但是，当我运行“heroku run npm run migrate”时，我遇到了以下问题：

heroku run knex migrate:latest

knexfile.js

`const dotenv = require('dotenv')
dotenv.config()

module.exports = {
client: 'pg',
connection: process.env.DATABASE_URL,
ssl: { rejectUnauthorized: false }
};`

膝关节迁移：

`exports.up = function (knex) {
return Promise.all(
[knex.schema.createTable('posts', table => {
table.string('id', 36)
table.string('title', 50)
table.string('content')
}),
knex.schema.createTable('replies', table => {
table.string('id', 36)
table.string('title', 50)
table.string('postid', 36)
})]
)
};

exports.down = function (knex) {
knex.schem.dropTable('posts')
knex.schema.dropTable('replies')
};`

让我知道我是否应该以不同的方式呈现此信息，在我学习如何使用此平台时添加或删除文件。谢谢！

我最终创建了 knex 迁移，并且能够在 heroku 上验证我的数据库。

我确实必须制作一个“seed:live”脚本，该脚本使用 postgres 运行种子。前任： "scripts": {..."seed:live": "heroku pg:psql -f seeds/seed.posts.sql; heroku pg:psql -f seeds/seed.replies.sql"...}

验证数据库的种子：

heroku pg:psql -f seeds/seed.posts.sql; heroku pg:psql -f seeds/seed.replies.sql --> Connecting to postgresql-cubed-11974 INSERT 0 3 --> Connecting to postgresql-cubed-11974 INSERT 0 2

但现在它起作用了！
