Error Composer file put contents composer json failed to open stream Permission denied

Question

I'm trying to install Prestissimo , but that leads to an error:

$ composer global require "hirak/prestissimo:^0.3"
Changed current directory to /home/niroj/.composer


  [ErrorException]
  file_put_contents(./composer.json): failed to open stream: Permission denied


require [--dev] [--prefer-source] [--prefer-dist] [--no-progress] [--no-update] [--no-scripts] [--update-no-dev] [--update-with-dependencies] [--ignore-platform-reqs] [--prefer-stable] [--prefer-lowest] [--sort-packages] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--] [<packages>]...

I'm logged in as user kramer65, so I wouldn't know why it can't write to my home folder. My normal reaction to a permission denied is to use sudo, but composer then always says:

Do not run Composer as root/super user! See https://getcomposer.org/root for details

Any idea how I can solve this?

Answer 1

Hello @kartik,

It can be resolved with the following command:

$ sudo chown -R $USER ~/.composer/

Hope it works!!
Thank You!!

Answer 2

I used sudo and it managed to install laravel successfully

Don't ever use composer with sudo as it gives any installed packages root access to your project which can contain sensitive data.
