使用Python 2.7在64位Windows 8.1上安装Numpy

Question

I am trying to install Numpy on Python 2.7 and I am using Windows 8.1. When I run Numpy from this link it says, "Python 2.7 required, which was not found in the registry ". How can resolve this issue, I already installed Python 2.7?

Answer 1

For Windows, you should check out Chris Gohlke's page: http://www.lfd.uci.edu/~gohlke/pythonlibs

He has some Numpy builds there for Python 2.7.

Answer 2

You can first install wheel using pip.

pip install wheel

Then download the .whl file for Numpy from Chris Gohlke's page .

Then go to the directory where you downloaded the package.whl file in cmd and do the following

pip install package_you_downloaded.whl

I experienced a similar broken toolchain error while installing Numpy. You can check it here .

Answer 3

I changed to anaconda a while ago and in my mind its the best and most dynamic package manager for all platforms. http://docs.continuum.io/anaconda/install.html

Answer 4

安装pip之后的正确命令是：

python -m pip install numpy
