Dear all,<br><br>I have a question about pyperl.<br><br>there is a perl module <a href="http://test.pm">test.pm</a>:<br>#! /usr/bin/perl<br>package tset<br>sub Cal {<br>my ($v1,$v2)=@_;<br>my $result=$v1+$v2;<br>}<br>print "this is a test \n";<br>
1;<br><br>And there is a python file that calls the module above,<br>import perl<br>perl.require("test");<br>#perl.call("Usage","<a href="http://test1.pl">test1.pl</a>")<br>#perl.call("test::Usage", "1")<br>
b=perl.call("test::Cal", 1, 1)<br>print b<br><br>when run, I got a error message shown below: (can anyone tell me the reason? many thanks)<br><span style="background-color: rgb(255, 0, 0);">##################################error message####################</span><br clear="all">
