Mac下安裝ipython3

安裝python3

brew install python3
## 此時，命令行輸入python3則打開python3，輸入python則打開python2

安裝ipython3

sudo pip install ipython
sudo pip3 install ipython ## ipython3 install

配置

安裝好以後，輸入ipython3命令發現沒有這個，所以進入到 /usr/local/bin 目錄
然後 vim ipython3 輸入如下內容，退出，chmod +x ipython3

#!/usr/local/opt/python/bin/python3.7
#-*- coding: utf-8 -*-
import re
import sys

from IPython import start_ipython
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(start_ipython())
###python3.7 目錄可以修改成你電腦實際ipython3的版本即可
