Cant install magento2 with composer

[risunochki46ad]

I m trying to install magento with composer using my public and private key.

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition magento

But got error: 

The process "unzip -qq  '/var/www/html/magento/vendor/magento/magento2-base/........zip' -d '/var/www/html/magento/vendor/composer/421bd2d4'" exceeded the timeout of 300 seconds.
    The archive may contain identical file names with different capitalization (which fails on case insensitive filesystems)
    Unzip with unzip command failed, falling back to ZipArchive class

How to solve it?

Hi @risunochki46ad 

Try composer update/install -o -vvv and check weather the package is being loaded from composer's cache.
If yes try clearing composer's cache or try adding -cache-dir=/dev/null .

To force downloading an archive instead of cloning sources, use the --prefer-dist option in combination with --no-dev.

Otherwise you could try raising composer's process timeout value:

export COMPOSER_PROCESS_TIMEOUT=600   ( defaults to 300 )

It may help you to resolve issue.

As i understand --prefer-dists is used by default even without this parametr. And flag --dev 

is used by default too, i m downloading first time magento, i don't know may be i ll need some packkages from dev too. Anyway increesing of execution time has helped me. Thanks
