conda 在没有 .condarc 的情况下从哪里获取默认配置值？
Where does conda get the default configuration values without a `.condarc`?
我去寻找一些 conda 设置。 （如果你一定要知道，这与搞乱我的 bash 的 $PS1 有关 - 决定是使用 conda 的配置还是环境变量。）为了找到设置，指令是查看 .condarc。要查找 .condarc，我被指示使用 conda config --show-sources。我这样做了，结果是：
(base) [bballdave025@MYMACHINE ~]$ conda config --show-sources
(base) [bballdave025@MYMACHINE ~]$
即它是空白的。浏览 some conda documentation（以及它建议浏览的路径）也没有产生任何 .condarc。我在其他地方进行了自己的搜索，但仍然一无所获。 没关系 - 我可以没有 .condarc（而且我知道我可以创建一个，通过 touch $HOME/.condarc 或通过 conda config --set changeps1 False - 或任何 conda config --set <param-name> <value>).
但是，当我查看配置参数（设置或默认值）时，我 肯定 看到了一些值。用于查看这些值的一些命令是 conda info、conda config --show 和 conda config --describe。在我提出我的主要问题后，我将提供这些命令的详细信息。
这个问题几乎可以肯定是学术性的，但我不知道这让我发疯：这些价值观来自世界何处？它们必须来自 某处。我想它是某种文件，无论是本地的还是在线的，无论是基于文本的还是纯二进制的。我没有运气找到来源；显然，它不在任何 .condarc 中，但它也不在我搜索过的其他任何地方。 conda 从哪里提取这些值？
此 post 的其余部分包含情况的详细信息以及我试图找到答案的尝试。真正的基础都在post以上这一点。另一条快速说明：由于它们可能会有用，因此有关我的系统和 conda info 的信息位于此 post.

显示情况的命令
这里有一些命令可以显示缺少 .condarc 和显示 parameters/settings.

重复，
