安装conda

通常安装minicoda即可

centos:

略

mac:

brew install miniconda

初始化环境

conda init <shell name>

创建环境2.7环境

conda create -n py27 python=2.7

如果上述安装2.7方式报如下错误,这是因为2.7版本官方已经停止维护了, conda默认channel检索不到python2.7

Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done

Current channels:

  - https://repo.anaconda.com/pkgs/main/osx-arm64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/osx-arm64
  - https://repo.anaconda.com/pkgs/r/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

指定渠道方式安装2.7环境

conda create -c 'https://repo.continuum.io/pkgs/free/osx-64' -n py27 python=2.7

进入环境

conda activate py27

退出环境

conda deactivate 

常用命令

# 查看环境
conda env --help    #查看帮助
conda env list     #列出所有的虚拟环境
conda list --name [虚拟环境名]    #查看指定虚拟环境下的package

#创建
conda create --name [虚拟环境名] [python的版本] [需要的包]
eg:
conda create --name myenv
conda create --name myenv python=2.7
conda create --name myenv pytohon=2.7 numpy scipy

#克隆
conda create --name [虚拟环境名] -- clone [colne的环境]
eg:
#创建一个和原python环境一样的虚拟环境
conda create --name mybase --clone base 

#删除
conda remove --name [虚拟环境名] -all

# 激活取消（默认的环境是base）
activate [虚拟环境名]
deactivate [虚拟环境名]
