如何摆脱语法错误，意外的keyword_end，期待输入结束？

Question

我得到了

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

尝试安装和测试ruby时，在命令提示符下

。

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

代码遗失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应为timestamp。 （这不是语法错误的直接原因）。
