我需要在 WAMP 环境中设置 Concerto 平台来开发自适应测试。Concerto 平台的链接在这里http://code.google.com/p/concerto-platform
这就是我所做的:1)设置 WAMP 网络服务器 2)设置 R 语言 3)设置本地主机并检查 php、mysql 和 R 的工作。
现在我在安装 Concerto 的过程中遇到了问题,特别是在本安装指南的倒数第二步 ../concerto-platform/wiki/installation3 之后
Concerto 设置成功地执行了 php 和 mysql 数据库的创建。此后,Concerto 安装程序在运行安装脚本时无法识别 R 版本,如安装下载 ../concerto-platform/downloads/list(zip 文件 3.8 MB)中的建议
我已将 Concerto 源安装 zip 文件的内容提取到“C:/wampp/htdocs/concerto”目录,并且设置脚本 index.php 位于“C:/wampp/htdocs/concerto/setup/”子目录中.
当我从浏览器 (localhost/concerto/setup/index.php) 运行设置脚本时,我收到以下错误。“注意:第 97 行 C:\wampp\htdocs\concerto\setup\index.php 中未定义的偏移量 0。R 版本安装必须至少为 R >= v2.12。您的 R 版本为 :v”
它无法获取和显示安装的 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;
}
我的预感是 exec 函数无法正常工作,因为我在 start > run "Cmd /c G:/R/R-2.14.0/bin/Rscript.exe" --version -e 中执行了等效的 cmdline 调用1+1" 并且能够手动检查结果,但不能通过上述设置功能。我询问了 Concerto 管理员,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。非常感谢任何设置此安装的指针。PS:这里是我在 zip 文件中提供的 settings.php 文件中输入的设置

我将感谢您从您的个人经验或在您的 WAMP/LAMP 环境中运行快速协奏曲安装的任何想法和想法。我自己在 Win XP 上运行它。也许有人可以就这个主题提出一些解决方法(如果 exec 确实是罪魁祸首,则围绕 exec() )。
十分感谢!
