如何在kivy launcher中运行Kivy 1.9.1应用程序？

Question

我用Kivy 1.9.1-dev写了一个简单的应用。当我想在Andriod 2.4设备上使用Kivy launcher测试它时，我得到

[WARNING           ] stderr: Exception: The version of Kivy installed on this system is too old. (You have 1.9.0, but the application requires 1.9.1)

这个应用程序也不能工作。可以在kivy launcher上测试使用1.9.1开发的应用程序吗？

kivy启动器日志为：

Answer 1

为了直接回答你的问题，你需要使用python-for-android构建你自己版本的kivy launcher (它有参数来指定这个)。

然而，如果你发布你的代码，我们可以检查它是否真的需要1.9.1，并找出导致问题的原因。

Answer 2

您可以在代码的开头指定kivy版本，如下所示：

import kivy
kivy.require("1.9.0")

Answer 3

升级您的kivy版本：

python3 -m pip install --upgrade kivy

然后添加：

import kivy
kivy.require("versionkivy") #kivy.require("1.11.0")
