Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

I don't know what should I do. I had try COMPOSER_MEMORY_LIMIT=-1 composer.phar, but it not useful. And after I executed this command, composer gave instructions to help.

IIRC, you may need to create a temporary swap file.
See: https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors

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

The swap file will be removed when the machine is rebooted, or you can remove it manually.

daxpandhi Sorry, I dont know what should I do. Maybe my basic knowledge is lessful.

kecrily the problem is with the server RAM, there are different solutions depending on your kind of hosting:

The server might have enough memory, but PHP might not be allowed to use all of it. https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors explains how to change that by editing the PHP configuration files. This might be a setting in a dashboard if your hosting is shared/managed
If the server itself doesn't have enough memory, you can:
- Add swap, if the server is a VPS, following daxpandhi instructions
- Upgrade to a server with more RAM

Please share details about what kind of hosting you are using if you require further assistance.

clarkwinkelmann My server have enough memory. I had read the docs of composer and try.

If your server has enough RAM, you can increase the limit by editing the php.ini file

Run php --ini and look at Loaded Configuration File to see what configuration file is used by your CLI.

Then open it and search for memory_limit and edit it like:

memory_limit = -1 (-1 means unlimited, but you can also define an explicit value like 2G)
