gcloud ModuleNotFoundError: No module named 'CommandNotFound'

~$ gcloud
Traceback (most recent call last):
  File "/usr/lib/command-not-found", line 27, in <module>
    from CommandNotFound.util import crash_guard
ModuleNotFoundError: No module named 'CommandNotFound'

 

위와 같은 에러는 환경변수 경로를 지정하지 못해 발생하는 것인데, 

source '[path-to-my-home]/google-cloud-sdk/path.bash.inc'
source '[path-to-my-home]/google-cloud-sdk/completion.bash.inc'

를 .bashrc에 추가하여도 좋다.
