Maybe you don't need `pyenv` and/or `virtualenv` in most cases.
|
||
|
|
|
||
|
|
## Install Python
|
||
|
|
|
||
|
|
> Don't have `brew`? Go to <https://brew.sh>.
|
||
|
|
|
||
|
|
```
|
||
|
|
brew install python3
|
||
|
|
```
|
||
|
|
|
||
|
|
If you still need Python 2, run `brew install python`.
|
||
|
|
|
||
|
|
## Install Jupyter Notebook
|
||
|
|
|
||
|
|
```
|
||
|
|
pip3 install jupyter
|
||
|
|
python3 -m ipykernel install --user
|
||
|
|
```
|
||
|
|
|
||
|
|
You also want Python 2 kernel, so then:
|
||
|
|
|
||
|
|
```
|
||
|
|
pip install ipykernel
|
||
|
|
python -m ipykernel install --user
|
||
|
|
```
|
||
|
|
|
||
|
|
That's all.
|
||
|
|
|
||
|
|
# How about `virtualenv`?
|
||
|
|
|
||
|
|
Since Python 3 got its own virtual environment tool called [venv](https://docs.python.org/3/library/venv.html), You no longer need `virtualenv` itself.
|
||
|
|
|
||
|
|
If you want a virtual envs on your project, run:
|
||
|
|
|
||
|
|
```
|
||
|
|
python3 -m venv venv
|
||
|
|
source ./venv/bin/activate
|
||
|
|
```
|
||
|
|
|
||
|
|
then `venv` will creates virtual envs on __./venv__ folder on the root of your project.
