Anaconda3.6 下分别配置py2.7和py3.5环境

下载并安装Anoconda3.6

https://www.anaconda.com/download/#linux

• terminal 直接 bash Anaconda3-5.2.0-Linux-x86_64.sh 即可
• 注意过程enter : yes or no

检验安装效果

• 输入： conda -V
• 输出：

conda 4.5.4

到此，证明anaconda安装好了。如果有问题，百度配置以下即可。

基于 python3.5 创建一个名为py3 的环境

conda create --name py3 python=3.5

• terminal输出：

到这里基本搞定。

• 切换环境测试：

source activate py2
(py2) veyron@veyron-pc:~$ python

配置 Pycharm

File | Settings | Project: mclearning | Project Interpreter | Show
All… 然后进入 Add Python Interpreter，先选左侧Conda Environment ，然后勾选 Existing environment，选择之前配好的py环境
比如需要配置py2.7就 /home/veyron/anaconda3/envs/py2/bin/python
比如需要配置py2.7就 /home/veyron/anaconda3/envs/py3/bin/python

这样就搞定。
