Joe,

Thank you. That was exactly the issue. The correct command is just 'python.'

Hi,

...

I am trying to install Kwant on my Windows-8 system. (I am new to this. I have never used Python.) I tried to follow the instructions on the web page http://kwant-project.org/install#microsoft-windows. The final step in the installation is the following command:

python3 -c "import pip, glob; pip.main(['install', '--no-deps'] + glob.glob('*.whl'))"

When I try to execute this, I get a message that says ‘python3’ is not recognizable as a command. Can anyone tell me what I've done wrong?

Thanks.

My guess would be that Python has not been added to the system path correctly, or that it is not named `python3`. A bit of googling around ( https://docs.python.org/3/using/windows.html#from-the-command-line) seems to indicate that the program used to launch Python in Windows may be called something else. Can you try running

py -3 -c "import pip, glob; pip.main(['install', '--no-deps'] +

glob.glob('*.whl'))"

instead?

(hopefully) Happy Kwanting,

Joe

Christoph, Aside from the command name (it's 'python' instead of 'python3') everything seems to have gone well. I have not used it yet. I am a complete novice, so I will need time to go through some tutorials. -Joe

So you can confirm that the installation instructions for Windows are correct (up to the naming issue)? Any other observations?
