I'm currently using the Anaconda package with Python 2.7.9-1
Yesterday I upgraded the Spyder-app via the Anaconda Launcher and all of my scripts now crash. (Some bugs are already reported in the issues page https://github.com/spyder-ide/spyder/issues). How can I downgrade to the previous Spyder version meanwhile those bugs are fixed?
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 .
The requirements to run Spyder are: Python 2.7 or >=3.3. PyQt5 >=5.2 or PyQt4 >=4.6. 0 (PyQt5 is recommended).
In Anaconda Navigator, on Spyder tab, you have a settings symbol on top right corner. Press that and select 'Install specific version' option
You can install a specific version of spyder with conda. For instance, to install 2.3.5.2, run
conda install spyder-app=2.3.5.2
in the terminal.
