Modifying the migration file

When changing a column in Laravel,

① Install doctrine/dbal

② Add the following description to the migration file

$table->string('content',1000)->change()

and execute.

Error message

When I ran the command

php artisan migrate

I got the following error:

Laravel v6 is only compatible with doctrine/dbal 2, in order to use this feature you must require the package "doctrine/dbal:^2.6".

Solution

The error occurred because the doctrine/dbal package version did not match.

It seems that Laravel6 requires the previous version of doctrine/dbal.

So,

Conclusion

composer require "doctrine/dbal:^2.6"

This command will solve the issue!

Example that will cause problems by installing the latest version:

composer require doctrine/dbal

Summary

That's all.

See you!
