python-2.7 - Homebrew Python未安装setuptools

Question

这一切都在iMac OSX 10.9.2上

进行python2.7的Homebrew安装时，所有东西似乎都在正确创建。但是，在完成并尝试使用pip或easy_install进行任何操作后，我仍然收到以下错误:

$ pip install virtualenv
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

我尝试卸载并重新安装Brewed python，结果相同。我还使用-v运行了安装，生成了以下内容:

==> Verifying python-2.7.6.mavericks.bottle.tar.gz checksum
==> Pouring python-2.7.6.mavericks.bottle.tar.gz
tar xf /Library/Caches/Homebrew/python-2.7.6.mavericks.bottle.tar.gz
==> Caveats
Python demo
  /usr/local/share/python/Extras

Setuptools and Pip have been installed. To update them
  pip install --upgrade setuptools
  pip install --upgrade pip

You can install Python packages with (the outdated easy_install or)
  `pip install <your_favorite_package>`

They will install into the site-package directory
  /usr/local/lib/python2.7/site-packages

See: https://github.com/Homebrew/homebrew/wiki/Homebrew-and-Python

.app bundles were installed.
Run `brew linkapps` to symlink these to /Applications.

我注意到Homebrew Python页面指示“brew install python”应在“/usr/local/lib/python2.7/site-packages”处创建一个站点软件包文件夹。但是，当我导航到“/usr/local/lib”并使用“ls -a”时，没有与python相关的文件夹。

brew doctor 报告没有错误

预先谢谢您，并让我知道可能需要其他信息。

万一其他人遇到这个问题，我确实设法从以下页面中找到解决方案:

https://github.com/Homebrew/homebrew/issues/27515

显然，这是最新版本中的错误。做一个

brew install python --with-brewed-openssl

似乎可以解决问题。
