[LINUX] I raised the Python version from 2 to 3, but every time I restart the ubuntu terminal, the version remains 2.

Current status

I used pyenv to update python from 2 to 3.

After that, the Path was set with the following command.

$ export PATH="/home/{{user name}}/.pyenv/bin:$PATH"
$ eval "$(pyenv init -)"
$ eval "$(pyenv virtualenv-init -)"
$ python --version
Python 3.7.6

However, if I erase the terminal that is currently open and restart it,

$ python --version
Python 2.7.6

And the python version has returned to 2.

solution

** Edit /.bashrc to run commands automatically on reboot **

$ vi ~/.bashrc

Open the bashrc file and edit it.

In any place,

export PATH="/home/{{user name}}/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

If you add ok
