Perl 无法安装 Net::SSL

Question

为了安装RT4.2，我尝试安装Net::SSL，但没有成功。 这是输出：（Ubuntu Server12.04，perl 5.14.2）

当我选择不测试连接的N个选项时，也无法成功。

The test suite can attempt to connect to public servers to ensure that the
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).

Answer 1

更重要的是，我希望你用的是perlbrew或plenv基础的环境，因为你已经至少困扰安装cpan ，而不是依赖于默认套餐。

因此，您似乎缺少系统上SSL的库和标头，请通过以下方法解决此问题：

sudo apt-get install libssl-dev

而且，如果还没有，请使用上面链接的方法之一来设置环境，并使用cpanminus作为一种非常有用的工具来补充这两种方法。

Answer 2

您的问题是构建后的测试不成功，并且此文件t / 01-connect.t第11行发生错误。

eval {
    $sock = Net::SSL->new(
        PeerAddr => '127.0.0.1',
        PeerPort => 443,
        Timeout  => 3,
    );
};

我可以假设某些进程已经在监听127.0.0.1 443端口。 尝试停止它，然后以所需的方式重新安装。 应始终通过测试。

Answer 3

一个很老的问题，但我也一直在寻找这个问题

与其尝试使用 CPAN 安装 Perl 的 SSL 模块，不如像@TLP 在他们对原始问题的评论中所说的那样，使用 Ubuntu 包管理器

apt-cache search net-ssl

会给出一个包列表。 例如：

apt install libnet-ssleay-perl
apt install libcrypt-ssleay-perl

这些在 Perl v5.20 和 v5.30 上对我有用。 您将不得不使用apt-cache search搜索以查看哪些库适合您的库
