python - 在自动化脚本中使用 Travis 设置中定义的变量

Question

我正在尝试将我的 codacy 令牌用作 Travis 变量，但 Travis 似乎并未读取该变量的值。下面是我的特拉维斯脚本：

branches:
  only: 
    - master

language: python
python:
  - "3.5"
  - "3.6"
  - "3.7"

env:
  - CODACY_PROJECT_TOKEN=${CodacyToken}
  
cache:
  - pip

# command to install dependencies
before_script:
  - sudo apt-get update
  - sudo apt-get install python3
  - sudo apt-get install python3-pip
  - sudo apt-get install python3-setuptools
  - pip3 install --upgrade setuptools
  - pip3 install -e .
  - pip3 install pytest-cov pytest
  - pip3 install codecov
  - pip3 install coveralls
  - pip3 install codacy-coverage
  - sudo apt-get update

# command to run tests
script:
  - pytest -vs -x --cov=./urlchecker tests/test_*.py

after_success:
  - codecov
  - coveralls
  - coverage xml
  - export CODACY_PROJECT_TOKEN=${CodacyToken}
  - python-codacy-coverage -r coverage.xml

我的CodacyToken变量在 travis/../settings 下定义：https ://travis-ci.com/github/urlstechie/urlchecker-python/settings

这导致：

2021-04-17 21:59:23,373 - 错误 - 环境变量 CODACY_PROJECT_TOKEN 未定义。知道我的语法是否有问题吗？
