无法安装LWP::Simple on cygwin

Question

我是一个Perl初学者，试图安装LWP::Simple on cygwin (CYGWIN_NT-6.3)，但它无法安装。安装似乎从一开始就出了问题。你能帮我解决这个问题吗？

$ perl -MCPAN -e'install "LWP::Simple"'

Answer 1

有一个用于LWP：perl-libwww perl的cygwin包

如果您需要HTTPS，您可能应该安装：perl-LWP-协议-https

Answer 2

您的cpan输出告诉您的是，LWP::Simple有17个先决条件模块(它需要这些模块才能正常工作)，您必须确保在cpan为LWP::Simple运行构建/测试/安装之前都安装了这些模块。

当cpan检测到您的系统上还没有安装先决条件时，您的cpan配置可以有三种可能的设置来进行操作：

1. 自动安装先决条件。
2. 问您是否安装先决条件。
3. 不要执行1或2，让您手动处理它们的先决条件。

请记住，这17人中的许多人也可能有自己的先决条件，所以让cpan自动安装这些先决条件通常是最简单的，而且通常也是安全的。

除非您看到cpan的输出明确表示安装失败，否则您做得很好。

因此，考虑到这个错误报告：Warning: Prerequisite 'WWW::RobotRules => 6' for 'MSCHILLI/libwww-perl-6.08.tar.gz' failed when processing 'GAAS/WWW-RobotRules-6.02.tar.gz' with 'make => NO'. Continuing, but chances to succeed are limited. MSCHILLI/libwww-perl-6.08.tar.gz make -- NOT OK Running make test Can't test without successful make Running make install Make had returned bad status, install seems impossible

你会想要找出为什么WWW:RobotRules未能安装。我会这样做的：

$ cpan
cpan[1]> look WWW::RobotRules
[The module is downloaded is needed and then a shell is opened into the download directory]
$ perl Makefile.PL
$ make
$ make test
[This is where failure is likely to occur - report the failure messages back to us]

或者只需通过perl_vendor安装setup.exe
