php - Composer 总是遇到 "Allowed memory size of 1610612736 bytes exhausted"- 在服务器和本地

Question

我在我的 Laravel 6 项目中使用 Composer 。但是，不知何故，我总是遇到问题“允许的内存大小为 1610612736 字节已用完”。我不知道为什么，但几天以来我遇到了这个问题，我不知道为什么或它来自哪里。
奇怪的是，我在开发服务器上遇到了完全相同的错误。这意味着它必须对 Laravel 项目本身做一些事情。因为正如我所说，在我的 Mac 和我的开发服务器上，我得到了完全相同的输出和完全相同的配置和项目。
唯一的解决方法是 php -d memory_limit=-1 composer update 。但是我无法在我的服务器上执行此操作，因为我不是服务器的管理员并且 RAM 使用量有限。所以，我确实想知道是什么导致了这个问题以及我如何解决这个问题。
除了下面的信息，您还需要更多信息吗？
我感谢任何形式的帮助!
亲切的问候和谢谢!

当我运行此命令时:
(基本上是我安装、删除或更新软件包的任何命令)

composer update
composer install
...

我得到以下输出:

当 composer 检测到 PHP 内存限制过低时，它会自动将内存限制增加到 1.5 GB。对于某些依赖集，这可能仍然没有足够的内存。
您可以通过在 composer 命令中内联指定 COMPOSER_MEMORY_LIMIT 环境变量来增加单个 composer 命令的内存限制。您可以将其增加到特定值，也可以将其设置为 -1 以消除内存限制，这样它就会尽可能多地用完。 注意:这不会改变服务器上的任何内容。这只会影响 Composer 对这一命令的内存限制。

COMPOSER_MEMORY_LIMIT=-1 composer install

如果您在执行此命令后仍然遇到内存问题，因为您的系统没有足够的可用内存，或者您需要人为地限制您的内存使用(您提到您有“有限的 RAM 使用”)，您可以尝试设置和使用交换文件以增加可用的内存量。
创建并启用临时交换文件:

# Create a 2GiB (1024x2M) empty file at ~/.swapfile
# This may take a minute.
dd if=/dev/zero of=~/.swapfile bs=1024 count=2M

# Setup a swap area in the new empty file.
mkswap ~/.swapfile

# Enable the swap area in the file (temporary - does not survive reboot).
swapon ~/.swapfile

现在，使用交换文件设置，运行您的 composer 命令。由于交换文件比 RAM 慢，这可能需要比您习惯的多一点时间。
完成 Composer 命令后，您可以根据需要禁用和删除交换文件。

# Disable the swap file
swapoff ~/.swapfile

# Remove the swap file.
rm ~/.swapfile
