Mac下安装

• 官方安装方案: https://docs.conda.io/projects/miniconda/en/latest/

# 这种可能会出一些奇怪的问题
brew install miniconda
# 标准安装(注意这里选择 miniconda.sh 的版本)
# 1. install
mkdir -p ~/miniconda3
curl https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-x86_64.sh -o ~/miniconda3/miniconda.sh
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
rm -rf ~/miniconda3/miniconda.sh

# initial(bash运行第1条即可)
~/miniconda3/bin/conda init bash
~/miniconda3/bin/conda init zsh

# 注意，安装过程可能会产生 .bash_profile
# 可以将生成的内容 copy 到 .profile 里，即可
