切换默认conda2023-02-27

因为同时安装了mamba和anaconda3，而默认使用mamba的时候有些包的运行会出错误，所以打算切换回原先conda。

# conda environments:
#
                         /path/anaconda3
base                  *  /path/mambaforge-pypy3

主要是修改~/.bashrc。
如果只有一个默认设置应该是这样的。

 >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/path/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/path/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/path/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/path/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup

使用了mamba的是这样的配置

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/path/mambaforge-pypy3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/path/mambaforge-pypy3/etc/profile.d/conda.sh" ]; then
        . "/path/mambaforge-pypy3/etc/profile.d/conda.sh"
    else
        export PATH="/path/mambaforge-pypy3/bin:$PATH"
    fi
fi
unset __conda_setup

if [ -f "/path/mambaforge-pypy3/etc/profile.d/mamba.sh" ]; then
    . "/path/mambaforge-pypy3/etc/profile.d/mamba.sh"
fi
# <<< conda initialize <<<

将/path/mambaforge-pypy3替换为/path/anaconda3
source ~/bashrc更新设置
再启动新的窗口就是用了anaconda3

# conda environments:
#
base              */path/anaconda3
                   /path/mambaforge-pypy3
