LC_IDENTIFICATION = "en_GB.UTF-8",
LC_NUMERIC = "en_GB.UTF-8",
LC_PAPER = "en_GB.UTF-8",
LANG = "en_US.UTF-8"
  are supported and installed on your system.
perl: warning: Falling back to a fallback locale ("en_US.UTF-8").
locale: Cannot set LC_ALL to default locale: No such file or directory

原因是在 ssh login 時，傳送過去的編碼資料不存在於遠端主機所導致

解決方法很簡單，把編碼的資料建立起來就可以了
