芹菜引发了意外的查找错误

Question

我正在为我的 Django 项目使用芹菜。

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])

这里的键是一个特征词列表。

使用 celery 执行时出现以下错误：

raised unexpected: 
           LookupError('\n\n===========================================================================\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，我想知道为什么还会出现这些错误？

Answer 1

我的环境是MAC.

问题是java_path，应该是：

java_path = "/your/Java/jdk/home

芹菜引发了意外的查找错误
