我正在尝试在我的 cygwin 环境中buildozer android debug deploy。到目前为止，它运行良好，但在尝试构建时，我遇到了以下错误:

$ buildozer android debug deploy
# Check configuration tokens
# Ensure build layout
# Check configuration tokens
# Preparing build
# Check requirements for android
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/buildozer-0.15_dev-py2.7.egg/buildozer/targets/android.py", line 92, in check_requirements

ERROR: No suitable Java found. In order to properly use the Android Developer

We recommend that you install the JDK version of JavaSE, available here:

You can find the complete Android SDK requirements here:

有趣的是，如果我在 cygwin 中执行 java -version，它会返回

java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

所以 cygwin 确实知道 java。我在这里缺少什么？

编辑:好的，我尝试在第 92 行的 buildozer 的 android.py 文件中执行以下操作:

import cygwinreg as _winreg

但这只是给了我以下错误，而不是无法识别的 _winreg:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/buildozer-0.15_dev-py2.7.egg/buildozer/targets/android.py", line 92, in check_requirements

self.Close()

编辑2:

我已经设法解决了这个错误:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/buildozer-0.15_dev-py2.7.egg/buildozer/targets/android.py", line 92, in check_requirements

  File "/usr/lib/python2.7/site-packages/buildozer-0.15_dev-py2.7.egg/buildozer/targets/android.py", line 187, in _set_win32_java_home
with _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, r"SOFTWARE\JavaSoft\Java Development Kit") as jdk: #@UndefinedVariable
AttributeError: __exit__

编辑 3:

我已经将环境变量 JAVA_HOME 设置为我的 SDK 路径，所以这不是问题所在。我认为这是 winreg 无法正确导入该路径的问题。

编辑 4: 在一个叫 Gavin Bravery 的好人的帮助下，我现在不再遇到除 java 错误之外的其他错误。尝试时的当前输出

buildozer android debug deploy

是

有一个

export JAVA_HOME=$( cygpath "JAVA_HOME" )

我可以绕过路径警告，所以它归结为 “找不到合适的 Java”。错误。有人对此有想法吗？

最佳答案

您尝试在哪个操作系统版本上运行它？有时 cygwin 在 32 位操作系统上显示奇怪的行为。

关于java - Buildozer 不适用于 cygwin 下的 java，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23853363/
