无法在@INC中找到CGI / Ajax.pm（@INC包含：

Question

当我使用shebang（＃！/ usr / local / bin / perl）时，错误就是那个

DBI connect（'SQLSERVER'，'ivr'，...）失败：[unixODBC] [驱动程序管理器]未找到数据源名称，并且未指定默认驱动程序（SQL-IM002）....

和

如果我使用shebang（＃！/ usr / bin / perl），那么我得到以下错误：

Can't locate CGI/Ajax.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib64/perl5/site_perl/5.8.7/x86_64-linux-thread-multi /usr/lib64/perl5/site_perl/5.8.6/x86_64-linux-thread-multi /usr/lib64/perl5/site_perl/5.8.5/x86_64-linux-thread-multi.... 

代码如下：

    #!/usr/bin/perl
    use strict;
    use DBI qw(:sql_types);
    use CGI;
    use CGI qw/:standard/;
    use CGI::Ajax;

    my $cgi = new CGI();

    my $ajax = new CGI::Ajax( 'saveStudInfo_JScript' => \&saveStudInfo_PerlScript );
    $cgi->header(-charset=>'US-ASCII');
    print $ajax->build_html($cgi,\&generateHTML);

Error
