I installed python 3.9 on my computer. When I try to install jupyter notebook I got this error. SO how to solve this issue ?

Answer 1

I had the exact same issue as you. This is how I solved it.

I found the answer here: https://discuss.codecademy.com/t/having-trouble-installing-jupyter-notebooks/537292/2

You can use the link and follow the instructions if you'd like. I'll also tell you how to do it here.

It's an easy fix. The error is about the Microsoft Visual C++ being out of date. In the error it gives you the link for the update.

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

Go to https://visualstudio.microsoft.com/visual-cpp-build-tools/ and click 'Download Build Tools' and install it.

Once it's installed, you'll see a few choices. Select 'C++ build tools' and install it. Restart your computer after it's done. Then run pip install jupyter and you should be good!
