About 1050 Table 'role_user' already exists

[ccb1900]

When I delete my old user migration and create a new user migration .
I got an error about"a foreign key constraint fails".
I modify my new user migration the same as old user migration,it works well.

that mean
Old:

2014_09_24_181007_create_users_table

->
New:

2016_09_24_181007_create_users_table

as you see ,the problem is that a foreign required that your packages migration must after my user migrations.
