Re installed MySQL choosing Legacy Authentication Method as shown in iamge attached SQL Authentication method
Database parameters in .env as follows
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=database_name DB_USERNAME=database_username DB_PASSWORD=database_password(if any)Database parameters in config/database.php
'mysql' => [ 'driver' => 'mysql', 'url' => env('DATABASE_URL'), 'host' => env('DB_HOST', '127.0.0.1'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'database_name'), 'username' => env('DB_USERNAME', 'database_username'), 'password' => env('DB_PASSWORD', 'database_password'), 'unix_socket' => env('DB_SOCKET', ''), 'charset' => 'utf8mb4', 'collation' => 'utf8mb4_unicode_ci', 'prefix' => '', 'prefix_indexes' => true, 'strict' => true, 'engine' => null, 'options' => extension_loaded('pdo_mysql') ? array_filter([ PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'), ]) : [], ],Run
php artisan migratefrom the projects terminal
重新安装 MySQL，选择 Legacy Authentication Method，如 iamge 附加的SQL Authentication method 所示
.env中的数据库参数如下
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=database_name DB_USERNAME=database_username DB_PASSWORD=database_password(if any)config/database.php 中的数据库参数
'mysql' => [ 'driver' => 'mysql', 'url' => env('DATABASE_URL'), 'host' => env('DB_HOST', '127.0.0.1'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'database_name'), 'username' => env('DB_USERNAME', 'database_username'), 'password' => env('DB_PASSWORD', 'database_password'), 'unix_socket' => env('DB_SOCKET', ''), 'charset' => 'utf8mb4', 'collation' => 'utf8mb4_unicode_ci', 'prefix' => '', 'prefix_indexes' => true, 'strict' => true, 'engine' => null, 'options' => extension_loaded('pdo_mysql') ? array_filter([ PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'), ]) : [], ],php artisan migrate从项目终端运行

By Providing DB_SOCKET in .env file this issue can be resolved like this :
通过在 .env 文件中提供 DB_SOCKET 这个问题可以这样解决：
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=my_db
DB_USERNAME=root
DB_PASSWORD=
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

This query solved my problem.
这个查询解决了我的问题。
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

Go to your .env file and make sure DB_CONNECTION=mysqland DB connections are correct.
转到您的 .env 文件并确保DB_CONNECTION=mysql数据库连接正确。
