为什么我 conda 使用 python3.7 激活 env，但 python 版本仍然是 python3.5？

Question

I installed Miniconda3 on Ubuntu 16, and used the command

conda create -n py37 python=3.7

to create an env, and use command conda activate py37 to activate the env. But when I use command python --version to check my Python version, it show the version of Python is 3.5.2. So I try to create another env with Python 2.7, but after I activate this env, the version of Python is still 3.5.2.

Debugging

When I type type python , it shows python is aliased to '/usr/bin/python3.5.2' . Then by using the command to edit the .bashrc file, I found that there is a line of statement

alias python='/usr/bin/python3.5.2'

so I tried to change to

alias python='/home/vagrant/miniconda3/envs/django-judge/bin/python'

where the Python version of the env is 3.7. Then when I type type python again, it returns that python is aliased to '/home/vagrant/miniconda3/envs/django-judge/bin/python' . But now, under all envs, the Python version has become Python 3.7.

Answer 1

Remove the alias altogether: it is not compatible with Conda to alias python .
