原 因
The XSL stylesheets used by the Data Pump Metadata API were not loaded correctly into the Oracle dictionary table "sys.metastylesheet."   
It may be the cause that the stylesheets were not loaded at all in the database, or they were not converted to the database character set.   
Suppose if you convert your database character set using ALTER DATABASE statement then likely you will face this problem.   

解决方法
Note that never use ALTER DATABASE statement to migrate your characterset.   
1)Connect as sysdba. 

    SQL> sqlplus /nolog
    SQL> connect / as sysdba   
    Connected.   
2)Execute dbms_metadata_util.load_stylesheets to reload the stylesheets.   
    SQL> exec dbms_metadata_util.load_stylesheets;   
    PL/SQL procedure successfully completed.   
3)Exit and run the above query,   
    SQL>exit
