Windows + virtualenv + pip + NumPy(安装NumPy时出现问题)

oob*_*oob 26 python windows numpy pip virtualenv

在Windows上,我通常只使用二进制安装程序,但是这次我只想在virtualenv中安装NumPy,所以我创建了一个虚拟环境:

virtualenv --no-site-packages --distribute summary_python
cd summary_python/Scripts
activate.bat

然后我尝试安装NumPy

pip install numpy

我收到一个错误.我的pip.log粘贴在下面:

我已经成功地将NumPy二进制文件安装到virtualenv中,具有良好的'ol easy_install和一点点归档魔法.

numpy-1.x.x-win32-superpack-python2.x.exe您从SourceForge下载的版本实际上只是一个围绕三个独立二进制发行版的薄包装(具有SSE3,SSE2或未启用SSE,具体取决于您的CPU的功能).如果在7-Zip(或其他存档实用程序)中打开superpack EXE文件,则可以在某处单独提取这些单独的安装文件.

然后,激活您的虚拟环境,然后运行

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,可以在该wininst捆绑包中找到所需的一切,并将已编译的鸡蛋提取到virtualenv的site-packages文件夹中.我还可以确认pip在执行此操作时仍能识别和/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).如果你有一个相当现代的处理器(比Pentium 4或Athlon 64更新),那么使用完整的SSE3可能是安全的.您也可以运行测试套件以确认一切按预期工作.

我发现easy_install"技巧"对于将各种二进制包安装到virtualenv非常有用.即使我在我的机器上安装了所有必需的编译器,但是当提供正式版本时,通常更容易/更快/更安全地使用正式版本.
