Magento2: Magento upgrade from 2.2.6 to 2.3.0 fails with composer

Created on 29 Nov 2018 · 39Comments · Source: magento/magento2

I was trying to upgrade my Magento shop from 2.2.6 to 2.3.0 via composer. The installation failed with the message "Your requirements could not be resolved to an installable set of packages.". The problem seems to be the symfony/console component?

Preconditions (*)

Magento version 2.2.6
PHP version 7.1.9
Memory limit 768M
Max execution time 18000

Steps to reproduce (*)

Access the shell and jump to Magento root directory
Run "composer require magento/product-community-edition 2.3.0 --no-update"
Run "composer update"

Expected result (*)

All packages should be upgraded and all dependencies should be resolved correctly. The Magento upgrade should succeed by running the standard setup:upgrade etc. procedure after the composer update command

Actual result (*)

When running composer update the message "Your requirements could not be resolved to an installable set of packages." pops up
The actual error message goes on like this:

Hi @abcpremium. Thank you for your request. I'm working on Magento 2.2.6 instance for you

Unfortunately you can not test on the CLI using composer with these instances and there is only the update / upgrade wizard (which probably works).

@jcodo I tried it right now yes, but it didn't work either. Executing the script as explained on the site (php -f pre_composer_update_2.3.php -- --root='<path/to/magento/install/dir>') throws the following fatal error:

Fatal error: Uncaught TypeError: strtolower() expects parameter 1 to be string, integer given in /html/magento2/pre_composer_update_2.3.php:151

Saying "I have this problem too" and posting a long log output is not very helpful. Does anyone have a working solution / workaround for a PR?

Please upvote the initial issue comment.

@abcpremium I found that this is actually due to the repositories being labelled with "0", "1", "2" in composer.json. My only work arround currently, until this is fixed, is to rename these repos with names containing other characters (i.e. magento, etc.)

I found this two answers for this problem:

composer require --dev phpunit/phpunit:~6.2.0 friendsofphp/php-cs-fixer:~2.10.1 lusitanian/oauth:~0.8.10 pdepend/pdepend:2.5.2 sebastian/phpcpd:~3.0.0 squizlabs/php_codesniffer:3.2.2 --no-update
or
composer install
composer update

composer install
composer update

Recommended for PHP projects in general when something was changed in composer.json. So this alone with rm -rf vendor or just these 2 fixes your issue?

Sorry, I am not competent, I just found here the same issue.

Yes, this seems to be the issue. Was this different before?

DanielRuf on 30 Nov 2018

Hi @DanielRuf
Did you find a solution to this issue ? I have the same issue upgrading from CE 2.2.4

drdreamm on 1 Dec 2018

@drdreamm it was already mentioned, see https://github.com/magento/magento2/issues/19446#issuecomment-443134140

DanielRuf on 1 Dec 2018

So remove the vendor directory and using composer install & composer update should work? I'll test that one out as soon as possible.

abcpremium on 3 Dec 2018

Apparently this didn't work either for me. Even removing the composer.lock file from the Magento root directory and doing a fresh composer install with magento/product-community-edition 2.3.0 required in composer.json didn't work. The console output is the same as in my issue description.

abcpremium on 3 Dec 2018

I have about same issue but tried update Magento 2.2.7 to 2.3. Something quick idea to fix this problem?

can you send us your composer lock and json file?
manual upgrade process in https://devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html
should solve this problem..

cpartica on 3 Dec 2018

@DanielRuf @drdreamm @abcpremium Can you try running pre_composer_update_2.3.php with the additional option --repo=https://repo.magento.com/ and see if that solves your issue? Thanks

@pdohogne-magento You solution to add the repo as a parameter solved my issue. I was able to upgrade to Magento 2.3.0 fine now. Thank you for the tip!

Can you tell me full command what you use for this?

Userr017 on 4 Dec 2018

@Userr017 You should follow this chapter https://devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html

And this is my CLI:

php -f pre_composer_update_2.3.php -- --root='<path/to/magento/install/dir>' --repo=https://repo.magento.com/

Hi,

Did this php -f pre_composer_update_2.3.php -- --root='' --repo=https://repo.magento.com/

This got rid of the errors, but after that the Web Setup Wizard did the upgrade and after checking it was still the 2.2.6 version. Did I miss something?

KooTjoo on 5 Dec 2018

@KooTjoo it seems you didn't read https://devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html

Did you update the database schema and data?

php bin/magento setup:upgrade

phuongnd on 5 Dec 2018

@KooTjoo Well did you run the composer update command after executing the script? You need to do this in order to make composer actually download the new resources. Run your setup routine (setup:upgrade etc.) after that.

abcpremium on 5 Dec 2018

oops, sorry you are all right. Trying again.
