基于ubuntu14.04 干净的系统一步步遇到的坑记录下来；
怀着平静学习的心情，问题总的能解决的！
1. 首先看了下当前python版本
python --version Python 2.7.6
2. 安装pip
先更新源
sudo apt-get update sudo apt-get upgrade
安装pip
sudo apt-get install python-pip
查看pip 版本
pip -V pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)
3. 尝试安装tensorflow，本以为安装就这么简单完成了：
tyler@pc:/opt/work/lazyzoon$ pip install tensorflow Downloading/unpacking tensorflow Could not find any downloads that satisfy the requirement tensorflow Cleaning up... No distributions at all found for tensorflow Storing debug log for failure in /home/tyler/.pip/pip.log
现在开始报错了
(1). 首先怀疑的是pip版本太低，想先升级pip版本
tyler@pc:/opt/work/lazyzoon$ pip install pip -U
Downloading/unpacking pip from https://files.pythonhosted.org/packages/d8/f3/413bab4ff08e1fc4828dfc59996d721917df8e8583ea85385d51125dceff/pip-19.0.3-py2.py3-none-any.whl#sha256=bd812612bbd8ba84159d9ddc0266b7fbce712fc9bc98c82dee5750546ec8ec64

没办法，只能换种方法升级pip，各种google,百度,找到下面这种方法升级成功
下载这个py脚本
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
然后执行
sudo python get-pip.py tyler@pc:/opt/work/lazyzoon$ sudo python get-pip.py DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

这样就安装成功了pip新版本
tyler@pc:/opt/work/lazyzoon$ pip -V pip 19.0.3 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
(2). 继续尝试安装tensorfolw,还是报错
sudo pip install tensorflow markdown 3.1 has requirement setuptools>=36, but you'll have setuptools 3.3 which is incompatible.

It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
然后发现我们本地还有python3 版本
tyler@pc:/opt/work/lazyzoon$ python3 -V Python 3.4.3
想着把python也用新版本
为了保险起见，我把之前用python2.7安装的pip卸载了

但是我发现我卸载的好像是1.5.4版本，可能这个尝试是多余。。
不管三七二十一了，用python3继续安装
tyler@pc:/opt/work/lazyzoon$ sudo python3 get-pip.py

这个错误是网络不稳定导致的，再次执行结果还是报错：

好像是six模块的问题，需要更新安装

继续尝试安装tensorflow,果然没让我失望，还是报错

看提示可能是需要安装 python-dev
那就安装呗，sudo apt-get install python-dev
安装成功了python-dev
回来继续安装numpy
结果，还是和上次一样的报错
思考了下，我现在用的pip3，对应的python也是python3了，应该要安装 sudo apt-get install python3-dev 才对，
安装 python3-dev，
sudo apt-get install python3-dev
安装成功后，继续执行
