I try to update pyenv installation list. I know update list is running cd /opt/circleci/.pyenv; git pull, but install 3.9.0 is failed. How to fix it?

  deploy-dev:
    machine: true
    steps:
      - checkout
      - run:
          name: load latest
          command: |
            cd /opt/circleci/.pyenv
            git pull
      - run:
          name: install python 3.9.0
          command: |
            pyenv install 3.9.0
            pyenv global 3.9.0

#!/bin/bash -eo pipefail
pyenv install 3.9.0
pyenv global 3.9.0
