Actual procedure

$ sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev python-openssl git

It is said that you should look at https://github.com/pyenv/pyenv/wiki/Common-build-problems, so solve it with the following command described here. Believe in the comment and chanting. I don't understand the contents at all, but it will install what you need.

Python installation failed again. It is said that there is no zlib, so install it

sudo apt-get install zlib1g-dev

Installation failed. It takes a lot of time, but it hurts to fail after all.

WARNING: The Python bz2 extension was not compiled. Missing the bzip2 lib?

So I installed bzip2 lib individually.

Then it worked.

Installed Python-3.7.4

There is no sense of accomplishment when I see it.

from now on

I worked and wrote so far with the tension that seems to have reached the goal, The goal is to create something using the API, so I've only finally arrived at the start.

In addition, it is necessary to be enthusiastic and face each other.
