问题描述
在 buildozer 编译过程中，我在使用 python3 pip 或 hmac 时遇到了一些问题。
错误显示“xrange 未定义”，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。
如果我删除 .buildozer 文件夹进行干净的构建，它会按预期工作，并且 .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 制作的。 问题出在 hmac.py 的第 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。
网上冲浪我找到了一种解决问题的不同方法，通过 pip 下载“future”包并将以下行添加到 main.py
from past.builtins import xrange
但正如我所说，它适用于干净的构建，但在接下来的构建中失败。
我的目标是不要每次都进行干净的构建，因为过程太长。有什么想法吗？
解决方法
我有解决方案！
- 从 buildozer.spec 要求中删除“hmac”；
- 从here下载官方python3.7 hmac.py
- 将 hmac.py 放入您的 buildozer 文件夹中，可能位于名为“my_pkgs”的专用子文件夹中，然后以这种方式直接从您的 main.py 中导入它：
from my_pkgs import hmac
它在第一次干净构建期间完美运行，也适用于使用相同 .buildozer 文件夹发布的所有其他构建。 正是我正在寻找的。p>
[解决]是我的！
