最近在弄机器学习，需要安装tensorflow这个库，于是按照tensorflow中文教程安装，结果很不顺利。接下来就把遇到的问题给大家说一下，并说明解决方案。
1、安装官网安装方法，我在mac环境下安装总会抱这个错，

raise ReadTimeoutError(self._pool, None, 'Read timed out.')
ReadTimeoutError: HTTPSConnectionPool(host='storage.googleapis.com', port=443): Read timed out.
我以为是网络问题，结果经过各方考证，不是这个原因。由于国内镜像原因，在加上天朝，这个你懂的。我就不说明了。
在机器学习群请教大佬后，放弃线上安装方法，通过Python官网库的安装方法。将安装包下载下来进行安装。
sudo pip install tensorflow路径 （sudo pip install /xxx/xxx/xxx/tensorflow-1.4.1-cp27-cp27m-macosx_10_11_x86_64.whl）
一路很顺畅，正在高兴的时候，突然又显红了。
报错如下

DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

该提示告诉我们numpy版本问题，告诉我先删除现有版本，再安装支持tensorflow的版本，按照指示，sudo pip uninstall numpy 结果提示我权限不够。
The directory '/Users/bene/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

无解。
只有另寻出路。
从新单独更新numpy库，不理会现有的版本 ：sudo pip install numpy --upgrade --ignore-installed
成功！！！！
再重新安装一下：
