[FIXED] Spyder 4.01 and plotly 4.5.1 - Anaconda attempts downgrade of Spyder

Issue

i am attempting to install plotly 4.5.1 using the anaconda environment - conda install -c plotly plotly.

However i can see from the terminal that Anaconda attempts to downgrade Spyder back to v 3.3.6. See attached picture:

I would like to carry on using Spyder v4.0.1 but also need plotly. What is the best way to deal with this? I guess different anaconda environments, but then would that mean working in Spyder 3.3.6 to do my plotting?

PS: I also plan to install plotly-dash for dash board development. I suspect that this may also run into the same issue.

Thanks for the help in advance.

Solution

(Spyder maintainer here) We're trying to solve this problem with the Anaconda people right now. Hopefully it'll be fixed in the next days. In the meantime, please see this issue for possible solutions.
