为什么“（base）”出现在我的终端提示符前面？

我想知道为什么我(base)的终端提示符左边有。

如果我source ~/.profile在终端中运行，它就会消失。

如果我关闭该终端并重新打开一个新终端，(base)它还会再次出现。

我想知道它是什么。

这是我的内容.profile（不包括标准$path内容和其他个性化内容）：

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
        . "$HOME/.bashrc"
    fi
fi

这是我的 .bashrc 的内容

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

答案1

这也可能是因为auto_activate_base设置为 True。您可以使用以下命令检查这一点

conda config --show | grep auto_activate_base

将其设置为 false

conda config --set auto_activate_base False
source ~/.bashrc

要重新激活，请将其设置为 True

conda config --set auto_activate_base True
source ~/.bashrc

答案2

这似乎来自您的环境。具体来说，您从您的环境中conda激活如下conda~/.bashrc

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

并conda activate在提示符前面加上(<env-name->)- 因为您没有指定特定的环境，所以默认为(base)。

该行为记录在使用 .condarc conda 配置文件：

更改命令提示符（changeps1）

使用 activate 时，将命令提示符从 $PS1 更改为包含激活的环境。默认值为 True。

例子：

changeps1: False

因此，为了消除它，请找到并修改您的.condarc文件 - 或者不要从您的~/.bashrc文件中激活 conda。

答案3

(base) 因 conda 环境的变化而出现。

以下命令隐藏（基本）环境。

conda config --set changeps1 False

答案4

从您的$HOME目录 中echo "changeps1: False" >> .condarc
