Question

我目前正在尝试在我的电脑上安装watir，但目前正在点击下面的错误，我想不出为什么会这样？

我按照以下步骤安装：

Download ruby 1.9.2: 
http://www.ruby-lang.org/en/downloads/
 Install.

Download RubyGems:
 http://rubygems.org/pages/download
 Install.

Download the DevKit so that native extensions can be built:
     ruby dk.rb init
     ruby dk.rb review
     ruby dk.rb install

gem update --system (or to do more quickly: gem update --system --no-rdoc --no-ri)
     gem install watir

当我这样做时，我得到的是下面的错误日志。有谁知道我怎么能让Watir安装好吗？

我完全不知道如何纠正这个问题。我在XP x86和Win 7 X64上都尝试过这一点无济于事。

提前致谢安迪

Answer 1

FFI的更高版本一直是一些问题的根源，因为它们不再包含本机Windows版本并且必须动态构建一个版本，但也因为与watir或webdrivers的一些不兼容性

尝试这样做

gem uninstall ffi 
 (just in case there is anything that managhed to get installed)
gem install ffi -v 1.0.9

然后安装watir或watir-webdriver

<强>更新最新版本的FFI可以与Watir和Watir-Webdriver一起使用，但不像早期版本那样“预编译”。所以要在PC上安装它们如果你还没有它，你需要得到Devkit。一旦安装了devkit并为其运行了安装脚本，就可以使用gem install ffi来安装最新的FFI gem，它应该可以正常工作。

Answer 2

我已经更新了有关如何在Windows上安装Watir的说明。如果您遵循它们，您将能够安装最新版本的Ruby，Watir和ffi。

Watir不会安装XP x86或Win 7 x64。获取错误为FFI gem构建原生扩展
