ParameterNotFoundException 已被删除，但我仍然得到错误？答案

【问题描述】：

我在一个 symphony 项目上运行 phpunit 时遇到了这个错误

Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException: You have requested a non-existent parameter "secret_parameter".

参数位于 .html.twig 文件中。我试图通过删除带有“secret_parameter”的行来抑制错误。

字符串“secret_parameter”不再在我的项目中。

但是，如果我尝试运行 phpunit，我仍然会遇到同样的错误。

这是为什么呢？

我曾尝试运行此行来清除缓存，但没有帮助：

php bin/console cache:clear

我的错误的完整堆栈跟踪是：

【问题讨论】：

我想您尝试完全删除 var（或应用程序）缓存目录，但似乎您仍然在某处潜伏着 secret_parameter。你所说的关于它在树枝模板中的说法非常令人困惑。确保您已经搜索了整个项目，包括应用程序和供应商目录。

【解决方案1】：

当你这样做时

php bin/console cache:clear

您正在清除开发环境的缓存。

Phpunit 使用测试环境。

你应该这样做

php bin/console cache:clear --env=test
