【问题描述】：
我刚刚报告了this issue upstream to IPython，但我相信如果我可以完全过滤掉该部分，那么 Buildout 中可能存在解决方法。
特拉维斯构建
在 Travis 上，相同的代码在 Python 3.5 上构建良好，但在 2.7 和 3.4 上失败。
What happens on Python 2.7 当我运行bin/buildout:
Installing ipython.
Getting distribution for 'ipython'.
error: Setup script exited with error in ipython setup command: Invalid environment marker: sys_platform == "win32" and python_version < "3.6"
An error occurred when trying to install /tmp/tmprLOC_8get_dist/ipython-5.3.0.tar.gz. Look above this message for any errors that were output by easy_install.
While:
Installing ipython.
Getting distribution for 'ipython'.
An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

在带有 Python 2.7.5 的 CentOS 7 上，它以下列方式失败：
[vagrant@devel vagrant]$ python --version
Python 2.7.5
[vagrant@devel vagrant]$ python bootstrap.py
ez_setup.py is deprecated and when using it setuptools will be pinned to 33.1.1 since it's the last version that supports setuptools self upgrade/installation, check https://github.com/pypa/setuptools/issues/581 for more info; use pip to install setuptools

We already have: setuptools 0.9.8

在带有 Python 3.4 的 CentOS 7 上，我没有遇到任何问题。

特拉维斯
- Python 2.7（失败）
- Python 3.4（失败）
- Python 3.5（成功）
本地
- Python 2.7.5（失败）
- Python 3.4.5（成功）
我的扩展配置有问题吗？有没有办法让我配置 Travis 在 bin/buildout 执行期间跳过给定部分？
