【问题描述】：

我正在尝试根据以下说明构建 pynauty： https://web.cs.dal.ca/~peter/software/pynauty/html/install.html#build

我想指出我的主要目标是运行这个 python 代码： https://github.com/calebh/dihash

遗憾的是，我无法通过 pynauty 的制作阶段。如果我执行make pynauty 命令，我会收到以下错误：

cd nauty; make nauty.o nautil.o naugraph.o schreier.o naurng.o
make[1]: Entering directory '/home/pc/pynauty-0.6.0/nauty27rc5'

我猜上面是因为我没有安装python-dev 包（我想为python3构建if）。所以我为 python3 添加了一个别名： aliast python=python3。但是，当我在 pynauty 的根目录中键入 make 时，我仍然收到一条消息，说检测到 python2：

Available targets:

  pynauty       - build the pynauty extension module
  tests         - run all tests
  clean         - remove all python related temp files and dirs
  user-ins      - install pynauty into ~/.local/
  user-unins    - uninstall pynauty from ~/.local/
  virtenv-ins   - install pynauty into the active virtualenv
  virtenv-unins - uninstall pynauty from the active virtualenv
  dist          - create a source distribution
  docs          - build pyanauty documentation
  clean-docs    - remove pyanauty documentation
  nauty-objects - compile only nauty.o nautil.o naugraph.o schreier.o naurng.o
  nauty-progs   - build all nauty programs
  clean-nauty   - a "distclean" for nauty
  clobber       - clean + clean-nauty + clean-docs

Python version: 2 7 17
Machine type: x86_64

【解决方案1】：

编辑Makefile 为nauty。

将PYTHON = python 更改为PYTHON = python3，然后 PIP = pip 到 PIP = pip3（或任何你的 Python 3 的 pip 被调用）。
