Celery引发了意外的查找错误

Question

我在django项目中使用了芹菜。

java_path = "/your/Java/jdk/home/java.exe
os.environ['JAVAHOME'] = java_path
st = POSTagger('/your/postagger/models/path/english-bidirectional-distsim.tagger','/your/postagger/jar/file/path/stanford-postagger.jar')

tag = st.tag([key])

这里的关键是一个特征词列表。

我在使用芹菜执行时出现了以下错误：

raised unexpected: 
           LookupError('nn===========================================================================nNLTK 
        `was unable to find the java file!nUse software specific configuration paramaters or set the JAVAHOME environment`

我已经设置了java_path和javahome，我想知道为什么仍然会出现错误？

Answer 1

我的环境是MAC。

问题是java_path，应该是：

java_path = "/your/Java/jdk/home
