Buildozer 无法编译 .apk，因为未定义“xrange”

【中文标题】Buildozer 无法编译 .apk，因为未定义“xrange”【英文标题】：Buildozer fail to compile .apk because 'xrange' is not defined 【发布时间】：2021-04-13 11:22:29 【问题描述】：

我在 buildozer 编译过程中遇到了 python3 pip 或 hmac 的问题。

错误提示“未定义 xrange”，但仅当我在以前的 buildozer 文件夹 (.buildozer) 上编译时才会发生这种情况。

如果我做了一个干净的构建删除 .buildozer 文件夹，它会按预期工作，而且 .apk 也能正常工作。

我已经在 main.py 中添加了“xrange = range”

任何帮助将不胜感激。提前谢谢。

这是完整的构建器错误：

编辑：

问题在于 hmac，因为它是为 python2 设计的。问题出在 hmac.py 第 8 行和第 9 行：

trans_5C = "".join ([chr (x ^ 0x5C) for x in xrange(256)])
                                             ^
trans_36 = "".join ([chr (x ^ 0x36) for x in xrange(256)])
                                             ^

在 python3 中，'xrange' 已被删除并替换为 'range'。所以我试图在我的 main.py 中添加'xrange = range'，但它只适用于 buildozer clean 构建过程，而不是如果 .buildozer 文件夹已经存在，即使我构建了一个新的 .apk，它也适用于 clean构建但在第二次构建期间失败。

上网我找到了另一种解决问题的方法，方法是通过 pip 下载“未来”包并将以下行添加到 main.py
