Getting "failed to open stream: No such file or directory in /autoload.php on line 5" when using Craft 3.4.0+ on site #6773

Closed aaronbushnell closed 4 years ago

aaronbushnell commented 4 years ago

Description

We're currently running a site on Craft version 3.3.4.1 and are updating to 3.5.8. However, we're receiving this error in our staging environment:

Warning: require_once(//composer/autoload_real.php): failed to open stream: No such file or directory in /autoload.php on line 5

Fatal error: require_once(): Failed opening required '//composer/autoload_real.php' (include_path='.:/opt/sp/php7.3/lib/php') in /autoload.php on line 5

It looks like this problem happens when I jump from 3.3.20.1 to 3.4.0 so something in 3.4.0+ is causing this issue in this environment.

Oddly enough, both autoload.php and autoload_real.php exist and this is not a problem in my local environment so not sure why this is occurring. Happy to provide a composer.json/lock file!

Additional info

brandonkelly commented 4 years ago

That is a Composer-generated file, so this is going to be due to an issue with the Composer install/update, not directly related to any Craft release.

Try nuking your vendor/ folder and then running composer install.

aaronbushnell commented 4 years ago

Hey @brandonkelly — yeah, unfortunately no dice with blowing away the vendor folder, composer.lock and even using Composer’s cache clearing command. It’s so strange. I can use the exact same dependencies in composer.json but the second I bump Craft to 3.4.0 I start getting this

andris-sevcenko commented 4 years ago

@aaronbushnell Can you try running composer dump-autoload?

aaronbushnell commented 4 years ago

Hey @andris-sevcenko! Here's the result of my tests:

✅ Works as expected

{
  "require": {
    "craftcms/cms": "3.3.20.1",
    "vlucas/phpdotenv": "^2.4.0"
  },
  "autoload": {
    "psr-4": {
      "modules\\": "modules/"
    }
  },
  "config": {
    "sort-packages": true,
    "optimize-autoloader": true,
    "platform": {
      "php": "7.0"
    }
  },
  "scripts": {
    "post-root-package-install": [
      "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
    ]
  }
}

Then I run: rm -rf vendor composer.lock && composer install

❌ Does not work

{
  "require": {
    "craftcms/cms": "3.4.0",
    "vlucas/phpdotenv": "^2.4.0"
  },
  "autoload": {
    "psr-4": {
      "modules\\": "modules/"
    }
  },
  "config": {
    "sort-packages": true,
    "optimize-autoloader": true,
    "platform": {
      "php": "7.0"
    }
  },
  "scripts": {
    "post-root-package-install": [
      "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
    ]
  }
}

rm -rf vendor composer.lock && composer install

This still does not work after I do composer dump-autoload.

Here's what I'm seeing when things are not working as expected:

FWIW I dropped a composer.phar at version 1.8.0 (the one I use locally) on the server and tried installing/dump-autoload with that and no dice still

brandonkelly commented 4 years ago

@aaronbushnell I’m not sure why it’s not working for you. I just tried your non-working composer.json file locally, and everything installed just fine. Have you tried on a different computer?

aaronbushnell commented 4 years ago

I have! It seems to only be happening on a ServerPilot+Digital Ocean server. No clue why that is. Anything you can think of that would make this occur with just the change to Craft v3.4+?

If so I can dive deeper and see if I can correct the problem/send a PR (if it’s relevant)

brandonkelly commented 4 years ago

Sorry, completely stumped. Composer doesn’t care about the contents of the packages it installs, so there’s really nothing Craft could be doing to mess it up if we tried.

Have you tried changing it to ^3.4.0 or ~3.4.0 ?

aaronbushnell commented 4 years ago

Okay, a bit more info here, but not sure what to make of it!

