ResolvePackageNotFound of Readline and ncurses

[yongnuan]

I am using conda and wind10.

Retrieving notices: ...working... done
Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound:

• readline=8.2
• ncurses=6.4
  Then I tried to install readline and ncurses individually, then it said the following packages are not available from current channels.

conda install conda-forge::readline
conda install anaconda::ncurses

PackagesNotFoundError: The following packages are not available from current channels:

• anaconda::ncurses

pip install have much lower version of above 2 libary.

Thanks for help.

Hi @yongnuan! We had earlier discussions about this. The problem here is that WIndows doesn't have ncurses and readline (I am guessing you are on Windows?).

If you can use the Docker installation (or you use WSL) you should be fine. Otherwise, if you want to debug this issue, could you post the output for conda when you run without these two lines (ncurses and readline)?

@jlcanibe did you find a solution for this?

I am getting the same issue. After removing the two lines, the installation doesn't seem to stop and keeps on going endlessly.

@bdeva1975 that's annoying! I can't test this at the moment - I don't have Windows. Have you heard of WSL? It allows you to run Linux on Windows, and often makes it much easier to install software. Here's a link that explains the installation: https://learn.microsoft.com/en-us/windows/wsl/install?

Thanks a lot for your response. Currently my laptop has very limited resources. I know about WSL. I will use WSL as and when my resources are upgraded.

Hello @benman1 , I found the windows versions of these two packages:

• m2-ncurses
• pyreadline

I guess they could serve the same purpose, just rename them in the code and make sure they have the same syntax.
