Python安装编译错误

Question

我希望有人可以帮助我,因为我已经坚持了一段时间,而且我对编译软件包不是很熟悉.尝试安装以下软件包:https://github.com/jhkorhonen/MOODS/wiki/Installation

运行Python 3.5(Anaconda),Windows 10 64位,Microsoft Visual Studio 2017社区版.这是我到目前为止所做的.

• 错误1:cd编辑提取的包位置,并运行python setup.py install --user但得到的错误说:

  running install running build running build_py running build_ext building 'MOODS._tools' extension cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -Icore/ -IC:\Users\Wolf\Anaconda3\include -IC:\Users\Wolf\Anaconda3\include /EHsc /Tpcore/tools_wrap.cxx /Fobuild\temp.win-amd64-3.5\Release\core/tools_wrap.obj -march=native -O3 -fPIC --std=c++11 error: command 'cl.exe' failed: No such file or directory

• 解决方案1:结果C:\Program Files (x86)\Microsoft Visual Studio 14.0没有\VC它正在寻找的文件夹,但我确实找到了C:\Program Files (x86)\Microsoft Visual Studio\Shared\14.0\VC\bin,所以我添加了PATH.

然后另一个错误:

• 错误2: C:\Program Files (x86)\Microsoft Visual Studio\Shared\14.0\VC\bin\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -Icore/ -IC:\Users\Wolf\Anaconda3\include -IC:\Users\Wolf\Anaconda3\include /EHsc /Tpcore/tools_wrap.cxx /Fobuild\temp.win-amd64-3.5\Release\core/tools_wrap.obj -march=native -O3 -fPIC --std=c++11 cl : Command line warning D9002 : ignoring unknown option '-march=native' cl : Command line warning D9002 : ignoring unknown option '-O3' cl : Command line warning D9002 : ignoring unknown option '-fPIC' cl : Command line warning D9002 : ignoring unknown option '--std=c++11' tools_wrap.cxx c:\users\wolf\anaconda3\include\pyconfig.h(68): fatal error C1083: Cannot open include file: 'io.h': No such file or directory error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\Shared\\14.0\\VC\\bin\\cl.exe' failed with exit status 2
• 解决方案2:所以我添加了一个环境变量INCLUDE并将其设置为C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\ucrt,具有io.h.

但是,又一个错误:

C:\Program Files (x86)\Microsoft Visual Studio\Shared\14.0\VC\bin\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -Icore/ -IC:\Users\Wolf\Anaconda3\include -IC:\Users\Wolf\Anaconda3\include "-IC:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\ucrt" /EHsc /Tpcore/tools_wrap.cxx /Fobuild\temp.win-amd64-3.5\Release\core/tools_wrap.obj -march=native -O3 -fPIC --std=c++11 cl : Command line warning D9002 : ignoring unknown option '-march=native' cl : Command line warning D9002 : ignoring unknown option '-O3' cl : Command line warning D9002 : ignoring unknown option '-fPIC' cl : Command line warning D9002 : ignoring unknown option '--std=c++11' tools_wrap.cxx C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\ucrt\corecrt.h(10): fatal error C1083: Cannot open include file: 'vcruntime.h': No such file or directory error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\Shared\\14.0\\VC\\bin\\cl.exe' failed with exit status 2

我不知道如何解决这个问题.似乎添加东西PATH并没有帮助很多.也许它与Universal CRT的推出有关？我应该卸载Visual Studio 2017并使用旧版本吗？

Answer 1

我在运行Python 3.5(Anaconda),Windows 10 64bit,Microsoft Visual Studio 2017专业版时遇到了类似的问题.

您是否尝试在命令行上启用64位Visual C++工具集？为此,vcvars64.bat请先在命令行上运行 .在我的情况下,本地化是:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build

这对我来说足够了,解决了我的问题.

另外,我看到一些用户必须安装"Windows Universal CRT SDK"(我已经有了).检查您是否也有:

1. 运行Visual Studio安装程序.
2. 选择修改按钮.
3. 转到"个别组件"选项卡.
4. 向下滚动到"编译器,构建工具和运行时".
5. 勾选"Windows Universal CRT SDK".
6. 安装.

PS:为方便起见,我建议使用powershell.vcvars64.bat从这里设置示例的脚本:

pushd "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build\"
cmd /c "vcvars64.bat&set" |
foreach {
  if ($_ -match "=") {
    $v = $_.split("="); set-item -force -path "ENV:\$($v[0])"  -value "$($v[1])"
  }
}
popd
