Mac Anaconda中安装TensorFlow，解决新环境spyder打不开的问题

看了很多教程，走了很多弯路，Anaconda卸了重装，终于搞好了，分享一下自己的做法。

1、安装Anaconda

此步省略介绍

2、创建新环境

// 创建环境
conda create -n tensorflow python=3.6

3、安装tensorflow

// 激活环境
source activate tensorflow
// 安装Tensorflow
python -m pip install tensorflow -i https://pypi.douban.com/simple

按照上述操作后，spyder打不开了，报错：

Traceback (most recent call last):
  File "/Users/qiaoyiran/anaconda3/bin/spyder", line 4, in 
    import spyder.app.start
  File "/Users/qiaoyiran/anaconda3/lib/python3.6/site-packages/spyder/app/start.py", line 22, in

解决办法在github上面找到了解决方法，需要

4、遂在新建的环境中试用，报错说没有这个包，于是先install 再update，之后再install spyder ，成功！

//install
conda install python.app

//update
conda update python.app
