Failed opening required '__DIR__/composer/autoload_real.php about pico

[MaxGfeller]

You have to have PHP 5.3 installed to use the "DIR" magic constant:
http://php.net/manual/en/language.constants.predefined.php

To preserve compability with PHP 5.2 the developers would have to replace
"DIR" with dirname(__FILE__)

I uploaded Pico but I only see a blank php page of death. After turning on
error reporting, I get this:

Notice: Use of undefined constant DIR - assumed 'DIR' in
/hsphere/local/home/livenoma/writemorefaster.com/vendor/autoload.php on
line 5 Warning: require_once(DIR/composer/autoload_real.php): failed to

(include_path='.:/hsphere/shared/apache/libexec/php5ext/php/') in
/hsphere/local/home/livenoma/writemorefaster.com/vendor/autoload.php on
line 5

I figured I had the wrong version of PHP, but I just checked and am
running 5.2.10. Any ideas?

Here is my phpinfo: http://www.writemorefaster.com/test.php

Oh - it seems to be a composer problem. Since composer does not work with
5.2 it should be noted on the Pico home page somewhere.

Ah, that makes sense. The specs on the website need updating then, they claim Pico only requires 5.2.4+

But since the whole vendor directory is checked in directly in the Pico project, the end user does not need to run composer itself (which requires PHP 5.3). So if you would only update the AutoloadGenerator from composer, that would work in my opinion: https://github.com/composer/composer/blob/master/src/Composer/Autoload/AutoloadGenerator.php

So only Pico developers needed to have PHP 5.3 while the users still could use 5.2. But i don't know if the guys behind composer would merge that in.

[abely]

Is there a way to workaround the issue? My web host only has PHP version 5.2.17, and I am not a pico developer.

[MaxGfeller]

You could edit the vendor/autoload.php file manually and replace __DIR__ with dirname(__FILE__)

[abely]

Then I get

[19-Dec-2013 18:00:35] PHP Warning:  Unexpected character in input:  '\' (ASCII=92) state=1 in /home2/insweatc/public_html/pico/vendor/composer/autoload_real.php on line 23

[19-Dec-2013 18:00:35] PHP Parse error:  syntax error, unexpected T_STRING in /home2/insweatc/public_html/pico/vendor/composer/autoload_real.php on line 23

and my autoload_real.php looks like this:

<?php

// autoload_real.php @generated by Composer

class ComposerAutoloaderInit68d29614b81b64051229769b084d96b6
{
    private static $loader;

    public static function loadClassLoader($class)
    {
        if ('Composer\Autoload\ClassLoader' === $class) {
            require __DIR__ . '/ClassLoader.php';
        }
    }

    public static function getLoader()
    {
        if (null !== self::$loader) {
            return self::$loader;
        }

        spl_autoload_register(array('ComposerAutoloaderInit68d29614b81b64051229769b084d96b6', 'loadClassLoader'), true, true);
        self::$loader = $loader = new \Composer\Autoload\ClassLoader();
        spl_autoload_unregister(array('ComposerAutoloaderInit68d29614b81b64051229769b084d96b6', 'loadClassLoader'));

        $vendorDir = dirname(__DIR__);
        $baseDir = dirname($vendorDir);

        $map = require __DIR__ . '/autoload_namespaces.php';
        foreach ($map as $namespace => $path) {
            $loader->set($namespace, $path);
        }

        $classMap = require __DIR__ . '/autoload_classmap.php';
        if ($classMap) {
            $loader->addClassMap($classMap);
        }

        $loader->register(true);

        return $loader;
    }
}

Any idea?

I just found PHP 5.3 could be enabled on my host, and it is no longer an issue for me. Thanks all the same!

[jduerr]

Did anyone figure out how to get pico running on PHP 5.2?
I'd love to set pico up on our NAS. But an update to php 5.3 is available for that old box, sadly.
Already tried using MaxGfellers tip - get the Unexpected character in input warning like abely.

[cwiggs]

@jduerr FYI in case anyone else has this problem. I was having a problem with this with Dokuwiki, and found my way here. To fix that I just installed an older version of Dokuwiki. That same fix might work with Pico.

[ChamodyaDias]

running "composer update" command worked for me.(windows)

[PhrozenByte]

It's kinda weird that this Issue is actually the first Google result for this error message, even though Pico users won't experience it. Anyway, it's nevertheless a good idea to help all non-Pico users who seek help.

Welcome to the GitHub repository of Pico, a stupidly simple, blazing fast, flat file CMS. Even though you're here by chance, we might offer you a great alternative. Visit us at http://picocms.org/ and see http://picocms.org/about/ for more info. 👍

Depending on the actual error message you experience, the solution differs:

Notice: Use of undefined constant DIR - assumed 'DIR' in /var/www/html/…

Unfortunately I've to tell you that you can't run this application on your webserver 😞 To be more presice, you shouldn't run any application on your webserver. Your webserver runs a desperately outdated version of PHP (PHP 5.2 or earlier) that didn't receive any security updates since January 2011:exclamation:

Naturally nobody can't prevent you from doing it anyway. What will prevent you from doing it is the fact, that the application you're trying to install won't run on this outdated version of PHP and requires a newer PHP version. You will likely find the required PHP version in the application's README.md or install instructions.

There's no other solution than updating your PHP version.

Warning: require(vendor/autoload.php): failed to open stream: No such file or directory in /var/www/html/…

Please check your application's install instructions (maybe in its README.md), it looks like just uploading all of the application's files to your webserver isn't enough and you've to go through some more steps. Likely you'll have to open a shell, navigate to the desired install directory of the application and run composer install.

However, you really should check the application's install instructions 😉

Cannot find 'vendor/autoload.php'. Run `composer install`.

It looks like you're a Pico user and got lost 😃 You likely downloaded a Source code archive instead of one of Pico's release archives by accident. Just refer to Pico's install instructions and download the pico-release-[version].tar.gz archive instead of one of the Source code archives.

If Pico won't run nevertheless, you can join us on #picocms on Libera.Chat to get help. Alternatively, please don’t hesitate to create a new Issue on GitHub. Also see the "Getting help" section in Pico's docs.
