问题描述
在Windows上，我通常只使用二进制安装程序，但是我想安装 NumPy 这次只在virtualenv中，所以我创建了一个虚拟env:
On Windows, I normally just use the binary installer, but I would like to install NumPy only in a virtualenv this time, so I created a virtual env:
virtualenv --no-site-packages --distribute summary_python
cd summary_python/Scripts
activate.bat
然后我尝试安装NumPy
Then I tried to install NumPy
pip install numpy
我得到一个错误.我的pip.log粘贴在下面:
And I get an error. My pip.log is pasted below:

推荐答案
我已经成功地将NumPy二进制文件安装到具有良好的'ol easy_install和一点未归档魔术的虚拟环境中.
I've had success installing NumPy binaries into a virtualenv with good 'ol easy_install and a little bit of un-archiving magic.
您从 SourceForge 下载的numpy-1.x.x-win32-superpack-python2.x.exe版本实际上只是三层薄包装单独的二进制发行版(带有 SSE3 ， SSE2 ，或未启用SSE，具体取决于您的CPU的功能).如果您在 7-Zip (或其他存档实用程序)中打开superpack EXE文件，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.
The numpy-1.x.x-win32-superpack-python2.x.exe release you download from SourceForge is really just a thin wrapper around three separate binary distributions (with SSE3, SSE2, or no SSE enabled, depending on the capabilities of your CPU). If you open up the superpack EXE file in 7-Zip (or another archive utility), you can extract those individual setup files somewhere to use separately.
然后，激活您的虚拟环境并运行
Then, activate your virtual environment, and run
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捆绑包中找到所需的一切，并将提取的鸡蛋提取到您的virtualenv网站中-包文件夹.我还可以确认，当您执行此操作时，pip仍可以识别和/或卸载NumPy，并且使用pip安装其他依赖于NumPy的软件包也可以.
to install the SSE3-optimized binaries, for example. easy_install is smart enough to find everything it needs inside that wininst bundle and will extract the compiled egg into your virtualenv's site-packages folder. I can also confirm that pip is still able to recognize and/or uninstall NumPy when you do this, and that using pip to install other packages which depend on NumPy works just fine.
唯一的困难是知道要使用哪个优化级别(SSE3，SSE2或no-SSE).如果您有合理的现代处理器(比奔腾4 或 Athlon 64 )，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.
The only catch is knowing which optimization level to use (SSE3, SSE2, or no-SSE). If you have a reasonably modern processor (newer than, say, a Pentium 4 or Athlon 64), it's probably safe to go with the full SSE3. You can probably also run the test suite to confirm everything works as expected.
我发现easy_install技巧"对于将各种二进制程序包安装到virtualenv中非常有用.即使我的机器上已经安装了所有必需的编译器，但提供了正式版本后，通常更容易/更快/更安全地坚持使用官方版本.
I've found the easy_install "trick" to be really useful for installing all sorts of binary packages into a virtualenv. Even though I have all the requisite compilers set up on my machine, it's usually easier/faster/safer to stick with the official release when one is provided.
