How to upgrade a package in Mathematica?

If I have a package installed,开发者_高级运维 that has built-in documentation, and I want to install an updated version of the same package, is it safe just to erase the old version folder?

Last time I tried, I got some error messages on the documentation, but never understood if the problem came from this fact. Is there an “uninstall package” procedure?

Thank you, Pedro

If the package has an installer, you should see if it has a corresponding uninstall mode. Otherwise, simple deletion should be safe.

If you do run into any errors, feel free to update your question.
