我在试着测试幽门烯库。我只为导入测试编写了这段代码。它不起作用。我得到了

bigissue@vmi995554:~/myluceneproj$  cd /home/bigissue/myluceneproj ; /usr/bin/env /usr/bin/python3.10 /home/bigissue/.vscode/extensions/ms-python.python-2022.16.1/pythonFiles/lib/python/debugpy/adapter/../../debugpy/launcher 36991 -- /home/bigissue/myluceneproj/hello_lucene.py 
Traceback (most recent call last):
  File "/home/bigissue/myluceneproj/hello_lucene.py", line 29, in <module>
    from org.apache.lucene.document import Document, Field, StringField, TextField
ModuleNotFoundError: No module named 'org'
bigissue@vmi995554:~/myluceneproj$

我已经运行了python3.10 -m pip list，并且有"lucene“模块。如果我导入lucene很好，但是python不识别org模块。为什么？

更新

我下载了Lucene9.1并设置了环境变量(/etc/environment)：

CLASSPATH=".:/usr/lib/jvm/temurin-17-jdk-amd64/lib:/home/bigissue/all_lucene/lucene-9.4.1/modules:/home/bigissue/all_lucene/lucene-9.1.0/modules" export CLASSPATH

我下载了幽门螺杆菌-9.1.0，并且我已经安装了第一个jcc

bigissue@vmi995554:~/all_lucene/pylucene-9.1.0$ pwd
/home/bigissue/all_lucene/pylucene-9.1.0/jcc
bigissue@vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py build
bigissue@vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py install

我还下载了ant apache。

然后pylucene 9.1 cd ..我有编辑Makefile vim /home/bigissue/all_lucene/pylucene-9.1.0/Makefile

PREFIX_PYTHON=/usr/bin
ANT=/home/bigissue/all_lucene/apache-ant-1.10.12
PYTHON=$(PREFIX_PYTHON)/python3.10
JCC=$(PYTHON) -m jcc --shared
NUM_FILES=10

bigissue@vmi995554:~/all_lucene/pylucene-9.1.0: make 
bigissue@vmi995554:~/all_lucene/pylucene-9.1.0: make install

如果我运行python3.10 -m pip，那么我就会看到它。

bigissue@vmi995554:~/all_lucene/pylucene-9.1.0$ python3.10 -m pip list | grep -i "lucene"
lucene                 9.1.0

现在我已经进口了lucene

import sys
from os import path, listdir
from lucene import * 

directory = RAMDirectory()

但我得到

ImportError: cannot import name 'RAMDirectory' from 'lucene' (/usr/local/lib/python3.10/dist-packages/lucene-9.1.0-py3.10-linux-x86_64.egg/lucene/__init__.py)
