Why can't I use the libraries in Spyder 4?

I downloaded Anaconda, and launched Spyder 3.something. I created a program that included sympy in it and ran it with no problems. When I re-opened Spyder later, I got a pop-up saying that Spyder Version 4.0.1 was available. I then went to update it. Once updated I tried to run the same code and it gave me an error: ModuleNotFoundError: No module named 'sympy'. What do I need to do so that all the libraries in Anaconda are use-able again in Spyder. I'm pretty new to Python.

Note: I did not do any initial setup to have sympy, numpy, etc. in Spyder 3.something, they were automatically implemented. Thanks!

The IDE doesn't manage the libraries. Anaconda / Pip do – OneCricketeer Feb 08 '20 at 02:16

I think you should be able to launch Spyder from the specific environment you want. – AMC Feb 08 '20 at 02:30
activate the env in anaconda prompt and launch spyder from that env by running `spyder`...try that – Derek Eden Feb 08 '20 at 03:57
