问题
I have two python installations..
python --> /Users/fraz/anaconda/bin/python (python2.7)
python3.7 --> /usr/local/bin/python3.7
Now.. I want reassign the commands. Such that
python points to python3.7 --> /usr/local/bin/python3.7
and python2 points to python2.7 /Users/fraz/anaconda/bin/python
How do i do this reassignment?
回答1:
follow this question, modify your ~/.bashrc, add a new line:
alias python=python3.7
save and exit then open terminal, type
source ~/.bashrc
in my machine, typing python2 will open python 2.x by default. but if needed, you can add a new alias
alias python2=python2.7
回答2:
you can use softlink
ln -s /usr/bin/python /usr/local/bin/python3.7
