推荐答案

我假设您正在谈论在 Windows 机器上使用 Watir.根据我的经验，以正确的方式安装 Ruby 是最困难的部分.

I'm assuming you're talking about using Watir on a Windows machine. From my experience installing Ruby in the correct way is the most difficult part.

首先，像在 32 位系统上一样安装所有内容.64 位安装通常会带来不必要的问题.

First of all, install everything as if you're on a 32 bit system. The 64 bit installation often brings unwanted issues.

也就是说，ffi gem 也会导致问题，因此您必须卸载它，并使用特定标签重新安装:

That said, the ffi gem can also cause issues, so you'll have to uninstall it, and re-install with specific tags:

gem uninstall ffi
gem install ffi --platform ruby

最后，显示 LoadError: cannot load such file -- watir-classic 的错误只是意味着您正在尝试使用不存在的某个 gem.在这种情况下 watir-classic，所以以下应该解决这个问题:

Finally, the error that is showing LoadError: cannot load such file -- watir-classic simply means that what you're doing is trying to make use of a certain gem that is not there. In this case watir-classic, so the following should fix that:

gem install watir-classic
