无法使用 pip 在 MacOSX 上安装模拟包

Question

当我在 virtualenv 中执行 > pip install mock 时出现以下错误

(test)mystogans-mac:clean_arch resnet$ pip install --upgrade --force-reinstall mock
Downloading/unpacking mock
  Downloading mock-1.1.3.tar.gz (70kB): 70kB downloaded

    AttributeError: 'module' object has no attribute 'version'
    Complete output from command python setup.py egg_info:

setuptools_installed = StrictVersion(setuptools.version.__version__)

AttributeError: 'module' object has no attribute 'version'.

我在 travis 上遇到了同样的问题：https://travis-ci.org/bouncestorage/swiftproxy/builds/70313913。我通过升级 pip 和 setuptools 修复了它：

$ ./virtualenv/bin/pip install --upgrade pip
$ ./virtualenv/bin/pip install setuptools --no-use-wheel --upgrade

我使用 virtualenv，但如果没有，同样适用于你。
