PHP编写器更新“无法分配内存”错误（使用Laravel 4）

Question

我就是解决不了这个问题。

我在Linode 1G RAM的基本计划。试图通过Composer安装一个包，它不让我。我的内存限制设置为"-1"在PHP. ini

我还能做些什么来安装这个吗？

Answer 1

有点老了，但只是为了防止有新的人正在寻找解决方案，更新您的PHP版本可以解决这个问题。

此外，您还应该提交composer.lock文件，并在资源密集度较低的生产环境中安装composer。

Answer 2

作为作曲家故障排除指南，此处可能会发生这种情况，因为VPS运行内存溢出，并且没有启用交换空间。

free -m

要启用交换，您可以使用以下选项，例如：

sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1

或者，如果上述操作不起作用，则可以尝试创建交换文件

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Answer 3

看来你的交换内存用完了试试这个

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

正如@BlackBurn027在下面的评论中提到的，这个解决方案在这里进行了描述
