我有一个带有一个小站点的macOS服务器,它使用say命令将文本片段转换为音频.

随着升级到Sierra,一切顺利,除了一件事：当我的PHP脚本中的exec()包装时,say命令不再起作用.

该页面刚刚超时.也没有发现任何错误.

<?PHP
    try {
        exec('/usr/bin/say "hello"');
    }
    catch (Exception $e) { echo $e->getMessage(); }
?>

通常我会使用say -o filename保存音频片段,但我尝试了所有变体以及其他正常工作的shell命令,包括在我的输出文件夹中创建文件.

有趣的是,如果我从命令行运行它,它可以工作 – 要么大声说,要么创建一个输出文件.

macOS Sierra有PHP 5.6.24所以我认为safe_mode不适用,righht？

我想强调的是,使用新操作系统,PHP或say命令的更改是最新的.是的我确实调查并尝试了不同的输出和stderr重定向,但脚本只是挂起.

在ActivITy Viewer中查看say命令(相当于顶层的GUI),我尝试对其进行采样,不确定它是否有帮助：

这些是统计数据：

从打开的文件和端口,我可以看到我将stdout和stderr都设置为/ PRivate / VAR / LOG / apache2 / error_log,但根本没有任何显示.

此外,试图通过更精细的运行捕获输出,但没有快乐,只是超时(脚本文件夹也是可写的)：

<?PHP   
    try {
        $pipes = array();
        proc_close(proc_open("say hi",array(0 => array("pipe","r"),1 => array("pipe",2 => array("pipe","r")),$pipes,dirname(__FILE__),null));
    } catch (Exception $e) { error_log($e->getMessage()); }
?>

更新：High Sierra是一样的.

最终更新：安装Mojave后,删除了大部分Server.app功能,我添加了MAMP来处理这个任务.如果你愿意,可以自己听听 – 这是在macspeaks.com.
