Composer: file_put_contents(./composer.json): failed to open stream: Permission denied

Question

I\'m trying to install Prestissimo to an Ubuntu 16.04 server, but that leads to an error:

$ composer global require \"hirak/prestissimo:^0.3\"
Changed curren         


        

Answer 1

In my case, .composer was owned by root, so I did sudo rm -fr .composer and then my global require worked.

Be warned! You don't wanna use that command if you are not sure what you are doing.
