如何在travis上使用osx环境构建python项目

Question

我正在尝试为Travis上的项目构建osx支持.问题是osx本身不发布python virtualenv.这是问题所在.我已经解决了这个问题并相应地修改了我的travis文件.我的构建仍然失败了osx.这是一个travis构建链接.这是我的travis.yml文件

language: python
matrix:
    include:
        # Use the built in venv for linux builds
        - os: linux
          sudo: required
          python: "2.7"
          dist: trusty

        - os: linux
          sudo: required
          python: "3.5"
          dist: trusty

        - os: linux
          sudo: required
          python: "3.6"
          dist: trusty

        # Use generic language for osx
        - os: osx
          language: generic
          python: "2.7"

        - os: osx
          language: generic
          python: "3.5"

        - os: osx
          language: generic
          python: "3.6"

before_install:
 - .travis/before_install.sh
 - mkdir $HOME/data
 - echo $PWD
 - cd $HOME/data && wget ftp://ftp.astron.nl/outgoing/Measures/WSRT_Measures.ztar && tar xf WSRT_Measures.ztar && cd -
 - echo $PWD
install:
 - export PATH="$HOME/miniconda/bin:$PATH"
 - source activate testenv
 - export CPATH="$HOME/miniconda/envs/testenv/include:$CPATH"
 - echo $CPATH
 - python setup.py develop
 - pip install -r tests/requirements.txt
 - pip install coveralls travis-sphinx
script:
 - nosetests --with-coverage
 - travis-sphinx --nowarn -s doc build

这是我的before_install.sh文件.

set -e
set -v

if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then brew update; fi
if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then 
    if [[ "$TRAVIS_PYTHON_VERSION" == "2.7" ]]; then
        brew install python;
        virtualenv venv -p python;
        source venv/bin/activate;
    else
        brew install python3;
        virtualenv venv -p python3;
        source venv/bin/activate;
    fi
fi


if [ "$TRAVIS_OS_NAME" = linux ]; then
    sudo apt-get update
    MINICONDAVERSION="Linux"
else
    MINICONDAVERSION="MacOSX"
fi

if [[ "$TRAVIS_PYTHON_VERSION" == "2.7" ]]; then
  wget https://repo.continuum.io/miniconda/Miniconda2-latest-$MINICONDAVERSION-x86_64.sh -O miniconda.sh;
else
  wget https://repo.continuum.io/miniconda/Miniconda3-latest-$MINICONDAVERSION-x86_64.sh -O miniconda.sh;
  fi

bash miniconda.sh -b -p $HOME/miniconda
export PATH="$HOME/miniconda/bin:$PATH"
hash -r
conda config --set always_yes yes --set changeps1 no
conda update -q conda
conda config --add channels conda-forge
# Useful for debugging any issues with conda
conda info -a
which python
conda create -q -n testenv python=$TRAVIS_PYTHON_VERSION casacore=2.3.0

echo "measures.directory: /home/travis/data" > $HOME/.casarc

当我尝试构建conda环境时,它会指出以下错误.

CondaValueError: invalid package specification: python=

就像评论中推荐的 @randomir 一样，
查看在 OSX 上运行 python 的 Travis 文档
，并确保定义了你的TRAVIS_PYTHON_VERSION
