perl - Math::TrulyRandom 模块的 Dmake 文件错误

Question

我在尝试安装 Math::TrulyRandom 时听取了这个人的建议(随机数生成器与伪随机)，我正在运行“dmake”，他告诉我询问另一个问题的错误。

我的第一个问题是 here .

以下是终端出现的问题:

Math::TrulyRandom 已损坏，不应(实际上，不能)使用。

它写于 1996 年，只能在当时存在的某些 UNIX 系统(如 SunOS 4)上正常工作。它无法在现代 Linux 系统上生成随机数据，并且在 Windows 上根本无法编译。

如果您需要随机数生成器和 rand不会削减它，寻找另一个模块。 Math::Random::Secure或 Crypt::Random ， 例如。
