SensioLabsInsight kann nicht mit der Datenbank verbindet

Question

Ich versuche, meinen Symfony 3-Projekt zu überprüfen, aber ich erhalte eine Fehlermeldung mit dem Komponisten Skripte:

SensioLabsInsight was not able to install your Composer dependencies. If you need to customize files or run commands to make it work, you can edit your SensioLabsInsight project configuration to override the default "pre_composer_script" and/or "post_composer_script" settings.

Hier ist der Fehler:

I Ich weiß nicht, warum SensioLabsInsight eine Verbindung zur Datenbank herstellen muss.

Answer 1

Nach dem Löschen des Caches versucht Symfony, den Kernel zu booten. Dazu gehört auch die Verbindung zur Datenbank.

When installing your project's dependencies, the composer install command is executed. In turn, this command executes the cache:clear command, which tries to boot the kernel of your application.

Ich hatte das gleiche Problem und beschlossen, eine In-Memory-pdo_sqlite Datenbank in meiner Testumgebung zu verwenden (was ich schon woanders wurde mit), aber Sie können auch MongoDB, Redis verwenden, oder Memcached.

Answer 2

gleiche Problem für mich, apprently das Problem betrifft DBAL 2.5

So müssen Sie die Server-Version hinzufügen, in config.yml

doctrine: 
dbal: 
    driver: pdo_mysql 
    host:  "%database_host%" 
    port:  "%database_port%" 
    dbname: "%database_name%" 
    user:  "%database_user%" 
    password: "%database_password%" 
    charset: UTF8 
    server_version: 5.6
