sou-bash: _get_comp_words_by_ref: 未找到命令

不管是kubectl 还是helm 出现的问题

sou-bash: _get_comp_words_by_ref: 未找到命令

解决：
1、下载

[root@localhost ~]# yum install bash-completion -y

2、执行bash_completion

[root@localhost ~]# source /usr/share/bash-completion/bash_completion 

3、
重新加载completion ( kubectl和helm)

[root@localhost ~]# source <(kubectl completion bash)
[root@localhost ~]# source <(helm  completion bash)

4、测试

[root@localhost ~]# helm 
completion  (generate autocompletion scripts for the specified shell)
create      (create a new chart with the given name)
dependency  (manage a chart's dependencies)
env         (helm client environment information)
get         (download extended information of a named release)
help        (Help about any command)
history     (fetch release history)

[root@localhost ~]# kubectl get
