Help of Installation failure

Hello, I want to install fermitools with conda using : conda install fermitools / conda install -c conda-forge fermitools But they both failed with an error:

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

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

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

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

So does anyone can help with solving this problem?

I tried 'conda config --append channels conda-forge' or 'conda config --set restore_free_channel true ' but still not work. Anyone know how to fix that? Thank you very much!

And I try to search it with 'conda search -f fermi' But the result just have packages: fermipy 1.0.1 py39hef51801_1 conda-forge
forestopenfermion 0.0.6 pyhd8ed1ab_1 conda-forge
ifermi 0.3.0 pyhd8ed1ab_0 conda-forge
openfermion 1.5.1 pyhd8ed1ab_0 conda-forge
openfermionpsi4 0.5 pyhd8ed1ab_0 conda-forge
openfermionpyscf 0.5 pyhd8ed1ab_0 conda-forge
r-fermicatsr 1.4 r42h142f84f_0 pkgs/r There is not femitools. So, is there any wrong with my searching?

Installation instructions are available on the Fermitools wiki.

[PepeJoseHU]

Dear donhorner,

Do you have any suggestions? I tried with ' conda install -c fermi fermitools=2.2.0' ' conda install -c fermi fermitools=2.1.0' ' conda install -c fermi fermitools=2.0.0' both failed. I have no idea how to install fermitools in my enviroment.

Thanks!

[donhorner]

Have you tried the install command given in the documentation? You should be creating a separate environment for the Fermitools.

[PepeJoseHU]

Dear donhorner,

I want to install it in an exist environment, is that possible? Or if there have ways for that? That is the reason I used a specified version of fermitools

Thanks!

[PepeJoseHU]

THANKS， i give up. A new environment is built and it installed already with python 3.9. Thanks again.

If you want to keep the environment name next time, it is best to probably best to remove the environment first with 'conda env remove -n ENV_NAME' and redo the installation using the same name.

[PepeJoseHU]

@nmirabal, Not keep the name, just keep these settings in the environment. If just a name, I can make a new environment with the same name.
