Cannot put magento 2 into production mode due to an error in setup:di:compile:

Question

We are trying to put a site into production mode but we get errors during the setup:di:compile step.

Below all the details I think are relevant:

Php 7.0.15

I have cleaned the cache with bin/magento cache:clean right before i executed the command.

When I try to run bin/magento setup:di:compile I get the following output:

Compilation was started.
Application code generator... 3/7 [============>---------------]  42% 55 secs 150.0 MiBPHP Fatal error:  Cannot declare interface Magento\Framework\DB\Adapter\AdapterInterface, because the name is already in use in /xxxxx/www/vendor/magento/framework/DB_bu/Adapter/AdapterInterface.php on line 15

Segmentation fault

We need the production mode because we are trying to optimise for better loading times.

Edit:

The error in the error log:

Answer 1

You have a directory called vendor/magento/framework/DB_bu that is causing the problem. My guess is that someone was making changes to the core files in vendor/magento/framework/DB and created DB_bu as a backup. That is what's causing the conflict so you need to remove this directory.

The vendor directory should not be tampered with. You should use a custom module to make changes.

Answer 2

You have an issue with FME_Extensions extensions.

Please disable all modules of that.

Then all should work fine.

Alternatively, you can also check var\log or var\report

Then run php bin/magento setup:di:compile

Answer 3

Try to disable all custom modules and reenable them step by step. This way you might find out which module is bugging and check if you can enable the others without getting this error. Dont forget to clear cache after disabeling and re-upgrading with console.

ANYHOW. You have an error with Renderer.php which indicates that the error appears when it is trying to inject or modify some sort of code, in your case a <script>-Tag.

This could be a XML problem, afaik. Have had the same problem with Renderer before on a bug for the layered navigation, so this maybe helps you, too.
