我正在尝试从适用于 mac 的 SDK 构建我的 pebble 应用程序，但它不断给我以下错误。代码本身符合 cloud pebble 但由于某种原因给了我这个我无法理解的错误。

【问题讨论】：

混乱中的错误在以“RuntimeError:”开头的行中给出。该错误表明脚本在您的系统上找不到 Freetype 库。要修复它，我猜你必须下载并安装 Freetype 库。
以后，请尽量让你的问题标题更有意义。

【解决方案1】：

Simple-for-Pebble 使用自定义字体，因此您需要安装 Freetype 以便 Pebble SDK 能够处理 TTF 文件。

Pebble 开发者网站 (https://developer.getpebble.com/sdk/install/mac/#pebble-sdk-fonts-and-freetype) 上提供了有关如何执行此操作的说明，但安装它的最快方法是使用 Homebrew。

brew install freetype
