CommandNotFoundError: Your shell has not been properly configured to use ‘conda activate‘.

问题

创建了一个新环境openne，退出mac终端后，再重新打开终端，想登陆新环境，出现错误提示。

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:
  - 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

必须先进入默认环境，再退出，再操作。

解决方案

先进入默认环境base，退出默认环境，再进入自定义环境openne。

[email protected] ~ % source activate
(base) [email protected] ~ % conda deactivate
[email protected] ~ % conda activate openne
(openne) [email protected]~ % 

在此基础上，再切换至另一个自定义环境 embedding，就不需要重新进入默认环境 base 了，退出当前环境 openne，直接用 conda activate embedding 即可。

(openne) [email protected] ~ % conda deactivate
[email protected] ~ % conda activate embedding
(embedding) [email protected] ~ %
