Ubuntu下 /usr/lib/* 内容恢复
Jul 29th, 2021
有一次处理 Ruby 的版本问题，删除了/usr/lib/ruby文件夹，然后导致了ruby 出现各种问题。
那么怎么解决呢，重做系统，其实大可不必。在 Ubuntu 下使用这个方法即可。
raw_pkgs = `dpkg --get-selections`.split("\n")
need_reinstall = []
path="/usr/lib/ruby"
raw_pkgs.each do |x|
pkg = x.split(" ")[0]
if `dpkg -L #{pkg}`.include? path
puts "-> #{pkg} has files in #{path}"
need_reinstall << pkg
end
end
puts "\nYou need to reinstall #{need_reinstall.size} packages:"
puts "\tsudo apt-get install --reinstall " + need_reinstall.join(" ")
上面的内容保存成ruby脚本或者使用irb后复制粘贴执行即可。
最后会得到一个sudo apt-get install --reinstall xxxxxx 的内容。 然后在终端 执行得到的输出内容即可。
