Ruby - 打开文件，查找并替换多行 [英] Ruby - Open file, find and replace multiple lines

问题描述

我是 ruby​​ 新手，希望有人能帮我弄清楚如何打开文件，然后使用 gsub 查找并替换多个条件.

I'm new to ruby and was hoping someone could help me figure out how to open a file, then using gsub to find and replace by multiple conditions.

这是我到目前为止所得到的，但这似乎不起作用，因为第二个替换 var 覆盖了第一个:

Here's what I got so far but this doesn't seem to work as the 2nd replace var overrides the first:

text = File.read(filepath)
replace = text.gsub(/aaa/, "Replaced aaa with 111")
replace = text.gsub(/bbb/, "Replace bbb with 222")
File.open(filepath, "w") {|file| file.puts replace}

推荐答案

将第三行改为

replace = replace.gsub(/bbb/, "Replace bbb with 222")
