BUG: "pyenv: version `3.8.1' is not installed (set by /workspace/flask-rest-hello/.python-version)"

[jferragut]

Description:
Upon starting a fresh container, you see the output below.

gitpod /workspace/flask-rest-hello $  HISTFILE=/workspace/.gitpod/cmd-0 history -r; {
> cp .env.example .env;
> pipenv install;
> mysql -u root -e "CREATE DATABASE example";
> pipenv run init;
> pipenv run migrate;
> pipenv run upgrade;
> 
> } && {
> pipenv run start;
> 
> }
pyenv: version `3.8.1' is not installed (set by /workspace/flask-rest-hello/.python-version)
pyenv: version `3.8.1' is not installed (set by /workspace/flask-rest-hello/.python-version)
pyenv: version `3.8.1' is not installed (set by /workspace/flask-rest-hello/.python-version)
pyenv: version `3.8.1' is not installed (set by /workspace/flask-rest-hello/.python-version)
gitpod /workspace/flask-rest-hello $ 

Expectation:
The boilerplate should open a port and run server when it starts

Resolution:
To resolve this issue, I ran the following commands

pyenv install 3.8.1
python -m pip install pipenv
pipenv install flask
pipenv run start

My guess is that their may be something wrong with the gitpod config.
