max_execution_time = 30; //maximum R execution time ( prevents infinite loops in R on server )
$unix_locale = ""; //Unix locale LANG variable. Must be installed on the system. Leave blank for none/default.

使用WAMP时，您必须进行一些更改。

希望对您有帮助。
