Initialize Anaconda

1. List environments ---------------

$ conda env list

1. Create environment with preinstalled packages ---------------

$ conda create -n my_env numpy  #create my_env, install numpy
$ conda create -n py2 python=2  #create py2, install python ver.=2
$ conda create -n py3 python=3  #create py3, install python ver.=3
$ conda env list 
base               *    /Users/RAYMOND/anaconda3
my_env                  /Users/RAYMOND/anaconda3/envs/my_env
py2                     /Users/RAYMOND/anaconda3/envs/py2
py3                     /Users/RAYMOND/anaconda3/envs/py3
                       /Users/RAYMOND/miniconda3       
 
# Enter environment ---------------
# * indicates which environment we are using
$ source activate py2
(py2) $ conda env list
base                    /Users/RAYMOND/anaconda3
my_env                  /Users/RAYMOND/anaconda3/envs/my_env
py2                *    /Users/RAYMOND/anaconda3/envs/py2
py3                     /Users/RAYMOND/anaconda3/envs/py3
                       /Users/RAYMOND/miniconda3

1. Exit environment ---------------

(py2) $ source deactivate

1. Delete environment ---------------

$ conda env remove -n my_env
$ conda env remove -n py2
$ conda env remove -n py3
$ conda env list
base               *    /Users/RAYMOND/anaconda3

管理套件

進入一個環境後，在開發過程中我們可能會發現有一些套件還需要安裝，可以採用以下的指令管理套件

   安裝套件 conda install pkg_name1 pkg_name2 ...
   安裝套件指定版本 conda install pkg_name=version_number
   移除套件 conda remove pkg_name
   更新套件 conda update pkg_name
   更新所有套件 conda update -all
   列出所有已安裝套件 conda list
   清除安裝後下載的原始檔 conda clean -tp
   找尋套件 conda search pkg_name

1. Install package ---------------

conda install numpy conda install numpy scipy pandas

1. Install package with specific version number ---------------

conda install numpy=1.10

1. Remove package ---------------

conda remove package_name

1. Update package ---------------

conda update package_name

1. Update all package ---------------

conda update --all

1. List installed packages ---------------

conda list

1. Clean up downloaded library ---------------

$ conda clean -tp

1. Search package ---------------

conda search package_name
