我希望得到诊断方面的帮助。PyPi软件包vmprof无法在64位Windows 7机器上安装
错误消息指出可能无法在64位机器上安装此软件包，或者选择了错误的编译器。
编辑： 的requirements为vmprof状态，它将仅在x86（32位）上运行。很明显，应该指示C编译器将源代码编译为32位。这是否意味着vmprof包装中的缺陷应该作为vmprof问题提出来？
结束编辑。
无论哪种方式，我不知道如何解决这个问题。我从命令行运行pip install vmprof。
警告C4311：This warning detects 64-bit pointer truncation issues.
警告C4312：This warning detects an attempt to assign a 32-bit value to a 64-bit pointer type
这两个警告使我怀疑，如果PyPI将不能vmprof安装到我的64位环境。但是，如果所呈现的错误输出按时间排序，那么在生成这些警告后，Visual Studio就会加载。这是否指向正在使用的错误编译器？从2005年起，我确实有一大组Microsoft Visual C++ YYYY可再发行组件用于32位和64位。 （我不愿意通过卸载旧版本来测试错误的编译器理论，以防破坏某些东西）。
PyPi说它试图加载Microsoft Visual Studio v14.0，我相信它是Python 3.5的正确版本。
有other SO questions有关的警告，“manifest_maker：标准文件'-c'未找到” 我的setuptools是完全最新的。 （v 25.0.0）。 vmprof不可用作建议链接的预建二进制文件。无论如何，所有的二进制文件都不受支持。 有关此警告的其他SO问题与Unix有关。
警告LNK4197：export 'PyInit__vmprof' specified multiple times; using first specification. 这是构建最终似乎脱离轨道的点。我猜测“导出”PyInit__vmprof'“的多个规范在作为vmprof的一部分提供的命令文件中。
在这里坠毁的链接错误。完整的pip安装输出如下。

目前这个问题是固定的。而'conda install -c conda-forge vmprof'中的vmprof 0.4.9适用于我的Windows 10，python 3.6.4 x64。 – Igor
