在OSX上安装PyLucene JCC时出错

Question

我在Mac上安装PyLucene JCC有困难。

我从apache站点下载了最新版本的JCC，并使用命令解除了安装指令。

python setup.py build

但是我在安装时遇到了以下错误

ld: internal error: atom not found in symbolIndex(__ZN7JNIEnv_13CallIntMethodEP8_jobjectP10_jmethodIDz) for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'c++' failed with exit status 1

在运行安装命令之前，我尝试遵循官方站点上的指示，在mac上安装时添加标志"-framework", "Python" to the LFLAGS value，或者在运行安装命令之前使用export CFLAGS=-Qunused-arguments和export CPPFLAGS=-Qunused-arguments来忽略生成时的警告。但他们都不起作用。

错误的全部跟踪是

我现在真的迷路了，任何帮助都会是很棒的。

如果从源重新生成的结果仍然会产生相同的错误，那么您可能可以尝试以下方法。

似乎在OSX clang++ (引用的这里)上运行带有-x标志的-x命令(下面)有一个bug。

cc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -DENABLE_DTRACE -DMACOSX -    DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE -dynamiclib -D_jcc_lib -DJCC_VER="2.    21" -I/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/include -I/Library/Java/JavaVirtualMachines/jdk1.7.0_45.    jdk/Contents/Home/include/darwin -I_jcc -Ijcc/sources -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c jcc/sources/JCCEnv.    cpp -o build/temp.macosx-10.10-intel-2.7/jcc/sources/JCCEnv.o -DPYTHON -fno-strict-aliasing -Wno-write-strings

在不带clang++标志的情况下再次运行-x命令，然后运行：

python setup.py build

Answer 2

这里也有同样的问题-来自pyLucene-dev：

您必须确保用于构建Python的编译器与所使用的编译器相同。如果您没有构建Python，那么很可能是因为clang/gcc不匹配，您需要从源代码中重新构建Python，使用与构建JCC相同的编译器。

clang问题被固定为给定的这里。然而，PyLucene的最新版本(2018年5月)(V6.5)并没有推出它。但是，您仍然可以从这链接获得Pylucene的下一个版本(v7.2)。使用Pylucene 7.2.0为我解决了这个问题。
