        connection timed out -- see help r(2) for troubleshooting;
        An Internet connection has timed out.  This can happen when
        the initial attempt to make a connection over the Internet
        has not succeeded within a certain time limit.  You can
        change the time limit that Stata uses under this condition
        by typing set timeout1 #seconds.  Or, the initial connection
        was successful, but a subsequent attempt to send or receive
        data over the Internet has timed out.  You can also change
        this time limit by typing set timeout2 #seconds.  See
        [R] netio.

出现这样的错误是什么原因呢？是网速问题还是安装本身问题？
