I'm trying to download the dependencies of paramiko from a linux host to a windows target which has no internet access .
After reading the example on pip's documentation I've used to following command in order to download the dependencies recursively to a 64 bit windows platform:
pip3 download --only-binary=:all: --platform win_amd64 --implementation cp paramiko
Was able to recursively download the dependencies until reaching pycparser. That is not surprising since I've used the --only-binary=:all: flag. Thing is - pip forces the usage of this flag when --platform flag is passed:
ERROR: --only-binary=:all: must be set and --no-binary must not be set (or must be set to :none:) when restricting platform and interpreter constraints using --python-version, --platform, --abi, or --implementation.
Terminal produced the following output:

Is there a way of overcoming this issue? Will I have to manually install non-binary packages (and their dependencies)?
Thanks, Joey.

The pip download command can be used to download packages and their dependencies to the current directory (by default), or else to a specified location without installing them.
Pip will not flag dependency conflicts. As a result, it will happily install multiple versions of a dependency into your project, which will likely result in errors. One way to avoid dependency conflicts is to use an alternative Python package manager, like conda, poetry or ActiveState's State Tool.
Overview. pip download does the same resolution and downloading as pip install , but instead of installing the dependencies, it collects the downloaded distributions into the directory provided (defaulting to the current directory).
You have two options:
Don't try other fancy method or you will shut yourself in the foot: some dependencies will need to compile!
