Unfortunately, the Conch standard-IO library (and therefore the conch terminal client, and twisted.conch.stdio) doesn't work on Windows and never has: https://twistedmatrix.com/trac/ticket/2157 <https://twistedmatrix.com/trac/ticket/2157>. However, you may be able to get it up and running with the Windows Subsystem for Linux, which I believe will present a Linux-like interface since as far as the application knows it's running on Linux: https://docs.microsoft.com/en-us/windows/wsl/about <https://docs.microsoft.com/en-us/windows/wsl/about> > I'm hoping that this will solve the rest of the error messages I'm having.

Or, for that matter, could you just write a little program? A sample Python script that runs the reactor is probably easier to set up than a reactor-enabled REPL, particularly on Windows. (There are various options for a reactor-enabled REPL, it's definitely doable, but it might be a bit rough as a first step; as you're discovering.) > The aim is to get the deferred responses as shown in previous code, but all I > get is: > > >>> from twisted.names import client > >>> client.getHostByName('www.example.com <http://www.example.com/>') > <Deferred at 0x263d27b9dc8 waiting on Deferred at 0x263d27b9f48> > >>> _ > <Deferred at 0x263d27b9dc8 waiting on Deferred at 0x263d27b9f48> > >>> client.lookupMailExchange('twistedmatrix.com <http://twistedmatrix.com/>') > <Deferred at 0x263d27c6a88 waiting on Deferred at 0x263d27c6c08> > >>> _ > <Deferred at 0x263d27c6a88 waiting on Deferred at 0x263d27c6c08> The reason you're getting this with a normal Python interactive interpreter is that the event loop which actually performs the I/O (does the DNS queries, in this case) isn't running at all, so the Deferreds are created, but never resolved. > Please help.
