when doing this 

conda install c anaconda idna=2.2

I have this and conda cannot find :

Fetching package metadata .........
Solving package specifications: .

    PackageNotFoundError: Package not found:
 '' Package missing in current win-64 channels:
      - c

However, you can see this in Win64 channels... https://anaconda.org/anaconda/idna/files

It's probably clear after Vladimir's comment but you can just do conda install idna=2.2. The packages in the anaconda channel are in the default channel so you don't need to use the channel name. If you want to specify the channel name then you can use -c or --channel like conda install -c anaconda idna=2.2.
