终端开放时的Python怪异

当我打开终端时，我看到以下内容：

一切似乎都有效，但这很难看，可能会警告未来的麻烦。我在这台机器上安装了Python 2.7，然后将其删除为virtualenv以恢复2.6作为系统默认值。

有关如何调试此问题的任何想法？

编辑：

我的 .profile 打电话给 virtualenvwrapper.sh - 正如我所看到的那样，它位于下方 .../Versions/2.7 Python那么也许我应该在那里寻找问题？

来自评论：

检查你的 .bashrc 要么 .profile 对于Python特定的代码 - 如果你发现某些东西，确保它指向正确的版本，不管它 .../Versions/Current/...， .../Versions/2.7/...， 管他呢。
