我正在编译python for arm，在我的ubuntu in virtual box上。在所有这些步骤运行之后，我将蟒蛇放在带有手臂处理器的机器上。我在终端运行命令"python"，得到一个错误，说它不能导入zlib。我在网上尝试了许多解决方案，但没有一个对我有效。唉，我最后的希望是把这个问题贴在这里。我能够让它在目标机器上工作，当这行:
rm -r lib2to3 idlelib lib-tk site-packages config lib-dynload
是这样写的:
rm -r lib2to3 idlelib lib-tk site-packages config lib-dynload distutils
我需要distutils，因为我想在机器上安装pip。我不能，因为我相信distutils依赖于zlib，但是我不能让python在为目标机器交叉编译后找到zlib。我正在运行Ubuntu 12.04.5。以下是我正在采取的步骤……

echo "Compilation complete (hopefully successfully). Now, connect to the Sandisk device's wifi hotspot,"
echo "and then run the local ./upload_python.sh script."
所以我知道哪里出了问题。我改变了
rm -r lib2to3 idlelib lib-tk site-packages config lib-dynload
rm -r site-packages config lib-dynload
另外，无论何时运行构建脚本，确保在每次运行开始时删除pybuild目录。在随后的运行中，pybuild目录仍然存在，由于某种原因，它删除了。so文件。
