ipython notebook 安装及设置的一些后续问题

官方安装指南

https://github.com/yyuu/pyenv#homebrew-on-mac-os-x

注意：

Rebuild the shim binaries. You should do this any time you install a new Python binary. (Examples: installing a new Python version, or installing a package that provides a binary.)

看完视频可以参考教程

http://seisman.info/python-pyenv.html

视频后半部分是设置virtual environment，可以参考如下教程后面的指南设置，此时我的电脑尚没有设置

http://amaral-lab.org/resources/guides/pyenv-tutorial

pyenv version                         #显示当前使用的Python 

pyenv which python                 #显示当前Python的安裝路径 

pyenv global <version>             #设置默认的Python版本 

pyenv local <version>             #在当前路径创建一个.python-version，以后进入这个目录自动切换为该版本 

pyenv shell <version>             #在当前shell的session中启用某个Python版本，优先级高于global,local 

下面这个网页也有一些语句的说明

计划以后补装python3

上面提到了如何装，但是不详细

这里有更多详细如何用notebook的指南

官方指南kernel for both python 2 and 3

https://ipython.readthedocs.org/en/latest/install/kernel_install.html

 但是按照指示写了如下的代码以后

conda create -n ipykernel_py2 python=2 ipykernel
source activate ipykernel_py2    # On Windows, remove the word 'source'
python -m ipykernel install --user

再用ipython notebook 或者jupyter notebook 会报错，于是把env中建的ipykernel_py3文件夹移走，这时ipython notebook可以正常使用了，new下拉框中出现了python3 的选项，但是会显示kernel error，不知道这个问题如何解决？
