使用Virtualenv将Tensorflow安装到Python3

我正在尝试使用virtualenv将tensorflow安装到python3上，请遵循此网页上的说明。我正在使用MacSierra，Python 2.7和Python 3.5都在我的机器上。

使用此方法对python2.7效果良好，但对python3.5无效。以下是我发布的错误消息

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

任何帮助都将不胜感激。

用于virtualenv的解释器必须在创建时指定。在本例中，使用

virtualenv-p python3./tensorflow

指定python3作为该特定virtualenv的解释器
