Use putssince it will automatically add a newline for you:
使用，puts因为它会自动为您添加换行符：
puts "Hi"
puts "Hi"
If you want to make an explicit newline character then you'll need to know what kind of system(s) on which your program will run:
如果你想创建一个显式的换行符，那么你需要知道你的程序将在什么样的系统上运行：
print "Hi\n" # For UNIX-like systems including Mac OS X.
print "Hi\r\n" # For Windows.

You could avoid the two print statements and instead only use one line.
您可以避免使用两个打印语句，而只使用一行。
print "Hi\r\nHi"
Or if you want to use two lines then
或者如果你想使用两行然后
print "Hi\r\n"
print "Hi"

You can create a space by adding a string with only a space in it between the 2 other strings. For example:
您可以通过在其他 2 个字符串之间添加一个只有一个空格的字符串来创建一个空格。例如：
print "Hi" + " " + "Hi"

puts "\n" works also on Win/Ruby ruby 2.4.2p198 and even "\n"*4 for multiplication of new rows (by 4)
puts "\n" 也适用于 Win/Ruby ruby 2.4.2p198 甚至 "\n"*4 用于新行的乘法（乘以 4）
