I want to modify one extension from public GitHub repository(fork), and install it to my Magento2 via composer.

Extensions stored here GitHub. Really, i need only one sample-external-links. I tried many times to configure composer.json in my Magento2 root, but it doesn't work, i receive errors:

[Composer\Downloader\TransportException] The "https://api.github.com/repos/magento/magento2-samples/sample-external-links" file could not be downloaded (HTTP/1.1 404 Not Found)

How to configure composer to install only 1 package from some repository like that?

my composer.json:

  • because it's just folder, not a repo

Each sample is packaged and available individually at repo.magento.com (The external sample isn't available individually). For convenience and demonstration of them bundling of modules, they have included the sample-bundle-all composer metapackage. Including this dependency in your Magento project is the more convenient way to integrate the full set of examples.

So to install the sample-bundle-all, run this command in your root installation folder.

composer config repositories.magento composer https://repo.magento.com/

Add the following code in the composer.json under the require section.

"magento/sample-bundle-all": "*"

And run:

alias mage="php -d memory_limit=-1 -f bin/magento"

chmod -R 775 pub/static/ var/ pub/media/ &&
rm -rf var/view_preprocessed/ var/cache/ var/page_cache/ var/tmp/ var/generation/ pub/static/frontend/ ;
composer install && composer update -vv && 
php -r "opcache_reset();"
mage cache:flush &
mage setup:static-content:deploy && 
mage indexer:reindex &
mage setup:upgrade &&
mage setup:db-data:upgrade &&
mage dev:source-theme:deploy &&
chmod -R 775 pub/static/ pub/media/ var/
