Question

我目前在IE11中遇到正则表达式问题（为什么有些人仍在使用它使我感到困惑）。而且我在IE的控制台中收到以下错误：

RegExp(/^http/,"i"); //Syntax error in regular expression

我在堆栈溢出with kind of the same issue中发现了一条帖子，该问题的答案是XRegExp可能是关键。

为了进行尝试，我正在寻找一种在rails中安装和实现该库的方法，并找到了名为xregexp-rails

的gem。

所以我想知道如何在rails 5中实现这个gem，以便能够尝试解决我的问题。

更新

尝试安装所述gem在运行捆绑软件，捆绑软件安装和捆绑软件更新后在控制台中显示以下错误：

    Bundler could not find compatible versions for gem "railties":
  In snapshot (Gemfile.lock):

  In Gemfile:

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
