AppVeyor上的工作服在某些构建中失败，但在另一些构建中失败。

Question

我试图让吡喃发布来自AppVeyor的报道报告。我添加了存储库的加密令牌，解释了这里。下面是appveyor.yml文件：

environment:
  COVERALLS_REPO_TOKEN:
    secure: 2NJ5Ct55cHJ9WEg3xbSqCuv0rdgzzb6pnzOIG5OkMbTndw3wOBrXntWFoQrXiMFi
    # this is pytest's token in coveralls.io, encrypted
    # using pytestbot account as detailed here:
    # https://www.appveyor.com/docs/build-configuration#secure-variables

install:
  - echo Installed Pythons
  - dir c:\Python*

  # install pypy using choco (redirect to a file and write to console in case
  # choco install returns non-zero, because choco install python.pypy is too
  # noisy)
  - choco install python.pypy > pypy-inst.log 2>&1 || (type pypy-inst.log & exit /b 1)
  - set PATH=C:\tools\pypy\pypy;%PATH% # so tox can find pypy
  - echo PyPy installed
  - pypy --version

  - C:\Python35\python -m pip install tox

build: false  # Not a C# project, build stuff at the test step instead.

test_script:
  # - C:\Python35\python -m tox  
  - C:\Python35\python -m tox -e coveralls  # coveralls is not in tox's envlist

奇怪的是，有些构建通过了，而另一些则没有。用于在按下上持续集成的GH面板显示，continuous-integration/appveyor/branch的构建按预期传递和发布覆盖范围，但continuous-integration/appveyor/pr构建失败，其中包含以下消息：

You have to provide either repo_token in .coveralls.yml, or launch via Travis or CircleCI
ERROR: InvocationError: 'C:\\projects\\pytest\\.tox\\coveralls\\Scripts\\coveralls.EXE' 

有人知道发生了什么事吗？

出于安全原因，在PR构建期间不设置安全变量。
