Laravel PHP Process无法运行节点

I am trying to build an angular project from a Laravel project.

When I run an exec command from Laravel I got env: node: No such file or directory

Steps to reproduce :

  1. create Laravel project: laravel new laravel-bug
  2. create angular project: ng new angular-bug

In the Laravel file routes/web.php, in the / route, add:

use Symfony\Component\Process\Process;
$process = new Process('cd /path/to/angular-bug && ng build');
$process->run(function ($type, $buffer) {
    if (Process::ERR === $type) {
        echo 'ERR > '.$buffer;
    } else {
        echo 'OUT > '.$buffer;
    }
});

This will output the result, which for me is env: node: No such file or directory

Any ideas ?

    I've had this issue before when node wasn't in the path of the web server user. The second argument to the Process::run() method is an array of environment variables. Use it to set a path.

    <?php
    use Symfony\Component\Process\Process;
    $env = ["PATH" => "/sbin;/bin:/usr/sbin:/usr/bin:/path/to/node/if/its/different"];
    $process = new Process('cd /path/to/angular-bug && ng build');
    $process->run(function ($type, $buffer) {
        if (Process::ERR === $type) {
            echo 'ERR > '.$buffer;
        } else {
            echo 'OUT > '.$buffer;
        }
    }, $env);
    

    The problem is that somewhere in this build process something is just calling node and expecting it will be in the path. (I think I experienced it when running npm.) This is not a great thing to do, and the software should be aware of where it’s located due to a compile-time setting or information from the package management system, or it should attempt to locate it.
