通过PHP运行时节点不起作用

PHP：

shell_exec(‘webpack -p –config /home/[username]/config/config.production.js 2>& 1’);

结果如下：

<--- Last few GCs --->

free -m给了我这个：

Swap:         5999          0       5999

vmstat给了我这个：

对我来说似乎没有任何明显的记忆问题？
如果我将webpack命令放入npm脚本,并从PHP运行,我会收到此错误:(但是从终端运行npm脚本也很好.)

npm ERR! path /home/[username]
npm ERR! code ENOMEM
npm ERR! errno -12
npm ERR! syscall scandir
npm ERR! ENOMEM: not enough memory,scandir '/home/[username]'
glob error { Error: ENOMEM: not enough memory,scandir '/home/[username]'
  errno: -12,code: 'ENOMEM',syscall: 'scandir',path: '/home/[username]' }

我假设这只是由Node抛出的相同错误.当我尝试从PHP运行任何其他NPM命令(如npm列表)时,我也会收到ENOMEM错误,这使我相信它只是一个节点问题而不是其他任何问题.

有谁知道发生了什么或为什么会发生这种情况？
