如何摆脱语法错误，意外的keyword_end，期待输入结束？

Question

我在命令提示符尝试安装和测试红宝石时得到

syntax error, unexpected keyword_end, expecting end-of-input 

。

require 'mysql2' 

client = Mysql2::Client.new(host: 'localhost', username: 'root', password: 'password1') 

sql = 'select now() as timestamp' 

result = client.query(sql) 
    puts row['time stamp'] 
end 

Answer 1

代码丢失do。

client = Mysql2::Client.new(host: 'localhost', username: 'root', password: 'password1') 

sql = 'select now() as timestamp' 

result = client.query(sql) do # <---- 
    puts row['timestamp'] 
end 

仅供参考，time stamp应该timestamp。 （这不是语法错误的直接原因）。
