Installing numpy with pip on windows 10 for python 3.7

Question

I have installed python 3.7 on my Windows 10 os. Then I tried to install the numpy package using the pip command:

pip install numpy

I am getting the below error :

        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")

Answer 1

First, try to install pipwin from PyPI:

pip install pipwin

When that's installed, you can then do:

pipwin install numpy

In this way, you will install the latest version of NumPy on your system. 

For more information regarding the same, do refer to the Python certification course.
