NLTK 找不到 Java 可执行文件

NLTK fails to find the Java executable(NLTK 找不到 Java 可执行文件)

问题描述

我用的是NLTK的nltk.tag.stanford，需要调用java可执行文件.

I am using NLTK's nltk.tag.stanford, which needs to call the java executable.

我将 JAVAHOME 设置为安装 jdk 的 C:Program FilesJavajdk1.6.0_25，但运行程序时出现错误

I set JAVAHOME to C:Program FilesJavajdk1.6.0_25 where my jdk is installed, but when run the program I get the error

"NLTK was unable to find the java executable! Use the config_java() or set the JAVAHOME variable"

然后我花了3个小时调试它并尝试了

Then I spent 3 hours on debugging it and tried

config_java("C:/Program Files/Java/jdk1.6.0_25/")

config_java("C:/Program Files/Java/jdk1.6.0_25/bin/")
and those without the ending "/". 

但是 nltk 仍然找不到它.

However the nltk still cannot find it.

有人知道出了什么问题吗?非常感谢！

Anyone has idea about what's going wrong? Thanks a loooot!

推荐答案

如果设置 JAVA_HOME 环境对你没有帮助，试试这个:

If setting the JAVA_HOME environment doesn't help you, try this:

config_java() 对我不起作用.我将以下几行添加到我的代码中并且它起作用了:

config_java() did not work for me. I add the following lines to my code and it worked:

import os
java_path = "C:/Program Files/Java/jdk1.7.0_11/bin/java.exe"
os.environ['JAVAHOME'] = java_path
