I've gotten this notification:
The following modules are outdated:
Test_Test schema: current version - none, required version - 2.0.0
Test_Test data: current version - none, required version - 2.0.0
After running bin/magento setup:upgrade I got the error:
[Exception]
Warning: file_get_contents(var/di/setup.ser): failed to open stream: No such file or directory in .vendor/magento/framework/App/ObjectManager/ConfigLoader/Compiled.php on line 28
How can I solve this?
Deleting var/generation, var/cache and var/di solved it for me.
/var/page_cache var/generation, var/cache and var/di but issue not solved yet, tell me if you have another solution for the issue. Your need to only delete var/di folder by
rm -rf var/di/* Or delete folder manually
If still not worked delete var/generation and var/cache folder
rm -rf var/generation/*
rm -rf var/cache/*
Or delete folder manually
This seems to be a common issue, you can find more information here. https://github.com/magento/magento2/issues/4795
You can also try the following solution until it is fixed. https://github.com/magento/magento2/issues/4795#issuecomment-228610110
Run rm -rf pub/static/*; rm -rf var/view_preprocessed/*; php -f bin/magento setup:static-content:deploy instead. It clears multiple areas.
