无法使用Pip下载软件包：说明Cython未安装

Question

我正在尝试使用pip在我的Windows 10系统上下载pyahocorasick软件包。 在我的命令行上，我写了-

pip install pyahocorasick

它给出了以下输出-

^{pr2}$

然后我试着看看Cython是否真的安装了，所以我写了-

Cython version

结果是-

Traceback (most recent call last):
  File "C:\Python34\lib\runpy.py", line 170, in _run_module_as_main
    "__main__", mod_spec)
  File "C:\Python34\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "C:\Python34\Scripts\cython.exe\__main__.py", line 5, in <module>
  File "C:\Python34\lib\site-packages\Cython\Compiler\Main.py", line 28, in <module>
    from .Scanning import PyrexScanner, FileSourceDescriptor
ImportError: DLL load failed: %1 is not a valid Win32 application.

最后我试着-

install Cython

结果是-

Requirement already satisfied: Cython in c:\python34\lib\site-packages

所以我的问题是-如果Cython已经安装，为什么安装pyahocarasick包会出现错误-Cython does not appear to be installed？我怎样才能解决这个问题呢？在
