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

逑禄
2023-03-14
问题内容：

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，因此我创建了一个虚拟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：

问题答案：

我已经成功地将NumPy二进制文件安装到具有良好的’oleasy_install和一点未归档魔术的虚拟环境中。

numpy-1.x.x-win32-superpack- python2.x.exe您从SourceForge下载的发行版实际上只是三个独立的二进制发行版的薄包装（根据您的CPU功能，启用SSE3，SSE2或不启用SSE）。如果您在7-Zip（或另一个存档实用程序）中打开superpack
EXE文件，则可以将这些单独的安装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，安装经过SSE3优化的二进制文件。easy_install非常聪明，可以在wininst捆绑包中找到它所需的一切，并将已编译的egg提取到您的virtualenv的site-
packages文件夹中。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安装其他依赖于NumPy的软件包也可以。

唯一的困难是知道要使用哪个优化级别（SSE3，SSE2或否-
SSE）。如果您有一个相当现代的处理器（比奔腾4或Athlon
64更新），那么使用完整的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，但提供官方版本时，通常更容易/更快/更安全。
