Anaconda和Brew的最佳做法 [英] Best Practices with Anaconda and Brew

问题描述

我刚刚获得了带有OSX Sierra的新Macbook，所以要确保正确设置我的开发环境.

I have just got a new Macbook with OSX Sierra, so want to ensure my development environment is setup properly.

我希望遵循此处提到的最佳做法": https://github.com/nicolashery/mac-dev-setup

I am looking to follow the 'best practices' mentioned here: https://github.com/nicolashery/mac-dev-setup

我需要Python 2.x进行工作(urllib，Pandas，Numpy，Scikit-learn)，并且需要Python 3.x进行一些在线课程(Pandas，Numpy，Django). 我已经分别使用brew install python和brew install python3安装了Python 2和3.

I need Python 2.x for work (urllib, Pandas, Numpy, Scikit-learn), and Python 3.x for some online classes (Pandas, Numpy, Django) I am taking. I have installed Python 2 and 3, using brew install python and brew install python3 respectively.

但是，在此链接上，没有提到Anaconda，只有IPython. 鉴于我已经通过Homebrew安装了Python 2和3，是否建议使用anaconda，还是应该坚持上面Github链接中提到的标准IPython? 阅读这篇文章后，我感到困惑: OS X-在anaconda之间进行选择和自制Python环境

However, on this link, there is no mention of Anaconda, just IPython. Given that I already have Python 2 and 3 installed via Homebrew, is it even advisable to use anaconda, or should I stick to standard IPython as mentioned on the Github link above? I am confused after reading this post: OS X - Deciding between anaconda and homebrew Python environments

如果Brew和Anaconda确实可以一起工作，我可以采取哪些具体步骤来确保两个版本之间没有冲突?

If Brew and Anaconda can indeed work together, what specific steps can I take to ensure that there are no conflicts between the two versions?

推荐答案

我是python的新手，并且在安装python时遇到了麻烦.我在Mac上同时安装了homebrew和anaconda的python.我的anaconda安装弄乱了我对vim和MacVim的自制python依赖性.

I am new to python, and have had trouble with my python installation. I have both python installation from homebrew and anaconda on my mac. My anaconda installation had messed up my homebrew python dependency for vim and MacVim.

我的解决方案是每当我通过自制软件安装/更新软件包时，都将从PATH中删除anaconda.这有点麻烦，但是我偶尔会通过自制软件安装/更新软件包，所以还可以.

My solution is whenever I am installing/update package via homebrew I would remove anaconda from my PATH. This is a bit of a pain, but I only installing/updating package via homebrew once in a while so it okay.

要在python 2和3之间切换，这是我在Terminal中的命令:

To switch between python 2 and 3 here are my commands in Terminal:

$ conda search python
...
...
$ conda install python=3.5.0

$ conda info -e
# conda environments:
#
py27                     /Users/apollotang/opt/local/anaconda2/envs/py27
py36                     /Users/apollotang/opt/local/anaconda2/envs/py36
root                  *  /Users/apollotang/opt/local/anaconda2

$ source activate py36      ### <——— here is the command in to change python version 
(py36) $ conda info -e
# conda environments:
#
py27                     /Users/apollotang/opt/local/anaconda2/envs/py27
py36                  *  /Users/apollotang/opt/local/anaconda2/envs/py36
root                     /Users/apollotang/opt/local/anaconda2

(py36) $ python -V
Python 3.6.2 :: Anaconda custom (x86_64)
