Conda 创建和删除虚拟环境
- 2021 年 10 月 14 日
- 笔记
1、检验当前conda的版本 conda -V
C:\Users>conda -V
conda 4.10.1
2、conda 常用的命令
- 查看已有的虚拟环境
C:\Users>conda env list
# conda environments:
#
base * D:\APP\Anaconda3
clone D:\APP\Anaconda3\envs\clone
king D:\APP\Anaconda3\envs\king
opencv D:\APP\Anaconda3\envs\opencv
- 创建虚拟环境 conda create -n env_name python=x.y
C:\Users>conda create -n json python=3.7
Collecting package metadata (current_repodata.json): done
Solving environment: done
==> WARNING: A newer version of conda exists. <==
current version: 4.10.1
latest version: 4.10.3
Please update conda by running
$ conda update -n base -c defaults conda

这下载速度，我想吐槽了，是真的慢呀。不知道是不是我网速问题(⊙︿⊙)
- 删除虚拟环境 conda remove -n env_name –all
C:\Users>conda remove -n king --all

-
安装指定环境下某个package
conda install -n env_name [package] -
删除指定环境下某个package
conda remove -n env_name [package] -
更新指定环境下某个package
conda update -n env_name [package]
若已经进入某个环境中，需要操作以上操作，直接省略-n env_name即可。
3、其它
安装完anaconda后，发现每次打开中断后都会自动进入到base的虚拟环境中去。可以只有conda deactivate退出，野结衣关闭自动打开的虚拟环境，命令如下：
conda config –set auto_activate_base false
