我正在尝试为python2.7编译pypoker-eval-138.0库（默认在mint linux上）：
因此，当通过./configure运行configure脚本时，我得到有关python解释器版本的错误：
...snip...
checking for a Python interpreter with version =2.3... done
checking for a Python interpreter with version =2.4... done
checking for a Python interpreter with version =2.5... done
checking for a Python interpreter with version =2.6... done
configure: error: No python development environments found
我安装的python版本：
ls /usr/bin/python*
/usr/bin/python (/usr/bin/python -> python2.7)
/usr/bin/python2-dbg-config
/usr/bin/python2 /usr/bin/python3
/usr/bin/python2.7 /usr/bin/python3.3
/usr/bin/python2.7-config /usr/bin/python3.3m
/usr/bin/python2.7-dbg /usr/bin/python3m
/usr/bin/python2.7-dbg-config /usr/bin/python-config
/usr/bin/python2-config /usr/bin/python-dbg
/usr/bin/python2-dbg /usr/bin/python-dbg-config
我也尝试了./configure PYTHON="/usr/bin/python2.7"和类似但在上述问题上遇到了变体：
...snip..
checking whether to enable maintainer-specific portions of Makefiles... no
checking whether /usr/bin/python2.7 version =2.3... configure: error: too old
为了解决这个问题，我花了很多时间尝试更改aclocal / autoconf设置，但我不太熟悉应该做什么。我有以下.m4文件，我尝试编辑到不同程度的失败：
ls ./aclocal.m4 ./config/*
./aclocal.m4 ./config/install-sh ./config/ltsugar.m4
./config/ccpython.m4 ./config/libtool.m4 ./config/ltversion.m4
./config/config.guess ./config/ltmain.sh ./config/missing
./config/config.sub ./config/lt~obsolete.m4 ./config/py-compile
./config/depcomp ./config/ltoptions.m4 ./config/python.m4
例如，./config/ccpython.m4：
...snip..
AC_DEFUN([ALL_CC_PYTHON],
[
m4_define([_AM_PYTHON_INTERPRETER_LIST], [python2.6 python2.5 python2.4 python2.3])
PYTHONS=''
found_one=''
_ONE_CC_PYTHON([=2.3], [2_3])
if test -f "$PYTHON" ; then found_one=$PYTHON ; PYTHONS="$PYTHON $PYTHONS" ; fi
unset PYTHON
...snip..
我的问题是，具体来说：如何为2.7编译一个python模块，该模块的配置脚本最多只支持2.6？我是否必须重新生成配置脚本，或者我可以将一些标志或变量传递给配置脚本以强制构建2.7？
非常感谢！

好的，这是一个挑战（可以为声誉做些什么？：）。
提示在Changelog
中 * config/python.m4 (AM_PATH_PYTHON): Added python2.6 support.
* config/ccpython.m4 (ALL_CC_PYTHON): Added python2.6 support.
所以它应该只修复这些文件以支持新的python版本。我刚刚用python 2.7替换了python 2.5，用autoreconf重新配置并且它工作正常。请参阅下面的完整补丁。
要使其正常运行，请确保已安装这些软件包：
$ apt-get install python-dev autoconf pkg-config
应用下面的补丁并运行
$ autoreconf
$ ./configure
$ make
这是补丁（好吧，我也必须更改Makefile.am）：

您可以尝试从源http://www.python.org/download/releases/2.6.9/
安装python2.6或试用pyenv https://github.com/yyuu/pyenv
