conda-[报错解决]-CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'

1.问题产生

刚拿到一台安装好conda 的机子，修改了.condarc里面的源之后，终于顺利快速的创建好了一个环境，但是执行conda activate my_env_01的时候出现了如下错误：

CommandNotFoundError: Your shell has not been properly configured to use ‘conda activate’.
To initialize your shell, run

$ conda init <SHELL_NAME>

Currently supported shells are:

See ‘conda init –help’ for more information and options.

IMPORTANT: You may need to close and restart your shell after running ‘conda init’.

2. 解决方法

依次执行下面这两条命令，然后就可以激活你的环境了。
source activate
source deactivate
conda activate my_env_01
