推荐答案

此答案假定实际上已安装了模块，但未将其放置在perl所要查找的位置.

This answer assumes that the module is in fact installed, but not in a place that perl is looking for.

通常，Perl模块Statistics::Distributions将包含在名为Statistics/Distributions.pm的文件中.在Linux和类似系统上，可以使用locate命令快速搜索这些文件:

Generally, the Perl module Statistics::Distributions will be contained in a file called Statistics/Distributions.pm. On Linux and similar systems, one can search for these files quickly with the locate command:

locate Statistics/Distributions.pm

如果已安装，locate将吐出一条类似于

If it is installed, locate will spit out a line similar to

/opt/my_perl/lib/Statistics/Distributions.pm

然后，您也可以指示perl解释器以各种方式在此路径中查找.一种是定义环境变量PERL5LIB，即从bash:

You can then instruct the perl interpreter to look in this path, too, in various ways. One is to define the environment variable PERL5LIB, i.e. from bash:

prompt> PERL5LIB=/opt/my_perl/lib/ ./myscript.pl

或者您可以使用perl -I开关:

prompt> perl -I/opt/my_perl/lib/ ./myscript.pl

或者您可以将脚本修改为use lib；有多种方法可以做到；-)

Or you can modify the script to use lib; there is more than one way to do it ;-)
