针对 5.18.2 和 5.20.1 版本的 HTTP::Tiny 测试的 Perl 安装失败

Question

我正在尝试使用 Perlbrew 在 CENTOS Linux 服务器上安装 Perl。我试过安装 5.16、5.18 的几个版本。和 5.20，但它们似乎都未能通过 HTTP::Tiny 进行相同的测试：

我注意到140_proxy.t 正在尝试使用http://localhost:8080 作为服务器测试。但是，我们已经在该端口上运行了一个 httpd。 002_croakage.t 甚至不包含任何测试。

所以，

• 这些通常被认为是不好的测试吗？
• 这是其他人遇到的问题吗？
• 这与我们当前在端口 8080 上运行的服务有什么关系吗？
• 如果我进行强制安装会有问题吗？
• 而且，为什么 HTTP::Tiny 运行测试？它不是安装时附带的标准 Perl 模块。

Answer 1

尝试不让您的服务在 8080 上运行？我猜这是你失败的唯一原因，但唯一确定的方法就是尝试。

有几个failing test reports，但与您遇到的错误无关，而且都与连接到外部服务器（google、github、twitter）有关。

而且，为什么 HTTP::Tiny 运行测试？它不是安装时附带的标准 Perl 模块。

它是自 Perl 5.13.9 以来随 Perl 发行版一起提供的标准 Perl 模块。
