我最近一直在研究一些python，我想我已经理解了“环境”的概念(主要是通过pip youtube教程，只为了与需要的人：1、2分享)。
我尝试了相同的概念理解，这次使用Anaconda (来源)，下面是我的命令：
代码语言：javascript复制conda create -n testconda python=3.8 anaconda(...yes ...进入..。是的.)
代码语言：javascript复制conda activate testconda 我注意到它开始安装大量的软件包，我知道其中一些(比如“水瓶”)是不必要的。
(文章末尾的__conda list输出)
因此，据我所知(在youtube教程之后，pip只安装所需的软件包(准备我的env和后者--取决于我在env中安装了什么)。
为什么Anaconda要安装所有这些软件包？是否有办法将设置更改为仅需要的包？我知道有些软件包应该安装在环境中，但我认为有些包不能.
