title: Installing numpy with pip on windows 10 for python 3.7
body: <p>I installed python 3.7 on my Windows 10 laptop since it has been officially released as of today (06/28/2018). Then i tried to install numpy package using pip </p>
  
  <pre><code>pip install numpy
  </code></pre>
  
  <p>The install proceeds but finally fails with the below error :</p>
  
  <pre><code>        source = func(extension, build_dir)
        File "numpy\core\setup.py", line 675, in get_mathlib_info
          raise RuntimeError("Broken toolchain: cannot link a simple C program")
      RuntimeError: Broken toolchain: cannot link a simple C program
