构建 scipy 错误 cythonize 失败

Question

我正在尝试构建 scipy，但出现 RuntimeError：

 $sudo python setup.py build
Processing scipy/cluster/_vq_rewrite.pyx
Traceback (most recent call last):
  File "tools/cythonize.py", line 172, in <module>
    main()
  File "tools/cythonize.py", line 168, in main
    find_process_files(root_dir)
  File "tools/cythonize.py", line 160, in find_process_files
    process(cur_dir, fromfile, tofile, function, hash_db)
  File "tools/cythonize.py", line 137, in process
    processor_function(fromfile, tofile)
  File "tools/cythonize.py", line 66, in process_pyx
    raise OSError('Cython needs to be installed')
OSError: Cython needs to be installed

Traceback (most recent call last):
  File "setup.py", line 209, in <module>
    setup_package()
  File "setup.py", line 202, in setup_package
    generate_cython()
  File "setup.py", line 147, in generate_cython
    raise RuntimeError("Running cythonize failed!")
RuntimeError: Running cythonize failed!

提供cython补救这个错误的方法有哪些？

Python setuptools 解决了这个问题。
