【问题描述】：

我正在做一个小型测试项目，想将Robot Remoteserver 添加到 ios 设备上，但无法获得工具链来成功构建包。这是我尝试构建此软件包时遇到的错误：

对于找不到平台相关库这一行，我确实设置了 PYTHONPATH，但仍然出现此错误。

由于构建脚本没有可遵循的模板，我查看了 kivy 附带的包的构建文件并创建了一个包含以下内容的文件

from toolchain import PythonRecipe

class RobotRemoteServer(PythonRecipe):
    version = "master"
    url = "https://github.com/robotframework/PythonRemoteServer/archive/version.zip"
    depends = ["python"]


recipe = RobotRemoteServer()

我已确保 Kivy 及其所依赖的软件包都已正确安装。我也搜索了网络，但无法完全弄清楚问题所在。我正在使用 Xcode 6.4 和最新的 kivy 从 git 拉取。我已经坚持了几天，感谢任何帮助或指导。

Kivy 食谱遵循与python-for-android 相同的格式。 Here 你有相关的文档。
