OSError: Unsupported platform 'CYGWIN_NT-10.0-19044'

[Jose Isaias Cabrera]

Greetings.

Python 3 apparently does not support the python keyboard library in Cygwin:

$ python3
Python 3.9.10 (main, Jan 20 2022, 21:37:52)
[GCC 11.2.0] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import keyboard
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/keyboard/__init__.py", line 128, in <module>
    raise OSError("Unsupported platform '{}'".format(_platform.system()))
OSError: Unsupported platform 'CYGWIN_NT-10.0-19044'
>>>

Any ideas on how I can make this work?  Thanks.

First thing to find out if it's truly broken, or just not known to
work.

With a _safe_ test case, just try editting the code to allow Cygwin,
e.g. on line 121 of keyboard/__init__.py:

  if _platform.system() in ['Windows','CYGWIN_NT-10.0-19044']:

If that doesn't work, try a similar edit on line 123.

One way or the other, you should find out what the _real_ problem is.

Let's see how far I can go. All I want is to capture the ENTER key in a website powered by python3. Thanks for the ideas.

Two things to try:
 1) Run python from an elevated shell (unlikely to make a difference);
 2) Same strategy -- edit _nixcommon.py to always return true from
    ensure_root.

Good luck,

This was the easy part. :-) Same issue.

Now, it's getting a little deeper, but I will try this again tomorrow.

$ cat chkKBoard.py
#!/usr/bin/python3

while True:
    if keyboard.is_pressed("a"):
        print("You pressed 'a'.")
        break

This is tomorrow's problem. Can't work tomorrow's problem today. :-) Thanks for the ideas.

If you will be running X (and Cygwin supports, but does not require that),
then the xorg backend (meaning: not the Windows one) with pynput (note, that
package has no "i" in its name) may achieve your goal.

it is your own build

I assume you are installing

    https://pypi.org/project/keyboard/

and it seems requires dedicated HDW interfaces
   "Works with Windows and Linux (requires sudo), with experimental OS X 
  support"


So you are on your own

Well, this is not part of Cygwin Setup python3's library. So, I installed it using pip3:

$ ls *.whl
keyboard-0.13.5-py3-none-any.whl*

$ pip3 install keyboard-0.13.5-py3-none-any.whl

Yes.

It says it works with Windows, why am I on my own?  It should work.

Because you're not on Windows. You're on Cygwin, which acts as a POSIX
(Unix-like) system.

If you want Python *on Windows*, start here:

Wow! Thanks for that deep thought. :-) I knew that. :-) I have been using Cygwin since 1999 (sometimes more than others). I just thought that by now, Windows would have started playing nicer and had made enough changes to be friendlier to POSIX. Long story, but I need to use Cygwin for this. Thanks, though.

Sorry - hard to know whether one is dealing with a "newbie" or not.

In Thunderbird, I sort by "Correspondents" and see he has been posting since at 
least 2019, you can also search "From, To, Cc, Bcc" or similar for the surname, 
and on the web e.g.

	https://inbox.sourceware.org/cygwin/?q=Cabrera&o=-1

shows 1998 - earlier than even he remembers ;^>

Post a bug that given the script runs in python, it works and is supported!
You may want to mention that uname -m (ARCH) and -o (Cygwin) are the safe 
options, -p and -i are optional, and uname -s may contain unexpected qualifiers 
(like Windows version and patch).
Perhaps on Cygwin platform.system() should return uname -o instead of -s?

If you want to try and fix it you could have it use a regex or a different 
method and make it work like some generic POSIX API platform:

Well, my apologies. I knew I was close. And I even thought to put 1998, but when I went to my email, I only found some for 1999. And because I like facts, thus, 1999. :-)
