概述
环境文件设置工作流是一个初级难度的工作流。创建并验证本地开发用的 .env 文件，包含必需变量和安全检查以防止密钥提交。该工作流的目标是：Set up a local environment configuration file with all required variables for development.
环境准备
执行本工作流需要以下环境：A project that uses environment variables for configuration；A .env.example template file documenting required variables；Git repository with .gitignore。请确保在开始前准备好所有必需的工具和资源，以避免中途因环境问题中断。
执行步骤
本工作流包含4个步骤。步骤1：Copy template——Copy .env.example to .env to create a local configuration file. 步骤2：Fill in values——Replace each placeholder with the appropriate local value for your development environment. 步骤3：Verify .gitignore——Confirm that .env is in .gitignore to prevent committing secrets. 步骤4：Validate variables——Run the project startup command and verify that all required variables are recognized.
验证与清理
预期结果：A local .env file is configured with all required variables and is protected from accidental commits.。验证方法：Run git status and confirm .env is not tracked; start the application and confirm no missing variable errors.。清理操作：Never commit the .env file; if accidentally staged, unstage it immediately.。estimatedMinutes 为 10 分钟。
代码示例
cp .env.example .env
# Edit .env with your local values
grep ".env" .gitignore