I went into the autoload_real.php file provided by Composer and started echoing out the files it's trying to load to see which of them throws the error. Here's what I get:

/app/vendor/composer/../symfony/polyfill-mbstring/bootstrap.php

/app/vendor/composer/../symfony/polyfill-intl-normalizer/bootstrap.php

/app/vendor/composer/../symfony/polyfill-php72/bootstrap.php

/app/vendor/composer/../symfony/polyfill-php70/bootstrap.php

/app/vendor/composer/../symfony/polyfill-intl-idn/bootstrap.php

/app/vendor/composer/../swiftmailer/swiftmailer/lib/swift_required.php

/app/vendor/composer/../voku/portable-utf8/bootstrap.php

/app/vendor/composer/../laminas/laminas-zendframework-bridge/src/autoload.php

Warning: require_once(//composer/autoload_real.php): failed to open stream: No such file or directory in /autoload.php on line 5

Fatal error: require_once(): Failed opening required '//composer/autoload_real.php' (include_path='.:/opt/sp/php7.3/lib/php') in /autoload.php on line 5

It looks like it has something to do with laminas-zendframework-bridge which makes sense as that was a dependency change added in 3.4.0-RC1! https://github.com/craftcms/cms/commit/4c37b37486ed9610927fa2529ef5a2003f2fa207

However, I still don't totally understand why this would be an issue. I'll reach out there to see if there's some info on this!

brandonkelly commented 4 years ago

Ah interesting, I didn’t realize laminas-feed was doing anything weird with autoloading. Looking into this on my end as well.

froschdesign commented 4 years ago

@brandonkelly Maybe I'm wrong but the problem lies much earlier:

Warning: require_once(//composer/autoload_real.php): failed to open stream: No such file or directory in /autoload.php on line 5

Fatal error: require_once(): Failed opening required '//composer/autoload_real.php' (include_path='.:/opt/sp/php7.3/lib/php') in /autoload.php on line 5

The autoload.php looks like this:

<?php

// autoload.php @generated by Composer

require_once __DIR__ . '/composer/autoload_real.php';

return ComposerAutoloaderInit196de3e2042c3dacfc824a5363515f20::getLoader();

And line 5 contains: require_once __DIR__ . '/composer/autoload_real.php';

The same problem arises also with a different configuration:

{
  "require": {
    "psr/http-factory": "^1.0"
  }
}

…because loading fails at all.

@aaronbushnell Can you recheck this?

aaronbushnell commented 4 years ago

Sorry not sure I’m totally tracking @froschdesign. Recheck what exactly?

I think this is isolated to the laminas-feed package! It was introduced in Craft 3.4 which is when this problem happens for me.

This is also happens if I setup a very minimal test case just using the laminas-feed package so I think it’s the culprit here. https://github.com/laminas/laminas-feed/issues/22#issue-694201516

froschdesign commented 4 years ago

@aaronbushnell The problem is line 5 in the file autoload.php. Craft CMS, laminas-feed or any other installed package via Composer is never reached.

Recheck what exactly?

With any other Composer configuration like this:

{
  "require": {
    "psr/http-factory": "^1.0"
  }
}
aaronbushnell commented 4 years ago

Ah, sorry, yes!

I tried changing the dependencies I had in package.json to use an earlier version of Craft CMS that didn’t use laminas-feed and it worked as expected.

Then, when I changed that version to 3.4.0 (the one that requires laminas-feed) it doesn’t work.

I know what you mean though. I thought it was a problem at a higher level but it appears the error message is a bit of a red herring here.

Notably because of this debugging process I took: https://github.com/craftcms/cms/issues/6773#issuecomment-687657018

It seems there’s nothing wrong with Composer loading packages in general. I can get it to load previous versions of the CMS but it’s when I pull in this particular package I start seeing the problem.

But I’m happy to run any debugging steps that might be useful for you! I have SSH access to the problematic server so happy to run any diagnostics that are useful.

weierophinney commented 4 years ago

So, I decided to try something to figure out what was going on.

I created a directory that contained the following:

I then ran composer install, followed by php test.php.

I had no autoloading issues. No errors at all. I even tried running on each of PHP 7.0 and 7.4 to see if there was any difference due to PHP version (I noted the "platform" configuration).

