Error install spyder

[xjugs]

when I try install spyder from anaconda-navigator within radioconda environment, I got an error: "Spyder cannot be installed on this environment".

However, in other enviroments, I do success to install spyder. the problem exist just within radioconda environment.

I am using: ubuntu 20.04 radioconda 2023.02.24 (the latest one)

What happens if you try to install it from the command line, e.g. mamba install spyder from a terminal with the radioconda environment activated? If there's a package conflict, that should tell us.

I tried install spyder with conda: conda install spyder=5.4.2

there are indeed conflicts. I got:

---

why are there conflicts? I do have indeed another spyder on the base environment. Cann't I install the same package in another environment? I was able to install spyder to another environment other than the base or radioconda.

I don't know why there's a conflict, and what it claims is a conflict doesn't make sense to me (spyder needs ipython which needs linux, but it says you have linux in the line above that?). I'm able to install spyder in my radioconda environment without issues. Can you try installing it with mamba instead of conda? The different solver might give a better message. You'd need to have mamba installed in your base environment to use it.

[xjugs]

It indeed worked with mamba. But why? How is it differ from conda?

[ryanvolz]

Generally they should be the same, so I don't know why it's different here. Unless you could somehow coax a more informative error message out of conda, we probably won't ever find out.

Ok. Thank you
