perl - 如何从 CPAN 安装 `Thread::Pool`？

Question

我正在使用 cpanm 安装 Perl 模块，但由于某些原因我无法安装 Thread::Pool:

$ sudo cpanm Thread::Pool

失败并且日志文件显示:

嗯，问题是Thread::Tie (先决条件之一)未通过测试。根据CPAN Testers , Thread::Tie 从未通过其在 Perl 5.10.1 上的测试，并且有 6 次失败报告。我查过的这对夫妇看起来和你的一模一样。

您可以使用 cpanm -n 跳过运行测试并安装，但不能保证生成的模块会正常工作。问题可能出在测试脚本而不是模块本身，但这不是最可能的解释。

你可以试试reporting a bug in Thread::Tie , 或尝试自行调试。
