Possible solutions of your questions

Hello

potamu that need to access the file

for example

php composer.phar require etws/magento-language-ru_ru:dev-develop

the file composer.phar must be in the folder in which you are performing the command. can upload it to the folder.

instead of composer write php composer.phar

 php composer.phar   require etws/magento-language-ru_ru:* 

 php composer.phar   bin/magento cache:clean

where are you seeing this? we see something completely different

$ php composer.phar require etws/magento-language-ru_ru:*
./composer.json has been updated
