Thank you for installing Miniconda3![yangyunhe@sdp Downloads]$# 再次连接终端，命令提示符会改变，base 代表目前的 python 环境是 base
(base) [yangyunhe@sdp ~]$

3. 虚拟环境操作

miniconda 是为当前用户安装的，conda 初始化之后，修改了用户的 .bashrc 文件

if [ $? -eq 0 ]; theneval "$__conda_setup"
elseif [ -f "/home/yangyunhe/miniconda3/etc/profile.d/conda.sh" ]; then. "/home/yangyunhe/miniconda3/etc/profile.d/conda.sh"elseexport PATH="/home/yangyunhe/miniconda3/bin:$PATH"fi
fi
unset __conda_setup

# 查看 python 版本
(base) [yangyunhe@sdp ~]$ python -V
Python 3.12.9# 创建虚拟环境
(base) [yangyunhe@sdp ~]$ conda create -n testenv python=3.11
# 激活虚拟环境
(base) [yangyunhe@sdp ~]$ conda activate testenv
(testenv) [yangyunhe@sdp ~]$# 查看 python 版本
(testenv) [yangyunhe@sdp ~]$ python -V
Python 3.11.11# 查看现有的环境（* 代表目前生效的环境）
(testenv) [yangyunhe@sdp lib]$ conda env list# conda environments:
#
base                   /home/yangyunhe/miniconda3
testenv              * /home/yangyunhe/miniconda3/envs/testenv# 切换环境
(testenv) [yangyunhe@sdp ~]$ conda activate base
(base) [yangyunhe@sdp ~]$# 退出所有 miniconda 环境，返回系统的 python 版本
(base) [yangyunhe@sdp ~]$ conda deactivate
[yangyunhe@sdp ~]$
[yangyunhe@sdp ~]$ python -V
Python 2.7.5# 删除环境
[yangyunhe@sdp ~]$ conda env remove -n testenv# 设置不自动启用 base 环境
[yangyunhe@sdp ~]$ conda config --set auto_activate_base false

测试

# .condarc 有两个文件，/home/${user}/.condarc 和 /home/${user}/miniconda3/.condarc
# 都得修改，可以删除 /home/${user}/miniconda3/.condarc
(base) [yangyunhe@sdp ~]$ cp /home/yangyunhe/miniconda3/.condarc /home/yangyunhe/miniconda3/.condarc.bak
(base) [yangyunhe@sdp ~]$ rm -f /home/yangyunhe/miniconda3/.condarc

5 pip 设置清华大学源

修改 ~/.pip/pip.conf文件

[yangyunhe@sdp miniconda3]$ mkdir -p ~/.pip
[yangyunhe@sdp miniconda3]$ vim ~/.pip/pip.conf[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = pypi.tuna.tsinghua.edu.cn# 校验
[yangyunhe@sdp miniconda3]$ ~/miniconda3/bin/pip config list
global.index-url='https://pypi.tuna.tsinghua.edu.cn/simple'
install.trusted-host='pypi.tuna.tsinghua.edu.cn'
