在laravel中使用symfony进程

Question

我想在控制器中使用它

$process = new Process('cd ../ && mkdocs build');
$process->run();
// executes after the command finishes
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);
}

错误抛出此

sh: 1: mkdocs: not found

如果我使用exec

 exec("cd ../ && mkdocs build", $out, $result);

它可以成功
