私は周りを検索しましたが、この解決策だけが役に立ちました：
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!
