Windows + virtualenv + pip + NumPy（安装NumPy时出现的问题）

Question

提问by oob

On Windows, I normally just use the binary installer, but I would like to install NumPyonly in a virtualenv this time, so I created a virtual env:

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

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

Then I tried to install NumPy

然后我尝试安装 NumPy

pip install numpy

And I get an error. My pip.log is pasted below:

我得到一个错误。我的 pip.log 粘贴在下面：

I've had success installing NumPy binaries into a virtualenv with good 'ol easy_installand a little bit of un-archiving magic.

我已经成功地将 NumPy 二进制文件安装到虚拟环境中，easy_install并具有良好的 'ol和一些取消归档魔法。

The numpy-1.x.x-win32-superpack-python2.x.exerelease you download from SourceForgeis 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.

numpy-1.x.x-win32-superpack-python2.x.exe您从SourceForge下载的发行版实际上只是围绕三个单独的二进制发行版（启用SSE3、SSE2或不启用 SSE，具体取决于您的 CPU 的功能）的薄包装。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安装文件解压缩到某处以单独使用。

Then, activate your virtual environment, and run

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

to install the SSE3-optimized binaries, for example. easy_installis smart enough to find everything it needs inside that wininstbundle and will extract the compiled egginto 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.

例如，安装 SSE3 优化的二进制文件。easy_install足够聪明，可以在该wininst包中找到它需要的所有内容，并将编译后的蛋提取到您的 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 安装依赖于 NumPy 的其他软件包工作正常。

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 4or 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.

唯一的问题是知道要使用哪个优化级别（SSE3、SSE2 或 no-SSE）。如果您有一个相当现代的处理器（比Pentium 4或Athlon 64 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正常。

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.

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，但在提供官方版本时坚持使用官方版本通常更容易/更快/更安全。

Since pip can only install from source, you need to have the setup to build and compile NumPyto be able to use pip. I never tried this.

由于 pip 只能从源代码安装，因此您需要进行设置以构建和编译NumPy才能使用 pip。我从来没有试过这个。

What I did recently to get NumPy, SciPyand Matplotlibinto a virtual environment on Windows 7 is to copy the directories and eggfiles from my regular Python install directly into the virtual environment. For Matplotlib I also managed to unzip the binary installer directly into the virtualenv (I only tried this for the Gohlke installer for Python 3.2).

我最近为将 NumPy、SciPy和Matplotlib引入 Windows 7 上的虚拟环境所做的是将常规 Python 安装中的目录和egg文件直接复制到虚拟环境中。对于 Matplotlib，我还设法将二进制安装程序直接解压缩到 virtualenv 中（我只在 Python 3.2 的 Gohlke 安装程序中尝试过这个）。

I did manage in the past to easy_install NumPy into a virtualenv from a binary distribution, but I didn't manage this time (NumPy 1.5.1).

过去我确实设法将 NumPy 从二进制分发版轻松安装到 virtualenv 中，但这次我没有做到（NumPy 1.5.1）。

Someone recommended http://pypi.python.org/pypi/pygwhich should allow to install from binary packages to a virtualenv, but I haven't tried it yet.

有人推荐了http://pypi.python.org/pypi/pyg，它应该允许从二进制包安装到 virtualenv，但我还没有尝试过。

I didn't have to do the trick of unpacking the .exe file. I just activated my virtual environment, and then:

我不必解压 .exe 文件。我刚刚激活了我的虚拟环境，然后：
