conda安装wget后，conda "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) $

请参阅下面的错误：

(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

# All requested packages already installed.

(geo) $ conda list wget
# packages in environment at /home/tams00/anaconda3/envs/geo:

# Name                    Version                   Build  Channel
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) $

Answer 1

wget程序包与Python包wget是不同的。后者的名称是python-wget，可以从Conda Forge安装

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

这是拥有一个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，只要有冲突，就在语言前加上前缀。Python包通常得到py-或python-，R得到r-等。
