travis-ci - Travis CI 突然失败 : conda command not found

Question

我的 travis-ci 构建中的 conda 环境从未出现过问题，但它突然开始失败。这是我的脚本

language: python - "2.7"

before_install:
    - wget http://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh -O miniconda.sh
    - chmod +x miniconda.sh
    - "./miniconda.sh -b"
    - export PATH=/home/travis/miniconda/bin:$PATH
    - conda update --yes conda
    - sudo rm -rf /dev/shm
    - sudo ln -s /run/shm /dev/shm
install:
    - conda install --yes python="2.7" psutil sphinx numpy scipy gdal cython h5py pycurl shapely mock matplotlib
    - pip install --user travis-sphinx

script:
    travis-sphinx build

after_success:
    travis-sphinx deploy

现在，当我的脚本尝试运行时，我在 miniconda 安装部分收到此错误

我不确定为什么构建突然无法更新 conda，有任何线索说明为什么会发生这种情况吗？

Answer 1

该问题是由 miniconda 的更改引起的。它现在安装在 ~/miniconda2 下，而不是 ~/miniconda 下。您只需将 travis.yml 文件的相应行更改为:

    - export PATH=/home/travis/miniconda2/bin:$PATH
