ORA-39006: internal error
ORA-39213: Metadata processing is not available
本以为是版本之间的问题，后来按如下解决方式，可以正常导入。
Cause: The Data Pump could not use the Metadata API. Typically, this is caused by the XSL stylesheets not being set up properly.
Action: Connect AS SYSDBA and execute dbms_metadata_util.load_stylesheets to reload the stylesheets.
