通过PHP运行时节点不起作用

2019年7月28日 108次阅读

我正在尝试创建一个运行webpack的简单
PHP脚本.当我在终端中运行它时,它运行正常,但是当我从PHP运行它时,会给我内存错误.这就是我的代码：

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：

                 total       used       free     shared    buffers     cached
Mem:         31956      29146       2810         51        947      24470

Swap:         5999          0       5999

vmstat给了我这个：

    procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu-----

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？

如果我能提供有关此问题的更多信息,请与我们联系.谢谢您的帮助！

最佳答案根据您提供的诊断信息,Web服务器环境正在以内存限制运行(可能通过setrlimit()系统调用).此调用允许进程限制允许它或其子节点分配的内存量.

您需要找到并更改相关设置以提高或禁用内存限制.
