[snippsat]

I would like to work in standalone mode so no internet is connected it will be in private network. is this posiable? How do I down load the library and install in which directory? see below for the error.

You install with pip install junos-eznc,all is done automatically download and install.
It dos install many libraries,here a run with virtual environment.
You can drop virtual environment not required and just install.

C:\code
λ python -m venv junos_env

C:\code
λ cd junos_env\

C:\code\junos_env
λ C:\code\junos_env\Scripts\activate

(junos_env) C:\code\junos_env
λ pip install junos-eznc

So as you see it works.

You have one white-space to much.
And probably not install correct as ModuleNotFoundError.

Error:
>>>   from jnpr.junos import Device # One white-space 
  File "<stdin>", line 1
    from jnpr.junos import Device
    ^
IndentationError: unexpected indent

>>> ModuleNotFoundError: No module named 'jnpr'
