无法在@INC中找到POE / Component / Client / HTTP.pm

Question

我正在尝试运行这个perl Web代理代码link，但我有一个错误，说我缺少HTTP.pm！

消息：

final ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine engine = mgr.getEngineByName("JavaScript");
System.out.println("neq: " + engine.eval("a1 = NaN; a1!=a1;"));
System.out.println("eq: " + engine.eval("a1 = NaN; a1==a1;"));
System.out.println();
engine = mgr.getEngineByName("JavaScript");
System.out.println("eq: " + engine.eval("a1 = NaN; a1==a1;"));
System.out.println("neq: " + engine.eval("a1 = NaN; a1!=a1;"));
System.out.println();
engine = mgr.getEngineByName("JavaScript");
engine.eval("a1 = NaN;");
System.out.println("neq: " + engine.eval("a1!=a1;"));
System.out.println("eq: " + engine.eval("a1==a1;"));
System.out.println();
engine = mgr.getEngineByName("JavaScript");
engine.eval("a1 = NaN;");
System.out.println("eq: " + engine.eval("a1==a1;"));
System.out.println("neq: " + engine.eval("a1!=a1;"));

那么，我应该安装什么才能运行此代码。 谢谢，

您需要安装Perl模块POE::Component::Client::HTTP。如果您有权访问，请尝试从命令行运行：

perl -MCPAN -e 'install POE::Component::Client::HTTP'
