Updating Spyder
If you installed Spyder through Anaconda (recommended), WinPython, MacPorts, or your system package manager, update using those same methods.
With Anaconda, just run (in Anaconda Prompt if on Windows) conda update anaconda to update the distribution as a whole and conda update spyder to update Spyder specifically.
If you installed Spyder via the advanced/cross-platform method, pip, run pip install --upgrade spyder. This command will also update all Spyder dependencies, so we recommend you use an isolated virtualenv or venv environment to avoid any potential unintended effects on other installed packages.
