新人想请问下 neo4j导入csv文件报错的问题 之前导入过一次，后面想继续导入时就报错了 报错语句为

Import error: /Users/jianlinzeng/neo4j/data/databases/neo4j already contains data, cannot do import here Caused by:/Users/jianlinzeng/neo4j/data/databases/neo4j already contains data, cannot do import here java.lang.IllegalStateException: /Users/jianlinzeng/neo4j/data/databases/neo4j already contains data, cannot do import here at org.neo4j.internal.batchimport.store.BatchingNeoStores.assertDatabaseIsEmptyOrNonExistent(BatchingNeoStores.java:211) at org.neo4j.internal.batchimport.store.BatchingNeoStores.createNew(BatchingNeoStores.java:191) at org.neo4j.internal.batchimport.ParallelBatchImporter.doImport(ParallelBatchImporter.java:98) 导入语句为 bin/neo4j-admin import --nodes import/Person.csv, import/Phone.csv

求大佬执教
