Similar prompts also appear when you use some other commands, such as mysqlhotcopy.
Searched for a good while and tried several times to find a simple way to solve the problem, as follows:

Vi/root/.bashrc
And at the bottom, add
Export Lc_all=c
or run directly
echo "Export Lc_all=c" >>/ROOT/.BASHRC
And then do it:
Source/root/.bashrc
All right.
