Composer無法安裝和更新

Question

幾周前我在服務器上做過同樣的事情，但是現在我做不到。 這是我的錯誤輸出：

作曲家安裝

Answer 1

我曾經遇到這個問題，增加內存限制解決了它。 您可以嘗試一下。

Answer 2

將composer.lock添加到跟蹤的文件即可解決此問題。

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

接着，

git clone ....

在服務器上。

問題解決了。

不管怎么說，還是要謝謝你。

Answer 3

如果您在虛擬環境（例如，vagrant）下運行，請確保啟用交換。 在腳本下運行以創建交換

#!/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

要解決此問題，請增加交換內存：

/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了相同的問題，解決了我的問題。

sudo作曲家自我更新

//這將設置內存。 php -dmemory_limit = -1作曲家更新

要么

sudo php -dmemory_limit = -1作曲家更新

Answer 6

在更新具有較大依賴項的symfony項目時也遇到了類似的問題。 創建交換文件有幫助： https : //www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-12-04

Answer 7

要解決此問題，您可以運行2命令。
shailesh @ ubuntu $ / var / www $ sudo / bin / dd if = / dev / zero of = / var / swap.1 bs = 1M count = 1024
輸出將如下所示：
1024 + 0條記錄中的1024 + 0條記錄輸出1073741824字節（1.1 GB）已復制，13.1359 s，81.7 MB / s

在那之后
shailesh @ ubuntu $ sudo / sbin / mkswap /var/swap.1
輸出將像：
設置交換空間版本1，大小= 1048572 KiB無標簽，UUID = 486b676c-aa2a-4329-9783-6d1e6a9eb0a5

最后的命令，你必須運行
shailesh @ ubuntu $ sudo / sbin / swapon /var/swap.1

現在運行作曲家更新並節省時間。

這對我php -dmemory_limit=1GB $(which composer) update
