Python 2.6 中的 Pylucene + MacOS 雪豹

Question

问候， 我正在尝试在 Snow Leopard 上运行的 32 位 python 上安装 Pylucene。我编译JCC成功了。但是我在制作 pylucene 时收到警告：

build of complete

然后我尝试导入 lucene：

有任何提示吗？

Answer 1

我必须调整 Makefile 中的第 44 行到 49 行才能正确安装 pylucene：

PREFIX_PYTHON=/my/virtualenv
ANT=ant
PYTHON=$(PREFIX_PYTHON)/bin/python
# add .__main__ to default configuration!
# --arch depends on your architecture of course
JCC=$(PYTHON) -m jcc.__main__ --shared --arch x86_64                                                                                                                                                                      
NUM_FILES=2

希望有帮助！

很难确定，但可能就像 jcc 没有安装在同一个 python 位置一样简单。为了排除故障，我会首先尝试直接使用 jcc。即使没有 lucene，这些命令也应该可以工作：

>>> import jcc
>>> jcc.initVM(jcc.CLASSPATH)
<jcc.JCCEnv object at 0x1004730d8>
>>> jcc._jcc.getVMEnv()
<jcc.JCCEnv object at 0x1004730f0>

顺便说一句，模块名称是 lucene，而不是 pylucene。
