Question

我几周前在服务器上做了同样的事情，但现在我不能。这是我的错误输出：

composer install

Loading composer repositories with package information
Installing dependencies (including require-dev)
PHP Fatal error:  Uncaught exception 'ErrorException' with message 'proc_open(): fork failed - Cannot allocate memory' in phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.php:974

Answer 1

我曾经有过这个问题，增加内存限制解决了它。你可以尝试一下。

Answer 2

将composer.lock添加到跟踪文件解决了问题。

git add -f composer.lock
git add .
git commit -m 'remove composer.lock from ignored files'
git push

然后，

git clone ....

在服务器中。

问题解决了。

非常感谢。

Answer 3

如果您在虚拟环境（如vagrant）下运行，请确保已启用交换。在脚本下运行以创建交换

#!/bin/sh

# size of swapfile in megabytes
swapsize=512

# does the swap file already exist?
grep -q "swapfile" /etc/fstab

# if not then create it
if [ $? -ne 0 ]; then
   echo 'swapfile not found. Adding swapfile.'
   fallocate -l ${swapsize}M /swapfile
   chmod 600 /swapfile
   mkswap /swapfile
   swapon /swapfile
   echo '/swapfile none swap defaults 0 0' >> /etc/fstab
else
   echo 'swapfile found. No changes made.'
fi

# output results to terminal
cat /proc/swaps
cat /proc/meminfo | grep Swap

Answer 4

要解决此问题，请增加交换内存：

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

Answer 5

我在更新命令下遇到同样的问题解决了我的问题。

sudo作曲家自我更新

//这将设置内存。 php -dmemory_limit = -1 composer update

或

sudo php -dmemory_limit = -1 composer update

Answer 6

在更新具有大依赖性的symfony项目时遇到类似问题。创建交换文件有帮助： https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-12-04

Answer 7

要解决此问题，您必须运行2命令 shailesh @ ubuntu $ / var / www $ sudo / bin / dd if = / dev / zero of = / var / swap.1 bs = 1M count = 1024
输出将如下所示：
1024 + 0记录 1024 + 0记录输出 1073741824字节（1.1 GB）已复制，13.1359 s，81.7 MB / s

然后运行
shailesh @ ubuntu $ sudo / sbin / mkswap /var/swap.1
输出将如下：
设置交换空间版本1，大小= 1048572 KiB 没有标签，UUID = 486b676c-aa2a-4329-9783-6d1e6a9eb0a5

和最后的命令你必须运行
shailesh @ ubuntu $ sudo / sbin / swapon /var/swap.1

现在运行编辑器更新并节省时间。

Answer 8

这对我有用php -dmemory_limit=1GB $(which composer) update

Composer无法安装和更新
