Numpy Does Not Install

Question

I’m basically trying to install Pandas, but to do that I’m supposedly supposed to be installing Numpy.

I type this into the terminal:

pip install numpy

And I get an error which basically says I need Microsoft Visual Studio C++ 14.0. After I downloaded it from the link it provided, I have absolutely no idea how to work with it. I’ve tried to use a YouTube tutorial on how to use Visual Studio, but when they create a project I don’t have any of their options. The only option I have is to create a blank solution.

If the rest of the error message is necessary please alert me of that, I’ve only started to work with Python for a couple months, so I’m not very experienced.

Error Message:

Answer 1

Got a couple options:

1) Download the Binary from Unofficial Windows Binaries for Python Extension Packages

For projects which don’t provide their own Windows installers (and even some which do), Christoph Gohlke at the University of California provides a collection of Windows installers. Many Python users on Windows have reported a positive experience with these prebuilt versions. Source

https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

Search for and download:

numpy‑1.18.2+mkl‑cp38‑cp38‑win_amd64.whl

Open terminal, activate your env, and install (change the path to where file downloaded):

pip install C:\Users\pc\downloads\numpy‑1.18.2+mkl‑cp38‑cp38‑win_amd64.whl

2) Since you are using Windows (like I do), I would highly recommend taking advantage of Anaconda distribution of Python. Will save you a lot of time in the long run. Basically, it install the binary packages rather than requiring you to compile resources using pip.

Since you are using Pycharm, after you install Anaconda, go back to Pycharm, create a new environment using Conda and then pip install numpy.

3) Try to Compile (Good Luck)
