康达安装 WGET 后的康达"No module named wget"

Question

Conda似乎已经将包wget作为二进制文件安装在/bin中，但没有安装在环境的站点包中：

$ conda activate geo
(geo) $ find /home/tams00/anaconda3/envs/geo/bin/ -name "wget*"
/home/tams00/anaconda3/envs/geo/bin/wget
(geo) $ find /home/tams00/anaconda3/envs/geo/lib/ -name "wget*"
(geo) $

请参阅以下错误：

(geo) $ conda --version
conda 4.7.12
(geo) $ python --version
Python 3.7.3
(geo) $ which python
/home/tams00/anaconda3/envs/geo/bin/python
(geo) $ conda install wget
Collecting package metadata (repodata.json): done
Solving environment: done

wget                      1.20.1               h20c2e04_0
(geo) $ python -c "import wget"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'wget'
(geo) $

程序wget与Python包wget不同。后者的名称为python-wget，可以从Conda Forge 安装

conda install -n geo conda-forge::python-wget

这是具有包含来自许多编程语言的包的通用包管理器的固有问题之一。我看到的工作惯例是，每当出现冲突时，都要为语言做准备。Python包通常得到py-或python-，R得到r-等
