To setup pynecone on my Mac

This experience can also use in Windows & Ubuntu too.

Install n command and use it to setup NodeJS 12.22

Setup NodeJS environment for pynecone first time.

(1) Install NodeJS 12.22 environment
$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
$ which npm

In this version of npm, you can install "n".
And then you can manage many versions of NodeJS easily. 

$ sudo npm install -g n

In the following, we can 
install by NodeJS 12.22 by n. 

$ sudo n 12.22

Right now, you are setup NodeJS 12.22 ready for pynecone development. For more information, if you would like to understand more about using n to do environment managment, then the following section is for you.

Some command example to manage NodeJS by n

When your NodeJS development environment get dirty after doing many
npm install, you can delete it and create new one again.
list all NodeJS environment we have, right now
$ n ls

node/8.12.0
node/10.13.0
node/12.0.0
node/12.22.12
node/13.0.0
node/14.0.0

Select from the list, So you can go what version you want
$ sudo n
Using keyboard up/down to select node/12.0.0 environment

Delete some NodeJS environment for specific version
$ sudo n rm 12.22.12
$ n ls

node/8.12.0
node/10.13.0
node/12.0.0
node/13.0.0
node/14.0.0

Create new nodejs environment for specific version
$ sudo n 12.22
$ n ls

node/8.12.0
node/10.13.0
node/12.0.0
node/12.22.12
node/13.0.0
node/14.0.0

Setup by pynecone conda

Download and install anaconda first.
https://www.anaconda.com/products/distribution

After installing finished, you need to ensure you
have the conda command. We can check it by which 
command in Ubuntu & Mac  

$ which conda

To create virtual envionment with python 3.11 
and its name is pynecoen-311

$ conda create -n pynecone-311 python=3.11

Jump into the virtual environment pynecone-311

$ conda activate pynecone-311

Install pynecone by pip in the pynecone-311

$ pip install pynecone

If you want to leave pynecone-311 environment
$ conda deactivate

Some command example to use conda

Show how many environments you have and where you are staying now.
$ conda env list

# conda environments:
#
base                  *  /Users/milochen/opt/anaconda3
mqtt-pynecone-311        /Users/milochen/opt/anaconda3/envs/mqtt-pynecone-311
pynecone-311             /Users/milochen/opt/anaconda3/envs/pynecone-311

$ conda activate pynecone-311
$ conda env list

# conda environments:
#
base                     /Users/milochen/opt/anaconda3
mqtt-pynecone-311        /Users/milochen/opt/anaconda3/envs/mqtt-pynecone-311
pynecone-311          *  /Users/milochen/opt/anaconda3/envs/pynecone-311

Right now, you know how to switch environment.

You can leave your pynecone environment.
Then delete it and create it again.
Leave
$ conda deactivate

Delete
$ conda remove -n pynecone-311 –all

Create
$ conda create -n pynecone-311 python=3.11

Enter
$ conda activate pynecone-311

Setup pynecone
$ pip install pynecone

Create pynecone project and run it
$ mkdir my_app_name
$ cd my_app_name
$ pc init
$ pc run
