这里有点问题..长话短说，我想在我的项目中实现Roboto字体，但我无法做到这一点（未能实现loadAsync）。所以我删除了所有导致Roboto的引用，启动了我的项目，这是我得到的消息。

• 已尝试删除node_modules并启动npm安装-不起作用
• 尝试使用VSCode中的搜索在文件夹中搜索Roboto-没有导致Roboto也尝试了其他一些事情，虽然现在不能重新调用它们。

如果你们能帮我解决这个问题，我将不胜感激，因为我花了太多时间来解决这个问题。

console.error: "fontFamily "Roboto_medium" is not a system font and has not been loaded through Font.loadAsync.

- If you intended to use a system font, make sure you typed the name correctly and that it is supported by your device operating system.

- If this is a custom font, be sure to load it with Font.loadAsync."
