## Composer FAQ
### I used the `composer` command and got a warning about not to run it as root.
Composer should be run as the web server user, usually `www-data` with Apache or `http` with nginx.
If you can't switch to the web server user using `su - [web user]`, you can directly run the Composer command with `sudo -u [web user]`.
### Running Composer with `sudo` complains about not being able to create the composer cache directory in `/root/.composer`
This is because `sudo` doesn't always change the `HOME` environment variable, which means that the command is run as the web server user but the system still uses `root` home directory.
