无法导入美化组和请求

Question

我用的是Python。我已经安装了Beautifulsoup和请求模块。它还显示在我安装的软件包列表中

但是，当我尝试从conda提示符运行python文件时，会出现错误“没有名为'bs4'的模块/”没有名为'requests'的模块

已安装的软件包：

我完全被阻止了，尝试了谷歌搜索，pip也安装了，但没有运气。非常感谢您在这个问题上提供的任何帮助

Answer 1

在conda terminal中，使用选项-n安装模块，命名所需的环境

我创建了一个环境“branchenv”和另一个环境“python385”。对于每个od：

conda install -c anaconda beautifulsoup4 -n python385
conda install -c anaconda beautifulsoup4 -n branch-env

Answer 2

您是否有多个python安装？在终端、powershell等中尝试以下操作

$ python
<Do you get a python prompt. If yes, then>
>>> import requests
<Is it able to import or does it show any error?>

如果上述操作无效，请尝试以下操作：

$ python3
<Do you get a python prompt. If yes, then>
>>> import requests
<Is it able to import or does it show any error?>

让我知道你在这方面有什么错误。如果没有，那么希望它能起作用
