Trouble installing a python package with conda

I'm trying to install a Python package (Pyclone) using anaconda (the latest release of miniconda, specifically) using the following suggested script:

conda install pyclone -c aroth85

And I get the following error:

Package missing in current win-64 channels

I'm not sure what exactly this means; Is it that the package is not being maintained?

I should note that when I tried putting the -c after install:

conda install -c pyclone aroth85

Because I saw that order used for other package, I got the following warning as well:

WARNING: The remote server could not find the noarch directory for the requested channel with url: https://conda.anaconda.org/pyclone It is possible you have given conda an invalid channel. Please double-check your conda configuration using conda config --show. If the requested url is in fact a valid conda channel, please request that the channel administrator create noarch/repodata.json and associated noarch/repodata.json.bz2 files, even if noarch/repodata.json is empty.
$ mkdir noarch
$ echo '{}' > noarch/repodata.json
$ bzip2 -k noarch/repodata.json

In addition to the original error about the package missing in current win-64 channels.

Does anyone know what the problem is here? Or do I need to contact package's maintainers if it's something wrong on their end?

By the way, the package's creators' installation instructions are here

Thanks.

You can see here that there is not a version of that package available for win-64, only linux-64 and osx-64: https://anaconda.org/search?q=pyclone

This means that the owner of the aroth85 channel does not maintain a package for Windows 64 bit. So, you'll have to go for the manual installation, which may or may not be a difficult task. The instructions are here: https://bitbucket.org/aroth85/pyclone/wiki/Installation#markdown-header-manual-installation According to the Tutorial, the author of the package has no intention of supporting Windows:

It almost certainly will not work for Windows and there will likely never be support in PyClone for Windows

Finally, regarding that warning - the -c or --channel option adds a channel for conda to search for the package. The name of the channel is the word that appears immediately after the flag, regardless of where the flag is located. Thus, the first command

conda install pyclone -c aroth85

looks in the aroth85 channel for a package called pyclone (and can't find the package, because it doesn't exist, as we saw at the link to anaconda.org). This command is equivalent to

conda install -c aroth85 pyclone

The second command

conda install -c pyclone aroth85

looks in the pyclone channel for a package called aroth85. The warning message means that conda cannot find a channel called pyclone, because no such channel exists. Then (I would guess) the error message states that conda cannot find a package called aroth85, again, because no such package exists.

I'm presuming you're using Windows, based on that error message. It looks like there isn't a Windows version of that package in the conda win-64 channels. This is something you could possibly try and raise with the package author, but if you just want to get the package working, I would suggest you try a manual install.

The details for doing a manual install are all given in the install instructions you linked to.
