MiniCoda安装步骤及问题

众所周知，python是世界上最好的两门语言。

conda用于python项目做多版本环境创建与切换的

有效的进行版本之间的隔离

1、下载安装文件

• For Mac OS

  cd ~
  wget https://repo.continuum.io/miniconda/miniconda3-latest-MacOSX-x86_64.sh
  

• For Linux

  cd ~
  wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
  

2、安装

• For MacOSX

cd ~
bash miniconda3-latest-MacOSX-x86_64.sh
# 根据提示完成安装

• For Linux

cd ~
bash Miniconda3-latest-Linux-x86_64.sh
# 根据提示完成安装

3、手动生效环境变量

source ~/.bash_profile

4、验证安装成功

conda -h

# 出现如下信息表示成功

usage: conda [-h] [-V] command ...

conda is a tool for managing and deploying applications, environments and packages.

Options:

...

5、升级conda以及pip version

conda upgrade conda
pip install --upgrade pip

6、查看env list

conda-env list

# conda environments:
#
base                  *  /Users/chenpeng/miniconda3

7、创建虚拟环境

创建一个名叫pj_odoo12的py3.6环境

conda create -n pj_odoo12 python=3.6 -y
conda create -n py38 python=3.8 -y

• 创建完毕提示

# To activate this environment, use
#
#     $ conda activate pj_odoo12
#
# To deactivate an active environment, use
#
#     $ conda deactivate

• 虚拟环境地址

# environment location: /Users/chenpeng/miniconda3/envs/pj_odoo12

/Users/xxxx/miniconda3/envs/pj_odoo12

8、激活和退出虚拟环境

# 激活
conda activate py38

# 退出
conda deactivate

9、卸载miniconda

• 去掉~/.bash_profile环境变量配置
• 删除miniconda目录
• 删除隐藏的配置文件

# 删除相关的环境变量配置  不是添加是删除哦!!!!!
# export PATH="/Users/chenpeng/miniconda3/bin:$PATH"

# 删除miniconda
rm -rf ~/miniconda3

# 删除相关隐藏文件
rm -rf ~/.condarc
rm -rf ~/.conda
rm -rf ~/.continuum

10、常用命令

查看当前存在哪些虚拟环境

# 标记*的代表当前所处的虚拟环境
conda env list
conda info -e

创建python虚拟环境

conda create -n your_env_name python=X.X（2.7、3.6等)

激活虚拟环境

conda activate your_env_name

虚拟环境中安装额外的包

conda install -n your_env_name [package]

关闭虚拟环境

conda deactivate

删除虚拟环境

conda remove -n your_env_name(虚拟环境名称) --all

# or

conda env remove -n ENV_NAME

删除环境中的某个包

conda remove --name your_env_name  package_name

11、换源

1、Miniconda3及pip换源

清华源地址：https://mirrors.tuna.tsinghua.edu.cn/help/anaconda/

• 添加命令

# 清华大学
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --set show_channel_urls yes

# 中科大
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes

# 上海交大
conda config --add channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/cloud/conda-forge/
conda config --set show_channel_urls yes

• 删除命令

conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/


conda config --remove channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/pkgs/main/
conda config --remove channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/pkgs/free/
conda config --remove channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/cloud/conda-forge/

conda config --remove channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
conda config --remove channels https://mirrors.sjtug.sjtu.edu.cn/anaconda/pkgs/free/

• pip永久换源
• 修改或者添加~/.pip/pip.conf

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

12、注意事项

1、解决pyenv 和 conda 冲突

• 切换至系统的py环境

pyenv global system

2、关闭虚拟环境问题

source deactivate已经弃用

请使用conda deactivate

• 关闭遇到No such file or directory

DeprecationWarning: 'source deactivate' is deprecated. Use 'conda deactivate'.
