如何在Travis CI上构建Python 3.8？

Question

例如，当我按照提供的说明在Travis上构建Python 3.8时，使用

language: python 

matrix:
  include:
    - name: "Python 3.8 dev"
      python: 3.8-dev
      dist: trusty
      env: PYTHON=python3 PIP=pip3  # Unnecessary on Lunix

我懂了

3.8-dev is not installed; attempting download

将dist更改为xenial，这是3.7或更高版本所必需的。
