由于我使用过perl，但是最近我正在深入研究一个使用DateTime :: Astro的已建立的perl项目。即使使用--force，我一直在尝试安装模块并失败。我尝试了3种不同的方式，不知道从哪里开始：
perl -MCPAN -e shell错误

答案 0 :(得分：5)
你展示的cpanm输出非常有用：C编译器抱怨它无法找到mpfr.h：
xs/dt_astro.h:9:18: error: mpfr.h: No such file or directory
在基于Debian的GNU / Linux发行版上，mpfr.h是libmpfr-dev package的一部分。安装使得安装DateTime :: Astro工作（在Debian unstable上试过）。
其他发行版可能有一个类似命名的GNU MPFR开发文件包。
