Magento 2 - Error on running update/cron.php

Question

I'm getting an error on running update/cron.php

I setup the cronjob according to the documentation. But it gives the following error:

PHP Warning: require_once(update/vendor/autoload.php): failed to open stream: No such file or directory in update/app/bootstrap.php on line 13

PHP Fatal error: require_once(): Failed opening required 'update/vendor/autoload.php' (include_path='.:') in update/app/bootstrap.php on line 13

I found that the path update/vendor/autoload.php is wrong. The autoload.php should be at /vendor instead. Is it a bug?

Answer 1

I finally figure out the issue. I have to run composer install at <magento_dir>/update/.

• tecjam: That is correct. But surely this should be done automatically when doing a composer install for magento2? Is this a bug? Still happens in 2.1.3
• Nagaraju Kasa: what kind of precautions we need to take care?

According to an internal Magento issue, that error indicates cron is running out of memory. Try increasing your PHP memory_limit to at least 1G; in fact, I believe we're going to start recommending 2G but that's not confirmed.

After you do that, restart your web server.

And by the way, sometimes you have two php.ini files: one for the PHP CLI and one for the web server plug-in. Change them both. See this to determine if you have one or two.

• fotfs: It is not a memory issue. The error said update/vendor/autoload.php does not exist
• Steve Johnson: This is the error I see in the internal issue. The cause is attributed to running out of memory: Warning: require_once(/magento2/update/vendor/autoload.php): failed to open stream: No such file or directory in /magento2/update/app/bootstrap.php on line 13
• fotfs: I have set memory_limit = 2G but still failed
• Steve Johnson: If you have two php.ini files, you must set memory_limit in both. If you rule that out, and you know autoload.php exists, then I don't know, sorry.
• fotfs: I have double checked and the memory limit is set correctly. But the error still happens.
