如何使用Ruby删除回车符，而不用“

如何使用Ruby删除回车符，而不用“ - ”或空格替换(How do I remove carriage returns with Ruby without replacing it with “-” or blank space)

我想从以下位置删除回车符：

"LIC_001 \r\n ,\r\n LIC_002 \r\n "

我希望价值如下：

"LIC_001 , LIC_002 "

我试过了：

"LIC_001 \r\n ,\r\n LIC_002 \r\n ".gsub!("\r\n", " - ")

请建议我如何做到这一点。

I want to remove carriage returns from:

"LIC_001 \r\n ,\r\n LIC_002 \r\n "

I want the value to be like:

"LIC_001 , LIC_002 "

I tried:

"LIC_001 \r\n ,\r\n LIC_002 \r\n ".gsub!("\r\n", " - ")

Please suggest how I can do this.

这应该可以做到这一点：

"LIC_001 \r\n ,\r\n LIC_002 \r\n ".squish #=> "LIC_001 , LIC_002"

This should do the trick:

"LIC_001 \r\n ,\r\n LIC_002 \r\n ".squish #=> "LIC_001 , LIC_002"
