我四处搜寻，只有这种解决方案对我有帮助:

I've searched around, and only this solution helped me:

mysql -u root -p

set global net_buffer_length=1000000; --Set network buffer length to a large byte number

set global max_allowed_packet=1000000000; --Set maximum allowed packet size to a large byte number

SET foreign_key_checks = 0; --Disable foreign key checking to avoid delays,errors and unwanted behaviour

source file.sql --Import your sql dump file

SET foreign_key_checks = 1; --Remember to enable foreign key checks when procedure is complete!
