【问题描述】：

配置文件app/config/parameters.ymlNEXT后报错，如何解决？

直接通过 composer 安装 symfony：

Generating autoload files
Would you like to install Acme demo bundle? [y/N] y
Installing the Acme demo bundle.
Creating the "app/config/parameters.yml" file
Some parameters are missing. Please provide them.
database_driver (pdo_mysql): 
database_host (127.0.0.1): localhost
database_port (null): 
database_name (symfony): curso_sf
database_user (root): 
database_password (null): @admin1
mailer_transport (smtp): 
mailer_host (127.0.0.1): localhost
mailer_user (null): 
mailer_password (null): 
locale (en): es
secret (ThisTokenIsNotSoSecretChangeIt): curso_sf!

[Symfony\Component\Config\Definition\Exception\InvalidTypeException]                                  
Invalid type for path "doctrine.dbal.connections.default.password". 
Expected scalar, but got object.  

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception

[RuntimeException]                                                         

An error occurred when executing the "'cache:clear --no-warmup'" command.

【问题讨论】：

它很可能不喜欢您密码中的@符号

@ 符号表示服务

【参考方案1】：

您必须通过将@@ 加倍来逃避@，如documentation 中所述：

parameters:
    # ...
    database_password : "@@admin1"
