Ruby watir環境搭建在實際操作中可能會遇到一些問題，往往這些小錯誤會使經驗不太豐富的新手們甚為頭疼。在這里我們就為大家詳細介紹一下Ruby watir環境搭建時出現的錯誤解決辦法。#t#

Ruby watir環境搭建完成后用下面例子來測試:

require 'watir'
ie = Watir::IE.new
ie.goto('http://www.g.cn')

如果能夠打開'http://www.g.cn'就說明安裝成功

可惜我沒有安裝成功，提示以下Ruby watir環境搭建錯誤

在谷歌搜索找到這個網址 http://www.zhuaijun.cn/archives/53 ，他的原帖是:

出現這個Ruby watir環境搭建問題是因為windows-pr版本的問題引起了。
0.9.3版本有個小問題
結果的辦法是先Gem uninstall
windows-pr
然后再運行 Gem install windows-pr

OK，Ruby watir環境搭建出現的錯誤已經搞定。
