Question

我是getopt的新手：很久。我试图通过命令行指定变量但不知道如何声明变量。请参阅下面的错误。

感谢任何帮助，

$ perl make_keggTable.pl -i ko2genes.pau -o pau
全局符号“$ inlocus”需要在make_keggTable.pl第126行显式包名全局符号“$ inlocus”需要在make_keggTable.pl第126行显式包名全局符号“$ orgCode”需要在make_keggTable.pl第133行显式包名全局符号“$ orgCode”需要在make_keggTable.pl第146行显式包名。

您无需使用Getopt::Long::Descriptive声明其他标量变量。只需使用以下表示法：

open (IN, $opt->inlocus) or die "cannot open ", $opt->inlocus, "\n";
