conda环境管理命令

1.环境检查

1）查看安装了哪些包
conda list
2)查看当前存在哪些虚拟环境
conda env list
conda info -e

[root@oracledb anaconda3]# conda info -e
# conda environments:
#
base                  *  /home/anaconda3

3)检查更新当前conda
conda update conda

4)检查更新当前conda版本
conda -V
conda --version

[root@oracledb anaconda3]# conda -V
conda 4.5.11

5)conda环境

conda info

[root@oracledb anaconda3]# conda infoactive environment : baseactive env location : /home/anaconda3shell level : 1user config file : /root/.condarcpopulated config files : /root/.condarcconda version : 4.5.11conda-build version : 3.15.1python version : 3.7.0.final.0base environment : /home/anaconda3  (writable)channel URLs : https://repo.anaconda.com/pkgs/main/linux-64https://repo.anaconda.com/pkgs/main/noarchhttps://repo.anaconda.com/pkgs/free/linux-64https://repo.anaconda.com/pkgs/free/noarchhttps://repo.anaconda.com/pkgs/r/linux-64https://repo.anaconda.com/pkgs/r/noarchhttps://repo.anaconda.com/pkgs/pro/linux-64https://repo.anaconda.com/pkgs/pro/noarchpackage cache : /home/anaconda3/pkgs/root/.conda/pkgsenvs directories : /home/anaconda3/envs/root/.conda/envsplatform : linux-64user-agent : conda/4.5.11 requests/2.19.1 CPython/3.7.0 Linux/3.10.0-327.el7.x86_64 centos/7 glibc/2.17UID:GID : 0:0netrc file : Noneoffline mode : False

2.Python虚拟环境

1) 创建环境

conda create -n your_env_name python=x.x

conda create -n Python38 python=3.8

在envs目录下有新创建的目录

(base) [root@oracledb Python38]# pwd
/home/anaconda3/envs/Python38

2)激活环境

(base) [root@oracledb anaconda3]# conda activate Python38  
(Python38) [root@oracledb anaconda3]# 
(Python38) [root@oracledb anaconda3]# python -V
Python 3.8.13
(Python38) [root@oracledb anaconda3]# 

3）退出环境

conda deactivate退出当前环境到base
source deactivate退出到root

(Python38) [root@oracledb anaconda3]# conda deactivate
(base) [root@oracledb anaconda3]# 
(base) [root@oracledb envs]# source deactivate
[root@oracledb envs]# 

4）删除环境

 conda remove -n Python38 --all

5）配置通道

查找一个包是否能够安装

conda search beautifulsoup4

如果速度比较慢，可以更换镜像源，添加Anaconda的TUNA镜像

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

channel URLs 中已经有新增的通道

[root@oracledb envs]# conda infoactive environment : Noneshell level : 0user config file : /root/.condarcpopulated config files : /root/.condarcconda version : 4.5.11conda-build version : 3.15.1python version : 3.7.0.final.0base environment : /home/anaconda3  (writable)channel URLs : https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/noarchhttps://repo.anaconda.com/pkgs/main/linux-64https://repo.anaconda.com/pkgs/main/noarchhttps://repo.anaconda.com/pkgs/free/linux-64https://repo.anaconda.com/pkgs/free/noarchhttps://repo.anaconda.com/pkgs/r/linux-64https://repo.anaconda.com/pkgs/r/noarchhttps://repo.anaconda.com/pkgs/pro/linux-64https://repo.anaconda.com/pkgs/pro/noarchpackage cache : /home/anaconda3/pkgs/root/.conda/pkgsenvs directories : /home/anaconda3/envs/root/.conda/envsplatform : linux-64user-agent : conda/4.5.11 requests/2.19.1 CPython/3.7.0 Linux/3.10.0-327.el7.x86_64 centos/7 glibc/2.17UID:GID : 0:0netrc file : Noneoffline mode : False[root@oracledb envs]# 

恢复默认镜像通道，删除新增的TUNA镜像

conda config --remove-key channels

6）帮助

conda env -h

[root@oracledb envs]# conda env -h
