Question

我安装了python 3.35，我收到了这个错误：

Traceback (most recent call last):
File "C:/Users/Augusto/PycharmProjects/Plot/Database.py", line 48, in <module>
import socket
File "C:\Python33\lib\socket.py", line 47, in <module>
import _socket
ImportError: DLL load failed: The specified module could not be found

我在Windows 7 64位上运行它。我尝试了两种Python安装（Windows x86-64 MSI安装程序和Windows x86 MSI安装程序），但两者都出现了相同的错误。我从路径中删除了python 2.7安装，导致错误，但没有运气。

编辑：os.system('listdlls %d' % os.getpid())

Answer 1

listdlls.exe的输出显示加载依赖关系ws2_32.dll（Winsock）没有问题，这至少可以说是令人惊讶的。所以问题是它试图加载错误的_socket.pyd。

在评论中确认，当绝对路径传递给imp.load_dynamic时，加载_socket.pyd有效。事实证明，系统将环境变量PYTHONPATH设置为包含C:\Python27\DLLs。解决方案是简单地取消设置此环境变量。

我被错误消息抛弃了。通常这种情况会引发一个错误，即为不同的Python版本编译共享库。但是，Python 2.7的_socket.pyd与msvcr90.dll链接。此DLL不在DLL搜索路径上。它位于%windir%\WinSxS的子目录中。通过查询C:\Python27\python.exe的激活上下文找到它，它在嵌入式清单中指定了C运行时依赖项：

<dependency>
    <dependentAssembly>
        <assemblyIdentity 
            type="win32" 
            name="Microsoft.VC90.CRT" 
            version="9.0.21022.8" 
            processorArchitecture="x86" 
            publicKeyToken="1fc8b3b9a1e18e3b">
        </assemblyIdentity>
    </dependentAssembly>
</dependency>

因此，当在C:\Python33\python.exe下运行时，尝试加载2.7 _socket.pyd会引发以下异常：

>>> imp.load_dynamic('_socket', r'C:\Python27\DLLs\_socket.pyd')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed: The specified module could not be found.

3.3和3.4是使用Visual Studio 2010而不是2008构建的，后者切换回在正常搜索路径上安装msvcr100.dll。所以为了比较，这是我尝试在3.4中导入3.3版_socket.pyd时得到的错误：

>>> imp.load_dynamic('_socket', r'C:\Python33\DLLs\_socket.pyd')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: Module use of python33.dll conflicts with this version of Python.

新鲜的python 3.3.5安装上的_socket模块导入错误
