安装用C++编写的Python包(leven)时出错:g++无法识别的命令行选项--输出lib

Question

我一整天都在尝试安装这个Python库。它叫leven，你可以在这里找到它：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了错误。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，直到在运行命令时失败

C:Program Files (x86)CodeBlocksMinGWbing++.exe -mdll -static --entry _DllMain@12 --output-lib buildtemp.win32-2.7Releaselevenlib_levenshtein.a --def buildtemp.win32-2.7Releaseleven_levenshtein.def -s buildtemp.win32-2.7Releaseleven_levenshtein.o -LC:Python27libs -LC:Python27PCbuild -lpython27 -lmsvcr90 -o buildlib.win32-2.7leven_levenshtein.pyd
g++: error: unrecognized command line option '--output-lib'
g++: error: buildtemp.win32-2.7Releaselevenlib_levenshtein.a: No such file or directory
error: command 'C:\Program Files (x86)\CodeBlocks\MinGW\bin\g++.exe' failed with exit status 1

当我运行python setup.py安装时，整个过程是：

running install

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

我现在遇到了另一个问题。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，但我在implib=和name之间一直有一个额外的空白，我认为这就是程序停止工作的原因。对这个问题有什么想法吗？
