php - 运行迁移时的“No such file or directory”或“No such host is known”

Question

我从名为migrations的Laravel 5.4数据库中删除了laravel表。当我运行php artisan migrate:install时，出现以下错误:

[Illuminate\Database\QueryException]
SQLSTATE[HY000] [2002] No such file or directory
(SQL: select * from information_schema.tables where table_schema = laravel
    and table_name = migrations)

我删除并重新创建了数据库。我还运行了 composer update。没运气。我可以在phpMyAdmin中运行命令并手动创建表。
有时，此问题也以类似的2002错误表现出来:

[Illuminate\Database\QueryException]
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.
(SQL: select * from information_schema.tables where table_schema = laravel
    and table_name = migrations and table_type = 'BASE TABLE')

[Illuminate\Database\QueryException]
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
(SQL: select * from information_schema.tables where table_schema = laravel
    and table_name = migrations and table_type = 'BASE TABLE')

Answer 1

如果您将localhost用作DATABASE_HOST文件中的.env，请将其更改为127.0.0.1，然后运行php artisan config:clear并现在再次尝试php artisan migrate:install。
