make：在pkg-config搜索路径中找不到python软件包

Question

$ make
pip install runcython
Requirement already satisfied: runcython in d:\programfiles\conda\lib\site-packages
Requirement already satisfied: Cython>=0.10 in d:\programfiles\conda\lib\site-packages (from runcython)
makecython++ stitch_wrapper.pyx "" "stitch_rects.cpp ./hungarian/hungarian.cpp"
Package python was not found in the pkg-config search path.
Perhaps you should add the directory containing `python.pc'
to the PKG_CONFIG_PATH environment variable
No package 'python' found
stitch_wrapper.cpp:4:20: fatal error: Python.h: No such file or directory
 #include "Python.h"
                    ^
compilation terminated.
make: *** [all-python2] Error 1

尝试编译一些用C ++编写的utils，但出现此错误：

在pkg-config搜索路径中找不到python软件包。

Utils文件夹包含.cpp和.py文件（也使用Python进行处理）

我有python 3.6.1

make：*** [all-python2]错误1

似乎需要python 2。

但是我不确定在安装python 2. *并将其添加到系统变量后是否会消失。 谁能确定？

更新

尽管makefiles具有python 3行：

SHELL := /bin/bash

.PHONY: all-python2 all-python3
all-python2:
    pip install runcython
    makecython++ stitch_wrapper.pyx "" "stitch_rects.cpp ./hungarian/hungarian.cpp"

all-python3:
    pip3 install runcython3
    makecython3++ stitch_wrapper.pyx "" "stitch_rects.cpp ./hungarian/hungarian.cpp"

对我而言，在Arch Linux（4.15.11-1）上，makecython也无法找到python.pc 。 我检查了pkg-config --variable pc_path pkg-config ，发现相应的搜索路径仅包含文件python3.pc和python2.pc 。

所以我使用sudo ln -s /usr/lib/pkgconfig/python3.pc /usr/lib/pkgconfig/python.pc添加了一个符号链接，现在一切正常。
