Mysql 尝试复制用户时无法分析grant语句

我试图使用

mysqluserclone

复制一个用户，我得到以下信息：

ubuntu@****:~$ mysqluserclone --source=<rootuser>:<password>@<db_endpoint> --destination=<rootuser>:<password>@<db_endpoint> '<sourceuser>'@'%' '<destinationuser>'@'%' -vvv
WARNING: Using a password on the command line interface can be insecure.
# Source on <db_endpoint>: ... connected.
# Destination on <db_endpoint>: ... connected.
# Cloning 1 users...

ubuntu@****：~$mysqluserclone--source=：@--destination=：@''''''@'%'-vvv
