brew安裝anaconda3
brew cask install anaconda3
安裝之后打開路徑查看：/usr/local/anaconda3/bin
anaconda3環境變量設置
vim ~/.zshrc
export PATH=/usr/local/anaconda3/bin:$PATH
source ~/.zshrc
驗證
conda --version
# 看到版本好就成功了
安裝雙版本
conda create --name python2 python=2.7
conda create --name python3 python=3.7
查看目錄 /usr/local/anaconda3/envs/
命令后切換python環境
# 查看本地的py環境
➜ ~ conda info -e
# conda environments:
#
base * /usr/local/anaconda3
python2 /usr/local/anaconda3/envs/python2
python27 /usr/local/anaconda3/envs/python27
python3 /usr/local/anaconda3/envs/python3
# 進入py版本
➜ ~ source activate python27
(python27) ➜ ~
# 退出py版本
conda deactivate
pip
進入py版本之后，有時候不知道pip把安裝包安裝到哪里了，用這個方法很好使：
(python27) ➜ ~ python

>>> import requests
>>> requests
<module 'requests' from '/usr/local/anaconda3/envs/python27/lib/python2.7/site-packages/requests/__init__.pyc'>
/usr/local/anaconda3/envs/python27/lib/python2.7/site-packages/requests/ 就是了。
