pip not installing modules

As per object. I'm running Python 2.7.10 under Windows 7 64 bit. I added C:\Python27\Scripts to my PATH, and I can run pip, but it's not able to install modules. For example

pip install numpy

gives

Collecting numpy
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after
connection broken by 'ProtocolError('Connection aborted.', gaierror(11004,'getaddrinfo failed'))': /simple/numpy/

It keeps retrying and failing for a while, and then it exits with

Could not find a version that satisfies the requirement numpy (from versions:
)
No matching distribution found for numpy

Probably I'm behind a firewall, but I'm quite disappointed because I can install packages under R perfectly fine with install.packages, and I don't see why I can't do the same with Python. If I install packages manually (in the case of NumPy, from here

NumPy

what do I miss, with respect to using pip?

As per suggestions in the comments, I downloaded the .whl file for NumPy from NumPy. I navigated to the downloads dir and executed

pip install numpy-1.10.1-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl

I only got

numpy-1.10.1-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl is not a supported wheel on this platform.

What should I do?

Our company laptops were too locked down (with scripts and pac files in proxy settings, i.e. blackspider settings), and only the following worked for me.

To solve, I used the following simple steps:

  • Go directly to pypi.org.
  • Search for the library: python-dateutil
  • Download it
  • (Optional) Switch to the correct conda environment
  • Install:
pip install "C:\Users\joe\Downloads\python_dateutil-2.8.2-py2.py3-none-any.whl"

You could try this one as well! Setting pip configuration using a proxy so that you do not need to concern the proxy issue again when you install packages via pip.

pip config set global.proxy http://restrictedproxy.xxx.com:70

http://restrictedproxy.xxx.com 
:70

you could probably ask the proxy domain and the port from IT if you work for a company.

Personally, it was the configuration file in ~/.config/pip/pip.conf, which contained an extra-index-url, preventing the download, because it made pip search for all the packages on this extra url instead of the main pip repository.

I experimented with old pip 8, because upgrading was even worse for this extra-index-url needed for another project.

If you use Anaconda:

I was trying to install Django using cmd, and it just was not working! I opened up the Anaconda prompt and ran the usual

py -m pip install Django

command, and hey presto! Django was installed!

To bypass the firewall, you can use a proxy

pip install numpy --proxy <domain\user:password@proxyaddress:port>

For example,

pip install numpy --proxy http://<username>:<password>@proxy.xyz.com:2180

A proxy shall be used. For example:

python.exe -m pip install numpy --proxy="proxy.com:8080"

where "proxy.com:8080" is the proxy server address and port. This can be found in OS settings.

How to get them:

  1. Windows: What Is a Proxy or Proxy Server
  2. Linux How can I find out the proxy address I am behind?
  3. Mac OS X: How can I get Mac OS X's proxy information in a Bash script?
