Installing extension modules can be an issue with pip. This is why conda exists. conda is an open-source BSD-licensed cross-platform package manager. It can easily install NumPy.

Two options:

• Install Anaconda (http://www.continuum.io/downloads)
• Install Miniconda (http://repo.continuum.io/miniconda/index.html) and then go to a command-line and type conda install numpy (make sure your PATH includes the location conda was installed to).

I would guess this is due to pip 1.3 has a bug dealing with ssl. There is a link here.

回答3:

Some File can not be installed with pip and need to be installed from your platform’s packages.

So You guys can try this if nth work up there MAC With Macports

sudo port install 'package' 

With Homebrew:

brew install 'Package'

Make sure you have python-dev installed (as you'll definitely see this same error if you don't).

dpkg -l python-dev

回答5:

I downloaded python 37, and I customized install location. Then I tried to install numpy using pip: failed error code 1. Then I deleted python 37, downloaded python 36 without customizing install location. Then I installed numpy using pip: successful. Perhaps customizing install location caused the error.
