Self-hosted runners fail composer setup if not root user

[lucasmdrs]

When using the setup-action on a self-hosted runner, the composer setup fails (without exiting) due to lack of permission.

Version

• I have checked releases, and the bug exists in the latest patch version of v1 or v2.
• v2
• v1

Runners

• GitHub Hosted
• Self Hosted

Operating systems

Docker/Ubuntu

PHP versions

Tested with 8.0.8, probably happening with every version

To Reproduce

Try to setup-php in a self-hosted agent without root user:

- name: Install PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: "8.0"
          ini-values: memory_limit=-1
          tools: composer:v2
          extensions: apcu, mongodb, redis, sockets, sodium

Expected behavior

Setup composer properly

==> Setup PHP
✓ PHP Installed PHP 8.0.8

==> Setup Tools
✓ composer Added composer 2.1.3

==> Setup Extensions
✓ apcu Enabled
✓ mongodb Enabled
✓ redis Enabled
✓ sockets Enabled
✓ sodium Enabled

==> Add php.ini values
✓ memory_limit=-1 Added to php.ini

==> Support this project
✓ setup-php https://setup-php.com/support

Additional context

There's a missing sudo in the tee command on commons.sh

setup-php/src/scripts/common.sh

Lines 235 to 238 in 0b33ef4

	if ! [ -e "$composer_json" ]; then
	sudo mkdir -p "$(dirname "$composer_json")"
	echo '{}' | tee "$composer_json" >/dev/null
	sudo chmod 644 "$composer_json"

But that might not solve the problem, not using sudo at all or ensuring that the folder is accessible by the current user would be a better approach.

Are you willing to submit a PR?

Yes, once agreed with one of the suggestions above.

Fixed in 36cb9fb
Now the composer's home directory will be owned by the current user, and that should fix this issue.
