I run Linux Mint 20.2 and have EinsteinPy installed in the local directory which I used to use when running programs from the Terminal.

Recently, when I tried to use the anaconda IDE to do programming and tried installing the package from the base terminal of Conda, I failed!

I used,

(base) manu@KillingMachine:~$ conda install einsteinpy

and the results are as follows:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

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

  - einsteinpy

Current channels:

  - https://repo.anaconda.com/pkgs/main/linux-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/linux-64
  - https://repo.anaconda.com/pkgs/r/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.
