How to enable shell command completion for gcloud?
提问by Kurt Peek
I'm trying to install the Google Cloud SDK on a Mac (following https://cloud.google.com/sdk/docs/quickstart-mac-os-x), using the install.shscript:
我正在尝试使用脚本在 Mac 上安装 Google Cloud SDK（遵循https://cloud.google.com/sdk/docs/quickstart-mac-os-x）install.sh：
~/Downloads$ ./google-cloud-sdk/install.sh
In the logged output, I see the following instructions:
在记录的输出中，我看到以下说明：
==> Source [/Users/kurtpeek/Downloads/google-cloud-sdk/completion.bash.inc] in your profile to enable shell command completion for gcloud.
==> Source [/Users/kurtpeek/Downloads/google-cloud-sdk/path.bash.inc] in your profile to add the Google Cloud SDK command line tools to your $PATH.
Indeed, I find that using the gsutilcommand still leads to a -bash: gsutil: command not founderror, so I still probably have to perform this step.
确实，我发现使用该gsutil命令仍然会导致-bash: gsutil: command not found错误，因此我可能仍然需要执行此步骤。
It is not entirely clear to me, however, what is meant by these instructions. I'm on a Mac and my bash profile is ~/.bash_profile. What lines would I have to add in order to make the command line completion work?
然而，我并不完全清楚这些说明的含义。我在 Mac 上，我的 bash 配置文件是~/.bash_profile. 我必须添加哪些行才能使命令行完成工作？
Update
更新
The first time I installed I did not use sudo. Reinstalling with sudo, I get an additional prompt whether to modify my bash profile, which upon accepting leads to the following lines added to my .bash_profile:
我第一次安装时没有使用sudo. 使用 重新安装sudo，我收到一个额外提示是否修改我的 bash 配置文件，在接受后会导致以下行添加到我的.bash_profile：
# The next line updates PATH for the Google Cloud SDK.
if [ -f '/Users/kurtpeek/Downloads/google-cloud-sdk/path.bash.inc' ]; then source '/Users/kurtpeek/Downloads/google-cloud-sdk/path.bash.inc'; fi
# The next line enables shell command completion for gcloud.
if [ -f '/Users/kurtpeek/Downloads/google-cloud-sdk/completion.bash.inc' ]; then source '/Users/kurtpeek/Downloads/google-cloud-sdk/completion.bash.inc'; fi
However, I still get gsutil: command not founderrors.
但是，我仍然遇到gsutil: command not found错误。

The trick was to run the install.shusing sudoas described in the update. After that I needed to restart the terminal (as described in the instructions) for the changes to take effect.
诀窍是按照更新中的描述运行install.shusing sudo。之后，我需要重新启动终端（如说明中所述）以使更改生效。
