【问题描述】：

我在使用 symfony 2.8 时遇到了这个错误，可能是 config.yml 中的错误，请帮助我解决这个问题并感谢高级

FileLoader.php 第 133 行中的 FileLoaderLoadException： 文件“/var/www/html/authenti/app/config/config.yml”在 /var/www/html/authenti/app/config/config.yml 中不包含有效的 YAML（从“/ var/www/html/authenti/app/config/config_dev.yml")。

代码 config.yml：

【问题讨论】：

嗯，这可能只是复制/粘贴问题，但所有部分（导入：、框架：等）都需要从最左边的列开始。您还应该在所有字符串周围使用单引号，尤其是使用 %parameter%。我怀疑您是否真的在进行任何测试之前就开始使用这些文件？可能想要回滚到以前的工作版本。

【参考方案1】：

尽量缩进，我看到这个例子来解决：

imports:
        -  resource: parameters.yml 
        -  resource: security.yml 
        -  resource: services.yml 

更正：

imports:
    -  resource: parameters.yml 
    -  resource: security.yml 
    -  resource: services.yml

很高兴为您提供帮助！

现在当我访问localhost/authenti/web/app_dev.php/login_check 我有这个结果，imgur.com/a/Mqs8E，这是真正的结果还是这是错误？？！请帮我解决这个问题
