为什么 Anaconda 在我的基础环境中显示模块?

[英]Why is Anaconda showing modules in my base environment?

I have been using Anaconda to build various environments.我一直在用Anaconda搭建各种环境。 I noticed that if I use conda list in my base, Anaconda outputs many installed modules.我注意到如果我在我的基础中使用conda list ,Anaconda 会输出许多已安装的模块。

What are all of these modules?所有这些模块是什么?

Were they installed during the initial installation of the Anaconda?它们是在 Anaconda 的初始安装期间安装的吗? If so, how can you tell?如果是这样,你怎么知道?

Does having modules in my base create problems?我的基地中有模块会产生问题吗? If so, how do I properly remove them?如果是这样,我该如何正确删除它们?

Having packages installed in base is not a problem, though many users prefer a minimal base installation, such as Miniconda or a Miniforge variant, which only include what is essential to run the conda (or mamba ) CLI.base中安装软件包不是问题,尽管许多用户更喜欢最小的基本安装,例如 Miniconda 或 Miniforge 变体,它们只包含运行conda (或mamba )CLI 所必需的内容。

Mutating 2 packages in base is prone to breaking the Conda installation .改变base中的2 个包很容易破坏 Conda 安装 So, I don't recommend using the base for work (especially not the Python in there), and recommend Mambaforge for fresh installs.因此,我不建议使用基础进行工作(尤其不是其中的 Python),并建议使用 Mambaforge 进行全新安装。


[1] Note that Conda installs packages , not modules . [1]请注意,Conda 安装的是,而不是模块 The term modules refers to what Python packages bundle, but many of the Conda packages are non-Python dependencies.术语模块是指 Python 包捆绑的内容,但许多 Conda 包是非 Python 依赖项。

[2] That is, any conda (install|remove|update) -n base operations. [2]即任何conda (install|remove|update) -n base操作。 Though it definitely is recommended to keep the conda package updated, ie, conda update -n base conda .虽然绝对建议保持conda package 更新,即 conda conda update -n base conda
