Ruby page.rb:220:警告：在行中间遇到\r，在Mac上被视为一个空白

我正在尝试在ruby cucumber、selenium webdriver和框架中运行测试。测试是在windows机器上编写的，我正在使用Mac。我得到以下错误。我在这个Git hub链接上发现- 这是可以解决的。我知道我需要安装“kpeg gem”，但它并没有解决问题

你能帮忙吗？我想知道修复它的步骤，以便于您更好地理解所提供链接上的文档。我将不胜感激

我不认为

\r

是您向我们展示的堆栈中最大的问题

若要删除

\r

，请在您喜爱的文本编辑器中打开有问题的文件，并确保将行尾从windows样式（\r\n）替换为mac样式（\n）

您还应该阅读堆栈跟踪告诉您的其他错误和警告：

以及：

这也有望解决下一个问题，即

---

问题出在Windows样式的行尾（\r\n）。在某些文本编辑器的行尾处，您可能会看到^M个结尾

在linux上，您可以使用dos2unix修复行尾：

dos2unix /Users/yc98ag2/Documents/Git/astra/lib/new_ui/pages/mew2/catsplash_page.rb

在mac上还有另一种解决方案：

mv catsplash_page.rb catsplash_page.rb.bak
cat catsplash_page.rb.bak | col -b > catsplash_page.rb

---

根据我的经验，当您从某处复制和粘贴代码时，也会出现此问题。从头开始重新键入代码应该可以修复它

我是如何解决的：

将代码复制并粘贴到普通编辑器中（我使用了Mac的默认文本编辑器）

代码的清晰格式（我切换到普通模式）

删除存在此问题的文件

创建同名的新文件

从纯文本编辑器复制并粘贴代码并保存

---

这应该可以解决问题。

对于其他错误，您有什么建议吗？
