如何在 travis-ci 中构建 scikit-image？

Question

我正在尝试构建一个在 Travis-ci 上使用 scikit-image 的脚本。它抱怨 six 不是最新的。可以肯定的是，我尝试在 github 上复制 scikit-image 项目的 .travis.yml，但它并没有改变这种情况。我也试过更新six，但是没有用...

有人知道如何在 travis 上构建 scikit-image 吗？

我的requirements.txt:

# Requirements list:
scikit-image

我的踪迹：

$ source ~/virtualenv/python3.3/bin/activate

$ python --version

Python 3.3.5

$ pip --version

pip 6.0.7 from /home/travis/virtualenv/python3.3.5/lib/python3.3/site-packages (python 3.3)

5.80s$ pip install -r requirements.txt

You are using pip version 6.0.7, however version 6.0.8 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

Collecting scikit-image (from -r requirements.txt (line 2))

Answer 1

如果您收到未满足特定依赖项的错误，更具体地说明该依赖项通常会有所帮助。我喜欢把我不直接使用的依赖项放在 before_install 部分。

before_install:
    pip install six>=1.3
install:
    pip install -r requirements.txt

pip 允许您对安装的软件包版本指定限制。如果你必须使用 1.3，你可以使用 ==.
