在 Mac OS X 10.8.4 上使用 homebrew 和 pip 安装 VirtualEnv

Question

当我使用 homebrew + pip 安装 virtualenv 时，我收到以下警告：

$ sudo pip install virtualenv
Downloading/unpacking virtualenv
  Downloading virtualenv-1.10.1.tar.gz (1.3MB): 1.3MB downloaded
  Running setup.py egg_info for package virtualenv

    warning: no files found matching '*.egg' under directory 'virtualenv_support'
    warning: no previously-included files matching '*' found under directory 'docs/_templates'
    warning: no previously-included files matching '*' found under directory 'docs/_build'
Installing collected packages: virtualenv
  Running setup.py install for virtualenv

    warning: no files found matching '*.egg' under directory 'virtualenv_support'
    warning: no previously-included files matching '*' found under directory 'docs/_templates'
    warning: no previously-included files matching '*' found under directory 'docs/_build'
    Installing virtualenv script to /usr/local/bin
    Installing virtualenv-2.7 script to /usr/local/bin
Successfully installed virtualenv
Cleaning up...

似乎 virtualenv 已安装并正在工作（virtualenv 命令有效等） 但是这些警告是什么意思？ virtualenv_support 到底是什么？我应该担心他们吗？

Answer 1

这是安装 virtualenv 时出现的来自 Python 的 setuptools 的警告；在 Homebrew 之外安装时也会发生这种情况。这实际上不是问题。
