为什么kivy无法导入kivy_clock

Question

https://kivy.org/doc/stable/api-kivy.app.html

import kivy
kivy.require('1.0.7')
from kivy.app import App
from kivy.uix.button import Button

class TestApp(App):
def build(self):
# return a Button() as a root widget
return Button(text='hello world')

if __name__ == '__main__':
TestApp().run()

根据上述代码，我有以下错误

我认为kivyclock和Cython有问题。

Answer 1

因为无论您安装了Kivy，都没有编译它或安装预编译版本。

你按照kivy.org的说明做了吗？

Answer 2

最终构建的apk完美运行&我在我的场景中找到了解决方法。

我在发现jdk8-devel&做了buildozer android清洁和问题发生。

修复：我只是在构建项目路径上使用命令rm -rf .buildozer删除了所有buildozer download|compiled|build。张贴它我再次使用buildozer -v android debug deploy run&一切都视为成功。因此，问题是错误的，需要删除的早期打包的构建模块|包。
