Question

我安装了64位Windows 7和64位Python。

C:\Work\Python>python
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

我用这个安装了primesieve：

C:\Work\Python>pip install primesieve
Collecting primesieve
  Using cached primesieve-1.3.0-cp36-cp36m-win_amd64.whl
Installing collected packages: primesieve
Successfully installed primesieve-1.3.0

然后我尝试运行一个Python程序/脚本导入这个primesieve库但我收到此错误：

C:\Work\Python>run 500A

C:\Work\Python>python EulerProblem500A.py
Traceback (most recent call last):
  File "EulerProblem500A.py", line 1, in <module>
    import primesieve # pip install primesieve
  File "C:\Programs\Python36\lib\site-packages\primesieve\__init__.py", line 1, in <module>
    from primesieve._primesieve import *
ImportError: DLL load failed: %1 is not a valid Win32 application.

我不理解这个错误，因为OS，Python和primesieve库的版本都匹配。

有什么想法吗？！

Answer 1

查看源代码，您应该导入以下内容;

from libc.stdint cimport uint64_t, int64_t
from libcpp.vector cimport vector
cimport cpp_primesieve

好像是cython

<强>尝试：

pip install cython

ImportError：DLL加载失败：％1不是有效的Win32应用程序（主筛导入）
