This is driving me nuts. I'm brand new to python and just want to be able to import numpy but have failed while trying to follow 20 different sets of instructions. I know very little about installing things from command prompts, so please don't assume any knowledge.

So far I have installed pip and gotten that to seemingly work ok. When running "pip install numpy" from the cmd prompt it seemed to download OK but have a ton of error messages, ending with "Command python setup.py egg_info failed with error code 1 in c:\users\zak\appdata\local\temp\pip_build_Zak\numpy". I hadn't installed a compiler or anything and read that may be the issue. I installed mingw and selected most of the packages. I also added the mingw\bin to my path variable. Still nothing.

I THEN tried getting miniconda and using "conda install numpy python=3" because I read somewhere that that would work. That seems to install successfully but then all the files are in some "miniconda" directory and when I try the "import numpy" command from my IDLE3 interpreter, it still says no module named numpy.

So what is next? And why on earth is it so difficult to install and import a module? One fact that may be complicating things: I have my harddrive partitioned and I'm installing everything python related on drive G. My path variable is updated to include the relevant G:\ directories. My install log from pip:

从以下网址下载预构建的二进制文件可能更容易：http ://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

如果您的 python 安装是 32 位，那么您正在寻找numpy-MKL-1.8.0.win32-py3.3.exe. 对于 64 位 python numpy-MKL-1.8.0.win-amd64-py3.3.exe：.

或者您可以安装Anacondapython 发行版，其中包括所有常见的科学软件包：http ://continuum.io/downloads和 Ctrl+F 用于“Windows 安装程序”。

SciPy 文档中也有详尽的教程：

I had the same horrible experience installing and spent over 8 hours trying to get a fix and finally got it solved.

Installing extension modules e.g. NumPy can be an issue with pip. In most cases the best way to install NumPy on your system is by using an installable binary package for your operating system and Python version from the NumPy from Sourceforge download site

For your Python 3.3. on Windos 7 (64 bits), the installation steps are:

1) download numpy installer: numpy-1.8.1-win32-superpack-python3.3.exe (9.7 MB) for windows

2) run the .exe file and numpy will be installed into the C:\Python27\Lib\site-packages(where all packages installed using 'pip install package_name' or 'python setup.py install' commands are stored)

3) In your home directory on the command prompt, type 'pip list' command to view installed packages, and you will see the numpy version you just installed (this step will only work if you have installed Python and pip package as well as added the directories for both installations to your PATH in environment variables)

似乎 Python 3.5 和 numpy 1.9.3 pip install 终于可以工作了。

我有 Win7（64 位）/Python 3.5（32 位）/Visual Studio 2015 Express：

  • 打开 VS CMD 工具
  • 运行 pip install numpy

为了在不影响现有 Anaconda 配置的情况下安装额外的 Python 包，我认为，现在我们可以pip在 IDLE 中使用，不像友好的那样pip install numpy，而是在两个提示符下依次：

import pip
pip.main(["install","numpy"])

但是，请注意：安装过程并不漂亮，而且速度很慢。同样，如果您必须安装 SciPy，只需在上面的代码中numpy替换为。scipy
