conda使用手册

conda介绍

conda是一个适用于多种语言的包、依赖项和环境管理系统(Python、R、Ruby、Lua、Scala、Java、JavaScript、C/C++、FORTRAN)
Conda 可以快速安装、运行和更新软件包及其依赖项。 Conda 可以轻松地在本地计算机上创建、保存、加载环境并在环境之间切换。 一开始是为 Python 程序创建的,但也可以打包和分发其他语言的软件。如果你需要一个需要不同版本Python的包,不需要切换到不同的环境管理器,因为conda也是一个环境管理器。 只需几个命令,您就可以设置一个完全独立的环境来运行不同版本的 Python,同时继续在正常环境中运行常用版本的 Python。
conda有Anaconda 和 Miniconda两个版本。
Miniconda 是 conda 的免费最小安装程序。 它是 Anaconda 的一个小型引导版本,仅包含 conda、Python、它们都依赖的包以及少量其他有用的包(例如 pip、zlib 等)。 如果需要更多软件包,需要使用 conda install 命令从 Anaconda 公共存储库或其他渠道(例如 conda-forge 或 bioconda)默认提供的数千个软件包中进行安装。

安装

These four commands quickly and quietly install the latest 64-bit version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for Linux, change the name of the .sh installer in the wget command.

mkdir -p ~/miniconda3
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
rm -rf ~/miniconda3/miniconda.sh

After installing, initialize your newly-installed Miniconda. The following commands initialize for bash and zsh shells:

~/miniconda3/bin/conda init bash
~/miniconda3/bin/conda init zsh

常用命令

conda env list

新建虚拟环境,如my_env

conda create -n my_env python=3.8

切换到想要的虚拟环境,如my_env

conda activate my_env

删除虚拟环境

conda env remove --name my_env

命令列表

conda is a tool for managing and deploying applications, environments and packages.
Options:
positional arguments:
command
clean Remove unused packages and caches.
config Modify configuration values in .condarc. This is modeled

file (/root/.condarc) by default.
create Create a new conda environment from a list of specified
packages.
help Displays a list of available conda commands and their help
strings.
info Display information about current conda install.
init Initialize conda for shell interaction. [Experimental]
install Installs a list of packages into a specified conda
environment.
list List linked packages in a conda environment.
package Low-level conda package utility. (EXPERIMENTAL)
remove Remove a list of packages from a specified conda environment.
uninstall Alias for conda remove.
run Run an executable in a conda environment. [Experimental]
search Search for packages and display associated information. The
input is a MatchSpec, a query language for conda packages.
See examples below.
update Updates conda packages to the latest compatible version.
upgrade Alias for conda update.
optional arguments:
-h, --help Show this help message and exit.
