生成脚本错误，cythonize失败

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!

提供cython来纠正这个错误的方法是什么?

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

如果您没有安装Cython，则使用:pip install Cython。但是，如果您像我一样安装了旧版本的Cython，那么这就是解决问题的方法:pip install --upgrade Cython

Answer 3

对于我来说，这个问题是由于不兼容的python + pandas版本，由于不正确的环境配置，尽管使用了Anaconda。通过pip安装Cython也可以工作，但这不是真正的解决方案。

Answer 4

我安装了Cython，但没有解决问题。我通过升级我的pip解决了这个问题:pip3 install --upgrade pip。
