Question

How to check the current version of SymPy and upgrade to the latest version?

I am using macOS. The way I installed my current version is using pip install sympy.

Answer 1

To check the current version of sympy:

In [6]: import sympy  In [7]: sympy.__version__ Out[7]: '0.7.6-git' 

For stable release:

$ pip install --upgrade sympy 

For latest features:

$ pip install --upgrade git+ssh://[email protected]/sympy/sympy.git 

Answer 2

Use pip list to list all packages and their versions. You can pipe it to grep to search for the package your interested in:

pip list | grep sympy

Alternatively to get all information about that package including version you can use pip show:

pip show sympy

To upgrade it's simply:

pip install --upgrade sympy

If you need write permissions to your python installation directory don't forget to prepend the pip install command with a sudo: e.g. sudo pip install --upgrade sympy
