在 Windows 上，我通常只使用二进制安装程序，但我想安装 NumPy这次只在virtualenv中，所以我创建了一个virtual env:
virtualenv --no-site-packages --distribute summary_python
cd summary_python/Scripts
activate.bat
然后我尝试安装 NumPy
pip install numpy
我得到一个错误。我的 pip.log 粘贴在下面:

最佳答案
我已经成功地将 NumPy 二进制文件安装到一个具有良好 'ol easy_install 和一 pip 解档魔法的虚拟环境中。
您从 SourceForge 下载的 numpy-1.x.x-win32-superpack-python2.x.exe 版本实际上只是围绕三个单独的二进制发行版的薄包装器(有 SSE3 、 SSE2 或未启用 SSE，具体取决于 CPU 的功能)。如果你打开 7-Zip 中的 superpack EXE 文件(或其他存档实用程序)，您可以将这些单独的设置文件提取到某个地方以单独使用。
然后，激活您的虚拟环境并运行
easy_install c:\path\to\extracted\numpy-1.x.x-sse3.exe
例如，安装 SSE3 优化的二进制文件。 easy_install 足够聪明，可以在 wininst 包中找到它需要的所有内容，并将提取已编译的 egg进入你的 virtualenv 的 site-packages 文件夹。我还可以确认，当您执行此操作时，pip 仍然能够识别和/或卸载 NumPy，并且使用 pip 安装依赖于 NumPy 的其他软件包也可以正常工作。
唯一的问题是知道要使用哪个优化级别(SSE3、SSE2 或无 SSE)。如果您有 reasonably modern processor (比 Pentium 4 或 Athlon 64 更新)，使用完整的 SSE3 可能是安全的。您可能还可以运行测试套件以确认一切正常。
我发现 easy_install “技巧”对于将各种二进制包安装到 virtualenv 中非常有用。尽管我在我的机器上设置了所有必需的编译器，但如果提供了官方版本，通常更容易/更快/更安全。
