Ubuntu 安装pandas

记录一下安装pandas的步骤以及输出：

启动python解释器，调用系统默认Python环境

bash
展开代码
(base) cc@LAPTOP-2A2OV24P:~$ python
Python 3.13.5 | packaged by Anaconda, Inc. | (main, Jun 12 2025, 16:09:02) [GCC 11.2.0            ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

检查Python路径，显示默认Python解释器的实际路径

bash
展开代码
(base) cc@LAPTOP-2A2OV24P:~$ which python
/home/cc/miniconda3/bin/python  #输出

检查Conda路径，确认Conda的安装位置

bash
展开代码
(base) cc@LAPTOP-2A2OV24P:~$ which conda
/home/cc/miniconda3/bin/conda

直接调用绝对路径的Python：/home/cc/miniconda3/bin/python→ 效果与步骤1相同

bash
展开代码
(base) cc@LAPTOP-2A2OV24P:~$ /home/cc/miniconda3/bin/python
Python 3.13.5 | packaged by Anaconda, Inc. | (main, Jun 12 2025, 16:09:02) [GCC 11.2.0            ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

尝试创建新Conda环境→ 准备创建名为 py310的新环境

bash
展开代码
conda create -n py310

激活py310环境，并检查python路径

bash
展开代码
conda activate py310
which python

实践：

bash
展开代码
(base) cc@LAPTOP-2A2OV24P:~$ conda activate py310
(py310) cc@LAPTOP-2A2OV24P:~$ conda env list

# conda environments:
#
base                   /home/cc/miniconda3
py310                * /home/cc/miniconda3/envs/py310

(py310) cc@LAPTOP-2A2OV24P:~$ which python
/home/cc/miniconda3/envs/py310/bin/python

切换回base环境，并验证python路径

bash
展开代码
conda activate base
which python

实践：

bash
展开代码
```bash
(py310) cc@LAPTOP-2A2OV24P:~$ conda activate base
(base) cc@LAPTOP-2A2OV24P:~$ which python
/home/cc/miniconda3/bin/python

不同环境有独立的Python解释器路径（envs/py310/bin/vs 主bin/目录）
在py310安装的包不会影响base环境

返回py310环境安装pandas

bash
展开代码
conda activate py310
pip install pandas

在特定环境下执行的命令（如pip install）仅作用于当前环境
