如何更改 MAC cmd 中的默认 python3 路径？

Question

My Mac has contained multiple python versions so that I would like to fix one as my default python.

In the current, it has set the path of anaconda python. I have stopped to use the anaconda-python.

And I would like to change the python3 as default following with path:

/usr/local/bin/python3

How can I do this?

Hope:

• python3 as default that path

• jupyter notebook would follow that path

• pip3 install package would follow that path

Answer 1

您可以通过编辑 .bashrc 文件来更改此路径

export PATH="/usr/local/bin/python3:${PATH}"

Answer 2

Update your environment variable PATH to include your required python path. Append the python path in the beginning of the environment variable PATH, so that first it'll look in that path.

You need to update that in .bash_profile file. For that go to the root path and look for the mentioned file. Run ls-a to check whether the file is present.

cd ~
ls -a

Open the file

vi .bash_profile

Add below commands in the file (press i to go into insert mode)

# Setting PATH for Python
export PATH={ur path}:$PATH

(Save the file by pressing :wq)

Check whether the update is made by running

echo $PATH
