python conda：创建了一个环境，但它没有使用conda的python

Question

我已经使用anaconda一段时间了，它的Python可执行文件位于/Users/ufo/opt/anaconda3/bin/Python。我尝试用conda创建一个环境，新环境将使用copy this Python to environment's bin。你知道吗

然而，对于当前的Anaconda versation，新环境将不会使用Anaconda的Python，而是使用Mac操作系统预装的原始Python，即python2.*。你知道吗

这里是一个检查anacondapython版本、创建/激活新环境以及再次检查的剪贴画。从snip中我注意到$PATH和Python版本的变化。你知道吗

如何在新环境中仍然使用anaconda的Python？你知道吗

Answer 1

一个简单的解决方法是在激活环境后将路径导出到所需的python。从下面的狙击手可以看出。你知道吗

export PATH=/Users/ufo/opt/anaconda3/bin/:$PATH

然后可以使用which python查看python的设置是否正确

使用python环境

export PATH=/Users/ufo/opt/anaconda3/envs/msg/bin/:$PATH
