conda acitvate激活失效： Your shell has not been properly configured to use ‘conda activate‘.

问题

在mac下的anaconda中创建了一个虚拟环境，想用 conda activate xxx 去激活，但是提示：

ommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run

    $ conda init 

Currently supported shells are:
  - bash
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

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

原因

原有的环境要退出，再重新激活

解决

重新进入旧环境：source activate
退出旧环境：conda deactivate
激活新环境：conda activate 新环境
