无法 运行 Symfony 中的任何进程命令
Cannot run any process command in Symfony
我正在尝试 运行 Symfony 5.1 中的 linux 进程,如下所述:
https://symfony.com/doc/current/components/process.html
use Symfony\Component\Process\Process;
(...)
$command = 'echo hello';
$process = new Process([$command]);
$process->start();
foreach ($process as $type => $data) {
if ($process::OUT === $type) {
echo "\nRead from stdout: ".$data;
} else { // $process::ERR === $type
echo "\nRead from stderr: ".$data;
}
}
无论我的命令行是什么,我都会得到以下输出:
Read from stderr: sh: 1: exec: echo hello: not found
在您提到的文档中,您可以看到示例:https://symfony.com/doc/current/components/process.html#usage
$process = new Process(['ls', '-lsa']);
进程构造函数的源代码:
https://github.com/symfony/symfony/blob/5.1/src/Symfony/Component/Process/Process.php#L132
第一个参数是:
* @param array $command The command to run and its arguments listed as separate entries
尝试$process = new Process(['echo', 'hello']);
而不是$process = new Process(['echo hello']);
