python - 安装用 C++ : g++ unrecognized command line option --output-lib 编写的 Python 包 (leven) 时出错

Question

我一整天都在尝试安装这个 Python 库。它叫做 leven，您可以在这里找到它:https://pypi.python.org/pypi/leven/ .

它是用 C++ 编写的，我在尝试构建和安装它时遇到错误。要构建和安装，我从命令行运行:python setup.py install。它运行其中的一部分，直到运行命令时失败

C:\Program Files (x86)\CodeBlocks\MinGW\bin\g++.exe -mdll -static --entry _DllMain@12 --output-lib build\temp.win32-2.7\Release\leven\lib_levenshtein.a --def build\temp.win32-2.7\Release\leven\_levenshtein.def -s build\temp.win32-2.7\Release\leven\_levenshtein.o -LC:\Python27\libs -LC:\Python27\PCbuild -lpython27 -lmsvcr90 -o build\lib.win32-2.7\leven\_levenshtein.pyd
g++: error: unrecognized command line option '--output-lib'

error: command 'C:\\Program Files (x86)\\CodeBlocks\\MinGW\\bin\\g++.exe' failed with exit status 1

当我运行 python setup.py install 时，整个过程是:

C:\Python27\Lib\site-packages>python setup.py install

这个问题的答案是用“-out-implib=name”替换“--output-lib name”。

我现在遇到了一个不同的问题。我需要在 cygwinccompiler.py 中将 --output-lib 更改为 -implib=name，这样当我调用该包的 python setup.py install 时它就会运行，但我不断得到一个额外的空格在 implib= 和名称之间，我认为这是程序停止工作的原因。对这个问题有什么想法吗？
