如何在 Kivy 啟動器中運行 kivy 1.9.1 應用程序？

Question

我用 Kivy 1.9.1-dev 編寫了一個簡單的應用程序。 當我想在 Andriod 2.4 設備上使用 Kivy 啟動器對其進行測試時，我得到了

[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)

並且該應用程序不起作用。 是否可以在 kivy 啟動器上測試使用 1.9.1 開發的應用程序？

kivy 啟動器日志是：

Answer 1

要回答您的直接問題，您需要使用 python-for-android 構建您自己的 kivy 啟動器版本（它具有指定此參數的參數）。

但是，如果您發布您的代碼，我們可以檢查它是否真的需要 1.9.1，並找出導致問題的原因。

Answer 2

您可以在代碼開頭指定 kivy 版本，如下所示：

import kivy
kivy.require("1.9.0")

Answer 3

升級你的 kivy 版本：

python3 -m pip install --upgrade kivy

然后加：

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

Answer 4

你在代碼的最上面寫 -

import kivy
kivy.require("1.9.1")
