Error: Cannot find module '@system.file'

如果你在快应用项目中遇到错误 "Cannot find module '@system.file'"，这可能是因为你没有正确引入文件系统模块。请按照以下步骤检查和解决问题：

1. 确保你的项目中已经添加了文件系统功能。在 `manifest.json` 文件的 `"features"` 对象中添加以下内容：

"features": {
  "filesystem": {}
}

2. 确保你已经正确引入了文件系统模块。在你的代码中添加以下代码：

const file = require('@system.file');

3. 确保你的项目已经安装了相关依赖。在终端中进入你的项目文件夹，并执行以下命令安装依赖：

npm install

4. 如果上述步骤都正确执行，但仍然无法解决问题，可能是因为你使用的快应用开发工具版本较旧。尝试更新快应用开发工具到最新版本。

如果问题仍然存在，请检查你的代码和项目配置是否正确，并确保你按照快应用文档中的指南进行操作。如有需要，你可以提供更多关于错误的详细信息，以便更好地帮助你解决问题。
