Problem source

In MacOS, python is installed by default, and version 2.7

Python allows multiple python versions of the same system

Using the python command on the terminal opens python2.7 by default. To use python3, you need to use the python3 command. In order to use the python command directly to open python3, you need to set the alias alias.

problem

After configuring the environment variable in bash_profile, configure the alias alias

Cause problem: the alias will not take effect until bash_profile is executed on the terminal, and the command will expire every time iTerm2 is restarted

Source ~ / .bash_profile solution

Write the alias alias configuration in bash_profile in zshrc, which solves the problem of alias alias invalidation after iTerm2 restart

Vi ~ / .zshrc principle

In fact, this principle is equivalent to: only when the terminal executes bash_profile:source ~ / .bash_profile every time it is rebooted, the alias will take effect.

Because once iTerm2 is started, the zshrc file will be executed automatically

The configurations in zshrc are all global configurations

Be careful!

Note the version of shell used:

Zsh corresponds to zshrc.

Bash corresponds to basic.

When solving the problem of the failure of the alias alias restart terminal, the online solution is to add configuration in bashrc. I tried without success.

Later, I suddenly thought of the zshrc file that I used before.

It turns out that when I configured oh-my-zsh, I replaced the terminal shell from bash to zsh, which solved the problem perfectly after using zshrc.
