windows7在python中调用java安装pyjnius问题

[妤穆]

在windows7-32位安装了 python3.4 现在想在python中调用java

python34
mingw-get-setup.exe
Cython-0.25.1.tar.gz （Cython-0.25.1-cp34-none-win32.whl）两种都试过
pyjnius

1： mangw-32 在cmd中运行命令 gcc -v 是成功的，打印了如下：（ 安装了Basic SetUp的全部，除了mingw32-gcc-fortran，对应bin也加入系统Path中）

D:\>gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=d:/mingw/bin/../libexec/gcc/mingw32/5.3.0/lto-wrapper.exe
Target: mingw32
Configured with: ../src/gcc-5.3.0/configure --build=x86_64-pc-linux-gnu --host=m
ingw32 --prefix=/mingw --disable-win32-registry --target=mingw32 --with-arch=i58
6 --enable-languages=c,c++,objc,obj-c++,fortran,ada --enable-static --enable-sha
red --enable-threads=posix --with-dwarf2 --disable-sjlj-exceptions --enable-vers
ion-specific-runtime-libs --enable-libstdcxx-debug --with-tune=generic --enable-
libgomp --disable-libvtv --enable-nls
Thread model: posix
gcc version 5.3.0 (GCC)


2：D:\Program Files\Python34\Lib\distutils 创建文件distutils.cfg，内容如下：

[build]
compiler = mingw32

[build_ext]
compiler = mingw32

3、 安装Cython-0.25.1.tar.gz， python setup.py install,部分信息

4 安装 pyjnius， cmd : python setup.py install

D:\>cd D:\Program Files\kivy-pyjnius

5 、测试失败
测试文件testjava.py：
from jnius import autoclass

Stack = autoclass('java.util.Stack')
stack = Stack()
stack.push('hello')
stack.push('world')

print(stack.pop())
print(stack.pop())

报错信息：
"D:\Program Files\Python34\python.exe" E:/py/BondDjango/BondImplicitRate/testjava.py
Traceback (most recent call last):

求解，是哪个环节出问题了？

[妤穆]

在path中再配置个路径，指向jvm.dll ，然后报错：虚拟机启动失败，内存不够 E:\py\BondDjango\BondImplicitRate>python testjava.py Error occurred during initialization of VM Could not reserve enough space for object heap Traceback (most recent call last): File "testjava.py", line 1, in <module> from jnius import autoclass File "D:\Program Files\Python34\lib\site-packages\jniusx-1.0.5-py3.4-win32.egg \jnius\__init__.py", line 13, in <module> from .reflect import * File "D:\Program Files\Python34\lib\site-packages\jniusx-1.0.5-py3.4-win32.egg \jnius\reflect.py", line 14, in <module> class Class(with_metaclass(MetaJavaClass, JavaClass)): File "D:\Program Files\Python34\lib\site-packages\six-1.10.0-py3.4.egg\six.py" , line 808, in __new__ return meta(name, bases, d) File "jnius\jnius_export_class.pxi", line 43, in jnius.MetaJavaClass.__new__ ( jnius\jnius.c:17549) File "jnius\jnius_export_class.pxi", line 65, in jnius.MetaJavaClass.resolve_c lass (jnius\jnius.c:17957) File "jnius\jnius_env.pxi", line 11, in jnius.get_jnienv (jnius\jnius.c:3316) File "jnius\jnius_jvm_desktop.pxi", line 55, in jnius.get_platform_jnienv (jni us\jnius.c:3247) File "jnius\jnius_jvm_desktop.pxi", line 49, in jnius.create_jnienv (jnius\jni us.c:3173) SystemError: JVM failed to start 我用的IDE是pycharm, 修改pycharm.exe.vmoptions 文件分配内存大小都不行

对于在Python中调用Java不是特别熟悉，建议你试试jPython或者名为javabridge的python package
