One of the most common headaches when working with Python is having to remember to use Python 3.x instead of Python 2.x. Luckily, it's really easy to setup Python 3 and pip 3 as the defaults. You first need to figure out where each one is installed using the `which` command:
|
|
|
|
```shell
|
|
which python3 # /usr/local/bin/python3
|
|
which pip3 # /usr/local/bin/pip3
|
|
```
|
|
|
|
Make a note of each response, so that you can add the paths as aliases to your shell environment's configuration file. Then, you can use `echo` to add a line for each one to either `.zshrc` or `.bashrc` depending on your environment:
|
|
|
|
```shell
|
|
# Linux or other bash environment
|
|
echo "alias python=/usr/local/bin/python3" >> ~/.bashrc
|
|
echo "alias pip=/usr/local/bin/pip3" >> ~/.bashrc
|
|
|
|
# Mac OS or other zsh environment
|
|
echo "alias python=/usr/local/bin/python3" >> ~/.zshrc
|
|
echo "alias pip=/usr/local/bin/pip3" >> ~/.zshrc
|
|
```
|
|
|
|
And you're all done! `python` and `pip` are both mapped to their 3.x versions,
