我试图通过LWP :: UserAgent的连接到远程主机，但是当我试图使其与HTTPS工作，我收到一条消息，安装Perl模块，LWP ::协议:: HTTPS
LWP::Protocol::https need to be installed. (Perl 5.10.1, CentOS 6)
我试着用“CPAN”和“make”来安装这个模块，并且出现了一些错误。我还试图强制安装LWP::Protocol::https，现在它已安装在模块列表中（ExtUtils::Installed显示它），但脚本仍然写入501协议模式'https'不受支持（未安装LWP::Protocol::https）。
首先，我需要添加ExtUtils::CBuilder和ExtUtils::MakeMaker。然后我试图安装Crypt::SSLeay，但我收到的消息：

code is working properly. If you are behind a strict firewall or have no
network connectivity, these tests may fail (through no fault of the code).

错误消息意味着头在您的系统上找不到OpenSSL库。这些先决条件必须手动安装，例如通过你的系统包管理器。除了二进制库之外，您还需要开发资源来安装头文件。 – amon
@amon只是挑剔：已经安装了_library_（对'-lssl'的检查没有失败）。但头文件确实缺失。 –
感谢您的建议，我会尝试它并稍后留下评论 – tester3
