当我在 docker 上和所有配置文件中设置 mysql 时，Symfony 5 继续查看 postgre 数据库

Question

我是 Symfony 5.4/Docker 的新手，我正在尝试了解如何连接到 docker mysql 数据库。

我正在启动一个项目，其中我将使用在带有 Docker (mysql) 的远程计算机上运行的数据库。所以，我已经配置了这个数据库，并且我已经正确导入了其中的所有数据。所以我开始创建存储库和实体以推送到我的数据库中。

问题是当我在每个配置中设置 Mysql 时，symfony 继续看到 PostgreSql DB。但我有两件奇怪的事情。

1. 当我尝试将一些实体推入数据库时，出现此错误

2. 如果我执行

   symfony var:export

   ，我可以在环境变量中看到一些错误：

他继续将 Postgre 视为数据库。

怎么可能？ .env 文件

# In all environments, the following files are loaded if they exist,
# the latter taking precedence over the former:
#
#  * .env                contains default values for the environment variables needed by the app
#  * .env.local          uncommitted file with local overrides
#  * .env.$APP_ENV       committed environment-specific defaults
#  * .env.$APP_ENV.local uncommitted environment-specific overrides
#
# Real environment variables win over .env files.
#
# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE NOR IN ANY OTHER COMMITTED FILES.
# https://symfony.com/doc/current/configuration/secrets.html
#
# Run "composer dump-env prod" to compile .env files for production use (requires symfony/flex >=1.2).

Answer 1

您在这个项目及其周围使用过 postgres 吗？因为我也有类似的问题，但我的问题是因为我的机器上有一个处于活动状态的 Postgres 容器，所以我必须在 Symfony 使用我的 MySQL 连接之前停止它。根据记录，我不知道它为什么会这样做。
