위의 경로를 다음과 같이 bashrc 파일에 붙여넣은 다음 저장한다. 

(pyenv) founder@merrow:~/pyenv$ sudo nano ~/.bashrc

그리고 source .bashrc 를 통해 변경사항을 반영한 후, 다시 아나콘다를 활성화시킨다.

(pyenv) founder@merrow:~/pyenv$ source ~/.bashrc
founder@merrow:~/pyenv$ source activate pyenv
founder@merrow:~$ source activate pyenv
(pyenv) founder@merrow:~$
