Windows + fab = ImportError: cannot import name output

[bitprophet]

Description

Getting the following when trying to do anything with Fabric. This same fabfile.py that I'm using works just fine on Linux and Mac. I've got Paramiko and PyCrypto installed. Python 2.6 amd64, Windows 7 64-bit, Fabric 0.9.1. Any help would be greatly appreciated. I think there were a few other Windows users running into this, too.

(Here's another user with the same problem that is also a 64-bit guy)

(Tweaked description formatting a bit...)

Going by your traceback you don't seem to have Paramiko installed, and it's possible that the abort call is running into additional problems due to that. Can you install Paramiko and then see if it works? (I'll still take the "blows up real good instead of displaying nice useful message, when Paramiko not installed" issue aside, though, if that's the case.)

The SO link is also probably the same issue, though his rather unhelpfully truncated traceback makes it hard to tell.

Digging deeper, looks like Paramiko installed, as did its PyCrypto dependency. It looks like it failed to install a PyCrypto dependency, but marked everything as OK. Looks like winrandom is missing or built for a different environment.

This isn't Fabric's problem, so it's safe to close this.

OK, thanks for checking (and submitting the report here instead of just posting it on SO like some people do :)).

If you find something with your setup that seems like a common hang-up that might deserve mention in the install docs, please let me know.

I guess the real problem to note here is that on 64 bit Python, you're S.O.L. for a 64bit precompiled winrandom. Rather than let the user know this, pip merrily chugs along as PyCrypto says it installs just fine (whereas it really doesn't, winrandom just never gets tested). If you have MS Visual Studio, this link seems to suggest that it will compile this for you.

So meh. Unless you have a compiler, you need to wait until someone compiles a 64bit winrandom and packages it. Otherwise, install MS Visual C++ and compile it yourself (pain).

FWIW, I came across this issue today and had some problems even with PyCrypto and winrandom installed before installing fabric/paramiko. The first error was the traceback reported in the first post. But then "ImportError: No module named OSRNG" occured when paramiko tries to "from Crypto import Random". For me it worked after downgrading pyCrypto from 2.3 to 2.1 on 32bit windows.