Can you indicate the exact PHP and Composer versions with which you observe the issues? And maybe provide the composer.lock that demonstrates the issue (as installing against that may help reproduce the issue)?

aaronbushnell commented 4 years ago

Yeah, same problem @weierophinney. Here's the full set of steps I've performed:

froschdesign commented 4 years ago

@aaronbushnell Please try an installation without Craft CMS or laminas-feed. You can use my example from above.

weierophinney commented 4 years ago

Okay, I noticed something pretty interesting in the above listings, @aaronbushnell: for some reason, the zend-stdlib, zend-escaper, and zend-feed libraries are being installed, and not the laminas equivalents. When I installed locally, I only received the Laminas libraries.

I'm wondering if this is a composer caching issue? Or are you using a non-public composer repository? Something is off between what @froschdesign and I are doing and what you're doing, and I think it's environment related.

Okay, thanks for the help, all! Here's some follow-up:

weierophinney commented 4 years ago

What environment is this running under? Those paths (e.g., //composer/autoload_real.php) are a bit wonky. Is this a docker container? Window? WSL?

What PHP version are you using? How is it installed (system packages, third-party repo like Remi or Sury repos, brew, something else)?

I'm honestly unable to recreate what you're observing, which again comes back to: I think it's an environment-specific issue. I want to help you resolve it, but I'm missing a key detail in here somewhere, as I just can't reproduce it.

One note. I dug into the laminas-zendframework-bridge package and it looks like there might be something happening here https://github.com/laminas/laminas-zendframework-bridge/blob/1.2.x/src/Autoloader.php#L69-L71.

This condition is firing, but I noticed that echoing getenv('COMPOSER_VENDOR_DIR') gives me nothing.

Is it possible this condition is being used (because /autoload.php is a file in this directory), but getenv('COMPOSER_VENDOR_DIR') is not being properly set? Not entirely sure here.

aaronbushnell commented 4 years ago

FWIW I can confirm that if I remove that conditional I no longer receive this error!

aaronbushnell commented 4 years ago

@weierophinney Maybe that condition needs to check that COMPOSER_VENDOR_DIR contains a value in addition to if the file exists?

weierophinney commented 4 years ago

That would explain the weird path for sure, @aaronbushnell , and could very well explain the behavior!

Would you be willing to submit a patch against laminas/laminas-zendframework-bridge to do that check, please? Ping me via a comment so I can review.

Thanks for doing the extra sleuthing!

aaronbushnell commented 4 years ago

Absolutely, thank you both, @weierophinney and @froschdesign! Here's the PR but please let me know if you'd like me to alter this in any way laminas/laminas-zendframework-bridge#71

brandonkelly commented 4 years ago

Nice detective work everyone! Will go ahead and close this now.

weierophinney commented 4 years ago

@aaronbushnell and @brandonkelly — We've just released version 1.1.1 of the bridge package. Please verify that it solves the problem; if it does, you should likely add the following to the craftcms package:

    "laminas/laminas-zendframework-bridge": "<1.1.1"
}

as that will ensure you get a version containing the patch always.

Thanks so much, @weierophinney!

@brandonkelly — is anything specific needed to inherit this fix on Craft 3.x projects? Do we need to be on the latest-and-greatest for this to work?

brandonkelly commented 4 years ago

@aaronbushnell Just run composer update.

Warning: require(/var/www/html/LaravelTest/vendor/autoload.php): failed to open stream: Permission denied in /var/www/html/LaravelTest/index.php on line 24

Fatal error: require(): Failed opening required '/var/www/html/LaravelTest/vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/html/LaravelTest/index.php on line 24

@Harshna-Patel That looks unrelated to the error in this issue. It’s saying PHP lacks the permissions to execute vendor/autoload.php. Perhaps you ran a Composer command as a root user or something like that. Please write into support@craftcms.com and we can help you resolve it from there.

to delete composer.lock, vendor and try 'composer install', worked for me

Try composer dump and composer clearcache

That is a Composer-generated file, so this is going to be due to an issue with the Composer install/update, not directly related to any Craft release.

Try nuking your vendor/ folder and then running composer install.

found another issue after running composer install, error is as:

Fatal error: Trait "Carbon\Traits\ToStringFormat" not found in /Applications/MAMP/htdocs/laravelprojects/newdocapp/vendor/nesbot/carbon/src/Carbon/Traits/Converter.php on line 36
