在Windows上安装Fabric（错误没有调用Readline的模块）

Question

我正试图在Windows上使用Fabric 0.1.1部署工具（http://docs.fabfile.org/），我们遇到了一个关于readline模块的问题。我经历了很多次，但似乎解决不了这个问题。这很重要，因为我们不能从基于Windows的机器上部署应用程序。

C:\Documents and Settings\dev\Desktop\deploy>fab
Traceback (most recent call last):
  File "C:\python\Scripts\fab-script.py", line 8, in <module>
    load_entry_point('fabric==0.1.1', 'console_scripts', 'fab')()

**ImportError: No module named readline**

安装模块会导致：

**easy_install readline**

有人解决过这个问题吗？或者有人能提出解决办法吗？

Answer 1

试试这个readline。它是一个用于Windows的模块，允许IPython中的其他功能不是本机的，并且可能与您正在尝试的操作一起工作。

Answer 2

遵循这些步骤对我很有效：

1）使用here中x86的MSI installer安装。

2）安装在默认的C:\ Python27目录中。

3）创建一个新目录：C:\Python27\Scripts

4）在系统路径中添加了C:\ Python27和C:\ Python27\Scripts：

5）将distribute_setup.py从here下载到C:\ Python27\Scripts

6）打开一个命令行，导航到C:\Python27\Scripts，运行：“python distribute\u setup.py”

7）现在运行“easy_install pip”

8）现在运行“pip install fabric”

9）如果说无法安装PyCrypto，则会出现错误。您可以从here下载预构建Windows binary。运行此命令安装PyCrypto。

10）再次运行“pip install fabric”，它应该会显示所有内容都已安装。

11）在另一个目录中（比如说c:\ dev\hello）创建一个fabfile.py并添加以下代码：

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

12）cd到这个目录并运行“fab hello:working”。你应该看到输出说

Hello working!

Done.

Answer 3

试图用readline安装的easy_install模块是用于OS X的，而不是windows。有一些与Windows兼容的readline替代品，但也许您应该首先尝试将fabric本身更新为更新的版本（0.9现在就在那里）。

重新映射0.9版本的源文件时，找不到对readline的任何依赖项。
