生成Python扩展失败(“kernel32.lib”无法打开,“x64”与目标计算机类型“x86”冲突)
我试图通过pip在新安装的Anaconda3上安装python扩展生成Python扩展失败(“kernel32.lib”无法打开,“x64”与目标计算机类型“x86”冲突),python,visual-studio,pip,compilation,python-extensions,Python,Visual Studio,Pip,Compilation,Python Extensions,我试图通过pip在新安装的Anaconda3上安装python扩展line profiler。由于该软件包需要编译器,我已经安装了VisualStudioBuildTools 2019以及Windows10SDK。特别是,我安装了 MSVC v142–VS 2019 C++-x64/x86构建工具(v14.27) Windows 10 SDK(10.0.18362.0) MSVC v141–VS 2017 C++-x64/x86构建工具(v14…) MSVC v140–VS 2015 C++构

pip install line-profiler
我收到了错误信息
fatal error LNK1104: file "kernel32.lib" cannot be opened
即使文件kernel32.lib
显然存在于上面添加到路径的一个文件夹中。(此问题末尾的完整错误日志)
经过一些研究,我发现在VS2019的开发者命令提示符下操作有助于解决这个问题,因为它会在启动时加载一些批处理文件。因此,我打开了这个命令提示符,激活了我的Anaconda环境,并再次运行相同的命令。现在我得到了错误
fatal error LNK1112: machine type "x64" is in confilict with the target machine type "x86".
如何设置VS以正确编译扩展?特别是,我想知道
kernel32.lib
问题在于并非所有环境变量都设置正确。要执行此操作,可以/需要执行文件
C:\ProgramFiles(x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\vcvars64.bat
。这(几乎)是在启动Develper命令提示符时完成的,这解释了为什么在这个控制台中可以找到kernel32.lib
出现第二个错误,因为Develper命令提示符不执行x64版本的脚本,因此将变量设置为x86编译器的路径。使用“VS 2019的x64本机工具命令提示符”(可在“开始”菜单中找到)解决了此问题。@ead您在哪里看到此问题?我已经安装了64位版本的Anaconda。为了再次检查,我测试了
sys.version
,它返回了3.8.3(默认值,2020年7月2日,17:30:36)[MSC v.1916 64位(AMD64)]
。很抱歉,我搞错了,您使用的是x86的构建工具,但x64 python只有一个版本的vs构建工具。它同时带有x86和x64工具。正如您在我的问题中所看到的,我已经将x64工具添加到路径中
