为什么“（base）”出现在我的终端提示前面？

根据标题，我想知道为什么我(base)在终端提示的左侧。

如果我source ~/.profile在终端上运行，它会消失。

如果我关闭该终端并重新打开一个新终端，(base)那又在那里。

我想知道它是什么，谢谢。

这是我的内容.profile（不包括标准$ path内容和其他个性化内容）：

# added by Anaconda3 installer
#export PATH="/home/jim/anaconda3/bin:$PATH"
. /home/jim/anaconda3/etc/profile.d/conda.sh
conda activate

我到处搜寻，但找不到答案。另一个用户问了同样的问题，但尚未得到回答：

• （base）已出现在终端机中我的名字之前。这是什么？以及如何删除它？

这似乎来自您的conda环境。特别是，您正在conda从~/.bashrc以下方面进行激活

# added by Anaconda3 installer
#export PATH="/home/jim/anaconda3/bin:$PATH"
. /home/jim/anaconda3/etc/profile.d/conda.sh
conda activate

并conda activate在提示前加上(<env-name->)-，因为您未指定特定的环境，默认为(base)。

使用.condarc conda配置文件中记录了该行为：

更改命令提示符（changeps1）

使用激活时，将命令提示符从$ PS1更改为包括激活的环境。默认值为True。

例：

changeps1: False

因此，要使其消失，请查找并修改您的.condarc文件-或不要从~/.bashrc文件中激活conda 。

这也可能是因为auto_activate_base设置为True。您可以使用以下命令进行检查

conda config --show | grep auto_activate_base

设置为假

conda config --set auto_activate_base False

（基数）由于conda环境的变化而出现。

以下命令隐藏（基本）环境。

conda config --set changeps1 False

要停用conda环境，请输入：

conda deactivate

这将删除(base)Linux提示符之前的，如下所示：

运行下面的代码，然后输入conda deactivate，基地就消失了。

echo >&2 "DeprecationWarning: 'source deactivate' is deprecated. Use 'conda deactivate'."
"$_CONDA_ROOT/etc/profile.d/conda.sh" || return $?

康达停用

它似乎仍然是Anaconda的实验功能。

要将其恢复为正常，可以运行以下命令：

conda init --reverse

然后，您需要关闭当前的shell窗口并打开一个新窗口以查看修改。
