rpy2不起作用 - 需要libiconv.so.2

Question

我有一个相对新鲜的anaconda安装,我使用"conda install rpy2"安装了rpy2.但是,当我尝试运行它时,我收到此错误,例如:

> /[dir]/anaconda/bin/python -m 'rpy2.tests'
Traceback (most recent call last):

    from rpy2.rinterface._rinterface import (baseenv,
ImportError: libiconv.so.2: cannot open shared object file: No such file or directory

这个libiconv.so.2是什么,为什么它不直接从盒子里工作？

我认为你需要conda install -c r libiconv或者可能安装r-essentials,其中包含libiconv.
