Error “could not delete” with Composer on Vagrant

Question

I have a Vagrant running Linux and I\'m trying to install Symfony.

After the command composer create-project symfony/framework-standard-edition ./ \"2.5.*\"

Answer 1

Just got the same issue.

I see the problem in accessing to some local files. In my case target directory was under "root" and I'm not the root user.

Solution

Change permissions/owner of your files/directory.

1. Redefine owner:

   sudo chown myuser:myuser -R /path/to

2. Maybe there is some lack of permissions for group which you are in.
   So, try to run:

   sudo chmod g+rwX -R /path/to

Or maybe you may run your command with "sudo" if it works for you (not recommended). :)

P.S. Never use 777. It's not secure.

UPD1

Another thing, you may found out useful to solve the root of the cause, to wrap up your composer binary to run it always behalf a certain user.

$ cat /usr/local/bin/composer
#!/bin/bash

# run composer behalf www-data user

set -o pipefail
set -o errexit
set -o nounset
#set -o xtrace

[[ "${DEBUG:-}" = "true" ]] && set -o xtrace || true

composer_debug=$([[ 'true' != "${COMPOSER_DEBUG:-}" ]] || echo '-vvv' )

sudo -u www-data -- /usr/bin/composer ${composer_debug:-} $@
