为什么Conda激活环境后无法调用正确的Python版本? [英] Why Conda cannot call correct Python version after activating the environment?

问题描述

我在Linux下具有以下conda环境:

I have the following conda environment under Linux:

$ conda info -e
# conda environments:
#
py33                     /u21/coyotito/.anaconda/envs/py33
root                  *  /u21/coyotito/.anaconda

然后使用以下命令创建py33:

And py33 is created with this command:

$ conda create -n py33 python=3.3 anaconda

问题是，当我激活py33时，它仍然无法调用Python版本3.3.

The problem is when I activate py33 it still cannot call Python version 3.3.

[coyotito@pearl ~]$ source activate py33
(coyotito)[coyotito@pearl ~]$ python --version
Python 2.7.10 :: Anaconda 2.1.0 (64-bit)
(coyotito)[coyotito@pearl ~]$ conda info -e
# conda environments:
#
py33                     /u21/coyotito/.anaconda/envs/py33
root                  *  /u21/coyotito/.anaconda

也就是说，它仍在调用旧的python.另请注意，括号下的提示不是(py33).

Namely it still calling old python. Notice also that the prompt under bracket is not (py33).

(coyotito)[coyotito@pearl ~]$ which python
~/.anaconda/bin/python

在新环境中代替python:

Instead of python in new environment:

~/.anaconda/envs/py33/bin/python3.3

如何解决此问题?

更新

我在~/.bash_profile中的PATH环境如下:

My PATH environment in ~/.bash_profile looks like this:

export PATH=$HOME/.anaconda/bin:$PATH

推荐答案

我遇到了完全相同的问题.不知道我是如何陷入困境的，但是我用一个简单的方法解决了这个问题:

I had the exact same problem. Not sure what I did to get into that mess, but I solved it with a simple:

conda deactivate
conda activate foo_env
