conda配置python混合开发环境一站式入门【全平台】

下载安装

• 清华的镜像 [https://mirror.tuna.tsinghua.edu.cn/help/anaconda/]
• 官方说明 [http://conda.pydata.org/docs/using/envs.html]

Windows

直接下载安装包，下载完，直接下一步默认安装就好。

Linux or Mac

直接下载脚本，然后直接sh xxxx.sh安装就ok了

基本命令

＃查看版本
conda info —envs
或
conda env list

＃ 安装完整版python2版本的conda
conda create -n py2 python=2 anaconda

＃ 移除虚拟环境
conda remove --all -n 3todo

# 创建只有django的python2环境，名字py2-dj，注意，python=2 django是连续参数
conda create python=2 django -n py2-dj

＃ 如果不指定python版本,那是不能够滴，会报错
conda create -n env-test
Error: too few arguments, must supply command line package specs or --file

# 所以要至少指定个pytohn版本，可以不带任何库
conda create -n env-test python=3

自定义命令别名

下面是我自己编的，你可以自定义。然后放到.bashrc,或.bash_profile就可以了！

linux或mac

# alias for conda
 alias cl="conda env list"
 alias cc="conda create -n"
 alias coa="source activate"
 alias cod="source deactivate"
 alias cr="conda remove --all -n"

注意：对于Linux，最好自己添加一下环境变量，conda的脚本执行完，也会提醒你的。

添加下面这行到.bashrc，

export PATH=/root/anaconda3/bin:$PATH

最后别忘了重新加载一下。

source ~/.bashrc

Windows最好配合ConEmu使用

在settings->Startup>Environment

alias cl=conda env list
alias cc=conda create -n $*
alias coa=activate $*
alias cod=deactivate
alias cr=conda remove --all -n $*

在mac中的使用示例
