Cannot Install Spacy on Windows 10 for Python 3.8

So… I have installed a Python 3.8.2 and put in “pip install -U spacy” to CMD; and then, things go wrong, and repeated attempts still didn’t render any success.

My Environment

• Operating System: Windows 10
• Python Version Used: Python 3.8.2 + Pip 20.1
• spaCy Version Used: Newest(2.2.4)
• Environment Information:

I have tried items recommended in the Troubleshooting section that I can match, but to no success; the spacy library is not installed. Below is the error messages:

I think it would good to go through the documentation of virtual environments that I linked earlier, to understand what they are about and how they work. It is useful to install any Python software - not just spaCy. The commands are slightly different on Windows and Linux.

On my Windows, the commands look something like this:

python -m venv myvenv
.\myvenv\Scripts\activate
pip install spacy --no-cache-dir

I found a working method to install spacy in anaconda (using anaconda prompt) create a virtual env in anaconda Then run the command conda install -c conda-forge spacy

I am using Python 3.8 and windown 32 bit machine
