CPAN 安装失败 Algorithm::CurveFit

Question

我正在尝试通过在我的 Ubuntu 虚拟机的终端输入 cpan Algorithm::CurveFit 来安装 Algorithm::CurveFit。

但是，这个returns出现以下错误：

如何按照摘要报告底部的建议检查reports？

更重要的是，如何解决这些错误并安装 Algorithm::CurveFit？

Answer 1

如果从包中下载的源文件 CurveFit.pm 在某处符号链接到 @INC，则包 Algorithm:::CurveFit 将正常工作（显然）。

但是、CurveFit.pm应该修改为CurveFit被调用，而不是Algorithm::CurveFit
