Question

我正在尝试构建scipy，我得到一个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!

有哪些方法可以提供cython来解决此错误？

Answer 1

Python setuptools解决了这个问题。

http://docs.cython.org/src/quickstart/install.html
easy_install cython或pip install cython

Answer 2

如果您尚未安装Cython，请使用：pip install Cython。但是，如果您确实像我一样安装了旧版本的Cython，那么这就是为我解决的问题：pip install --upgrade Cython
