No module named 'sympy'

Question

I am trying to import sympy and I get no module error. This is because I recently installed python 3.9 and when i search where sympy is stored it says python 3.8.6 how can I move the libraries to 3.9? Or can I downgrade idle? I am using ubuntu. Thanks!

Answer 1

Install pip for python3.9. You can do that using following commands

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python3.9 get-pip.py
python3.9 get-pip.py --user

Then you can use pip for installing sympy

In case if you want to take with the virtual environment path you can refer the above solution given by Anti_cse51, but you need to use python3.9 -m venv my-project-env for creating the virtualenv instead python3

Answer 2

Create a virtual environemnt

python3 -m venv my-project-env

Activate the envirnoment

source my-project-env/bin/activate

then install sympy

pip install sympy

This was there would be no conflict with local packages
