在Windows上安装Fabric（错误：没有名为Readline的模块）
我正在尝试在Windows上使用Fabric 0.1.1这个部署工具（http://docs.fabfile.org/），但是遇到了readline模块的问题。我查阅了很多讨论，但还是没能解决这个问题。这很重要，因为我们无法从Windows机器上部署应用程序。
C:\Documents and Settings\dev\Desktop\deploy>fab

安装这个模块时出现了：

有没有人解决过这个问题，或者能给出一些替代方案吗？

试试这个 readline 模块吧。它是专门为Windows设计的，可以在IPython中提供一些额外的功能，这些功能在默认情况下是没有的，可能会对你正在做的事情有所帮助。
按照以下步骤操作，我成功安装了：
2) 安装在默认的C:\Python27目录下。
3) 创建一个新文件夹：C:\Python27\Scripts
4) 把C:\Python27和C:\Python27\Scripts添加到系统路径中：
5) 从这里下载distribute_setup.py到C:\Python27\Scripts文件夹。
6) 打开命令行，进入C:\Python27\Scripts目录，运行：'python distribute_setup.py'
7) 然后运行'easy_install pip'
8) 接着运行'pip install fabric'
9) 你可能会看到一个错误，提示PyCrypto无法安装。你可以从这里下载预编译的Windows二进制文件。运行这个文件来安装PyCrypto。
10) 再次运行'pip install fabric'，这时应该会显示一切都已安装。
11) 在另一个目录（比如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) 切换到这个目录，运行'fab hello:working'。你应该能看到输出：
Hello working!
Done.
你想用 easy_install 安装的 readline 模块是为 OS X 系统准备的，不适用于 Windows。虽然有一些可以在 Windows 上使用的替代品，但你可以先试着把 fabric 更新到一个更新的版本（现在有 0.9 版本）。
查看 0.9 版本的源代码后发现，它并不依赖于 readline。
