Arch Linux

You need to enable phar.so in your php.ini.

ah i could have thought about that... can we add a notice for pacman after install?

But unfortunately there is more now:

PHP Warning: Phar::mapPhar(): open_basedir restriction in effect. File(/usr/bin/composer) is not within the allowed path(s): (/usr/bin/php:/srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/) in /usr/bin/composer on line 23
PHP Warning: require(phar://composer.phar/bin/composer): failed to open stream: phar error: invalid url or non-existent phar "phar://composer.phar/bin/composer" in /usr/bin/composer on line 24
PHP Fatal error: require(): Failed opening required 'phar://composer.phar/bin/composer' (include_path='.:/usr/share/pear') in /usr/bin/composer on line 24


seems like one also has to add "/usr/bin/composer" to the open_basedir (had this problem before with php executable ...)
guess it will become a longer notice ...
BTW: now it seems to run testet composer install with one production project

add /usr/bin/ to open_basedir and composer work fine

well of course one can add every binary, question is will this change be made from the package or will does it need to happen manually (with a notice after install)

@boscowitch and @Pierre

My solution was to copy /etc/php/php.ini to /etc/php/php-cli.ini, and empty the basedir variable.

This way php from command line will use /etc/php/php-cli.ini without restriction, but let me keep my /etc/php/php.ini with basedir for php-fpm or apache.

Is this a solution for you?

On a side not, the package I am prepareing for PHP 7 have no basedir setting and also include phar by default.

@Piere, you could split it, I'm testing this on my virtual arch server,
create a /etc/php/php.ini with the sane defauls and basedir restrictions, to used as default by apache or php-fpm
and create a /etc/php/php-cli.ini just for the cli tasks, like drush composer etc. this way the drush / composer packaged don't need to change,
because they will use /etc/php/php-cli.ini instead of the default.

I've had the same issue, adding /usr/bin to open_basedir in php.ini solved the problem.

How about setting open_basedir to make it work with composer by default?

As I said, open_basedir is no longer set with PHP 7.
