安装 tensorflow 时遇到 OSError: [Errno 1] Operation not permitted 的解决办法

Installing collected packages: numpy, scipy, six, pyyaml, Keras, opencv-python, h5py, html5lib, bleach, futures, wheel, werkzeug, markdown, protobuf, tensorflow-tensorboard, pbr, funcsigs, mock, backports.weakref, tensorflow
  Found existing installation: numpy 1.14.1
    Uninstalling numpy-1.14.1:
      Successfully uninstalled numpy-1.14.1
  Found existing installation: scipy 0.13.0b1
    DEPRECATION: Uninstalling a distutils installed project (scipy) 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.
    Uninstalling scipy-0.13.0b1:

首先我想到的是目录权限的问题，于是一通的修改 不知道执行了多少次的 ```chmod 755``` 结果没有任何卵用；

那是不是因为 目录归属有问题呢？ 又是一通修改 ```chown usename``` 结果还是没有用；

最后只好谷歌了，搜到这篇文章：https://www.jianshu.com/p/7a18c78b5982， yes 他解决了我的问题，只需要小小的升级下旧的包就可以搞定了，这里把执行的命令记录如下：

$ pip install --upgrade pip

$ sudo pip install numpy --upgrade --ignore-installed
$ sudo pip install scipy --upgrade --ignore-installed
$ sudo pip install scikit-learn --upgrade --ignore-installed
