Installation exits unexpectedly

Do you have suhosin installed? If so, does your config contain something like

suhosin.executor.include.whitelist = phar

Alternatively try running php -d error_reporting=E_ALL composer.phar to see if there are any hidden errors.

I too am not able to install composer. Here is what Im doing/seeing:

$ php composer.phar install

PHP Fatal error: Uncaught exception 'RuntimeException' with message 'The composer.json file could not be found in the current directory' in phar:///Users/xxx/composer.phar/bin/composer:37
Stack trace:
#0 /Users/xxx/composer.phar(15): require()
#1 {main}
thrown in phar:///Users/xxx/composer.phar/bin/composer on line 37

[naderman]

That is entirely unrelated. While that message isn't output nicely, it does tell you what the problem is. You have not created a composer.json file. Please see http://packagist.org for instructions on how to use composer.

I'm not running Suhosin. I got the same result with E_ALL and no error message was provided.

My configure looks like this:

[mikeyp]

Just for kicks, I tried to install with the default OS X PHP and received the same error as @evan108108 above.

[naderman]

That means it works correctly on OS X. Without a composer.json file Composer cannot know what to do. You must create one for your project before it can do anything.

Try the things mentioned here: http://silex.sensiolabs.org/doc/usage.html#pitfalls

[saltybeagle]

@mikeyp I think your first issue was caused by the detect_unicode PHP ini setting. You could try:

php -d detect_unicode=0 composer.phar install

@igorw linked a doc with details on how to permanently fix any CLI phar issues.

[Seldaek]

@saltybeagle can we do anything to detect this early in the phar bootstrap and warn the user? This is a really nasty error.

[stloyd]

@Seldaek Maybe adding check to stub ?

Composer\Compiler::getStub()

<?php

if (ini_get('detect_unicode')) {
    throw new \RuntimeException('Check your config, bro! ;-)');
}

[saltybeagle]

@Seldaek The error happens so early, I don't think it's something we can detect in userland code at runtime.

[Seldaek]

@mikeyp: I unfortunately can't reproduce it here. Could you try the fix @stloyd suggested, and then run bin/compile to get a phar and try again with that? It'd be cool if we can advise users to do the right thing.

[stloyd]

@Seldaek It seems we can't (as @saltybeagle mentioned) do this in userland. As I see you changed a bit error when composer.json is found, this should help to @mikeyp and @evan108108 (and other Mac'ers (tm)).

About issue with phar... I was think about making command (in bin/) that could run a check on php.ini and return some common pitfall warnings. But as mention, user must run it alone, we cannot do it in phar (or in stub as I suggested, this would fail on some OS [ubuntu works good, even when some pitfalls are detected as possible]).

It could look like:

bin/check_pitfalls

#!/usr/bin/env php
<?php

$errors = array();
if (false !== $unicode = ini_get('detect_unicode')) {
    $errors['unicode'] = 'On';
}

if (false !== $readonly = ini_get('phar.readonly')) {
    $errors['readonly'] = 'On';
}

if (false !== $hash = ini_get('phar.require_hash')) {
    $errors['require_hash'] = 'On';
}

if (false !== $suhosin = ini_get('suhosin.executor.include.whitelist')) {
    if (false === strpos($suhosin, ',') && $suhosin != 'phar') {
        $errors['suhosin'] = $suhosin;
    } else if (false === in_array('phar', explode(',', $suhosin))) {
        $errors['suhosin'] = $suhosin;
    }
}

if (false === empty($errors)) {
    echo 'Composer detected that you have enabled some settings in your';
    echo '`php.ini` file that can make Composer unable to work properly.';
    echo "\n\n";

    echo 'Make sure that you have changed options listed below:';
    echo "\n";
    foreach ($errors as $error => $actual) {
        switch ($error) {
            case 'unicode':
                echo "\rdetect_unicode = Off (actual: {$actual})\n";
                break;

            case 'readonly':
                echo "\rphar.readonly = Off (actual: {$actual})\n";
                break;

            case 'require_hash':
                echo "\rphar.require_hash = Off (actual: {$actual})\n";
                break;

            case 'suhosin':
                echo "\rsuhosin.executor.include.whitelist = phar (actual: {$actual})\n";
                break;
        }
    }

    exit(1);
}

[saltybeagle]

@stloyd That's an interesting proposal. I wonder if it would be worthwhile to cook up a simple install shell script (sort of like go-pear), which runs those simple checks, grabs the latest phar and sets up a bin/composer executable for the end-user.

[stloyd]

@saltybeagle I was thinking exacly about something like go-pear (maybe not exacly in .bat etc., just in php ;-) But this would lead to downloading, lets say, install_composer.php ;-) or something similar. Which would test userland for phar, php.ini, common pitfalls and maybe few others things :-)

@Seldaek, @naderman What do you think about such file ? I could make some work on php version if you would like this idea.

[Seldaek]

@stloyd: Would be great I think, if you can just send it to the composer/getcomposer.org repo, it should probably be there.
