When I run my code with Sympy it works fine but when I now go live I get the error sympy package is not found. I have checked and found the package is installed and whenever I try to uninstall it so that I can install it back and see if tit works, I get the error message: OSError: [Errno 13] Permission denied: '/usr/bin/isympy' Other packages like numpy are not showing any errors what can I do to resolve this issue with sympy

You will be not able to remove system wide pre-installed packages. Make sure that the code you run that is showing the error uses the same Python environment that you used for testing. Otherwise (for example if you use a virtual environment) you may need to install the required package for this environment separately.

I see that your website is set up to use a virtualenv. Have you specifically installed sympy into that virtualenv? When you run code from the editor, it won't be using it -- it will just use the default system environment, which has a lot of packages installed. To install it into the virtualenv, start a Bash console in the env using the link on the "Web" page, and run "pip install sympy".

Could you go to your the Web page, click on the link below the virtualenv path ("Start a console in this virtualenv") and run pip show sympy? If it's not installed, then -- still being in that very console -- run pip install sympy and check if that installs correctly.

@giles I have done as you say but nothing. Are you guys able to view the images I have attached. Correct me if I'm wrong but have I not used the link to my webpage
