问题描述
>>> import boilerpipe
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:Anacondalibsite-packagesoilerpipe\__init__.py", line 10, in <module>
jpype.startJVM(jpype.getDefaultJVMPath(), "-Djava.class.path=%s" % os.pathsep.join(jars))
File "C:Anacondalibsite-packagesjpype\_core.py", line 50, in startJVM
_jpype.startup(jvm, tuple(args), True)
RuntimeError: Unable to load DLL [C:Program FilesJavajre7inclientjvm.dll], error = The specified module could not be found.
at nativecommonincludejp_platform_win32.h:58
试过了:重新安装jvm
Tried: Reinstalling jvm
>> import ctypes
>> import os
>> os.chdir(r"<path to Java bin client folder>")
>> ctypes.CDLL("jvm.dll")
Still unable to fix
尝试下面的代码，仍然卡住:
Tried code below, still stuck:
从 py4j.java_gateway 导入 JavaGateway网关 = JavaGateway()它给出了与以前相同的错误.
from py4j.java_gateway import JavaGateway
gateway = JavaGateway()
It gives the same error as before.
推荐答案
请检查！
- 给出真实路径(
"C:\Program Files\Java\jre7\binclient\jvm.dll") - 检查所有 32 位或 64 位(我的报价始终使用 32 位 Anaconda、JRE7、Python 等)
- 安装pywin32(当然是python2.7.9)
- 授予
jvm.dll权限(可以运行) - 一切都ok了，试试:
import ctypesctypes.CDLL('C:\Program Files\Java\jre7\bin\client\jvm.dll')
- Give a true path (
"C:\Program Files\Java\jre7\binclient\jvm.dll") - Check all 32 or 64 bit (my offer always use 32bit Anaconda,JRE7,Python etc.)
- Install pywin32 (of course python2.7.9)
- Give permission to
jvm.dll(can run) - After all is ok, try:
import ctypesctypes.CDLL('C:\Program Files\Java\jre7\bin\client\jvm.dll')
***可能有些java版本的hook不能抛出我用 jre-7u55-windows-i586.exe
***Maybe can't throw the hook of some java versions
i used jre-7u55-windows-i586.exe
