Installing Fabric On Windows (Error No Module Called Readline)

问题:

I'm trying to use the Fabric 0.1.1 deploy tool (http://docs.fabfile.org/) on Windows and we're running into an issue with the readline module. I've been through various threads but can't seem to solve the issue. It's important because we can't deploy applications from Windows based machines.

C:\Documents and Settings\dev\Desktop\deploy>fab Traceback (most recent call last):   File "C:\python\Scripts\fab-script.py", line 8, in      load_entry_point('fabric==0.1.1', 'console_scripts', 'fab')()   File "c:\python\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py" , line 277, in load_entry_point   File "c:\python\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py" , line 2180, in load_entry_point   File "c:\python\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py" , line 1913, in load   File "build\bdist.win32\egg\fabric.py", line 25, in  **ImportError: No module named readline**

Installing the module results in:

Has anybody solved this issue or can anybody suggest a workaround?

回答1:

The readline module you are trying to install with easy_install is for OS X, not windows. There are Windows-compatible replacements for readline out there but perhaps you should first try updating fabric itself to a more current version (0.9 is out there now).

Grepping the source of the 0.9 version does not find any dependencies on readline.

Following these steps exactly worked for me:

1) Installed using the MSI installer for x86 from here.

2) Installed in the default C:\Python27 directory.

3) Create a new directory: C:\Python27\Scripts

4) Added C:\Python27 and C:\Python27\Scripts to the system path:

5) Download the distribute_setup.py from here into C:\Python27\Scripts

6) Open a command line, navigate to C:\Python27\Scripts, run: 'python distribute_setup.py'

7) now run 'easy_install pip'

8) now run 'pip install fabric'

9) You should get an error saying PyCrypto couldn't install. You can download the pre-build Windows binary from here. Run this to install PyCrypto.

10) run 'pip install fabric' again and it should say everything is installed.

11) in a different directory (let's say c:\dev\hello) create a fabfile.py and add the following code:

def hello(name="world"):     print("Hello %s!" % name)

12) cd to this directory and run 'fab hello:working'. You should see output say

Hello working!  Done.

Give this readline a try. It is a module for Windows that allows additional features in IPython that aren't native and might work with what you are trying to do.

回答4:

0.1.1 is an older version, I believe. I have no problem installing Fabric on Windows with ActivePython (w/ PyPM):

C:\> pypm install fabric Ready to perform these actions: The following packages will be installed:  fabric-0.9.0 pycrypto-2.0.1 Get: [pypm.activestate.com] fabric 0.9.0-1 Get: [pypm.activestate.com] pycrypto 2.0.1-1 Installing fabric-0.9.0 Fixing script C:\Users\sridharr\AppData\Roaming\Python\Scripts\fab-script.py Installing pycrypto-2.0.1

回答5:

1. Download and run easy_install installer for your python version from http://pypi.python.org/pypi/setuptools#downloads . ie: setuptools-0.6c11.win32-py2.6.exe
2. On the command prompt, lauch easy_install -U fabric to install the last fabric release.

回答6:

Readline should be available with Cygwin, if you want to move your entire stack in that direction.
