如何在 travis 上使用 osx 环境构建 python 项目

Question

我正在尝试构建 osx 对 Travis 项目的支持。问题是 osx 不运送 python virtualenv 本机。 Here is the issue for that. I have gone through that issue and modified my travis file accordingly. Still my builds are failing with osx. Here 是一个 travis 构建 link。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环境时出现以下错误。

CondaValueError: invalid package specification: python=

喜欢评论里推荐的@randomir，
看看Travis docs running python on OSX
并确保定义 TRAVIS_PYTHON_VERSION
