在Heroku上运行Knex迁移时出现“'Error: Self-signed Certificate”

Question

更新#1

不幸的是，我找不到我使用postgrator解决这个问题时的截图。我最终选择了knex，转而尝试连接heroku。

然而，当我运行'heroku run npm run migrate‘时，我遇到了以下问题：

heroku run knex migrate:latest
Running knex migrate:latest on ⬢ stormy-hollows-73700... up, 
run.6282 (Free)

}

knexfile.js

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

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

knex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')
};`

让我知道如果我应该以不同的方式呈现此信息，添加或删除文件，因为我正在学习如何使用这个平台。谢谢!

我最终创建了一个knex迁移，并能够在heroku上验证我的数据库。

我确实需要编写一个"seed:live“脚本，使用postgres运行seed。例如："scripts": {..."seed:live": "heroku pg:psql -f seeds/seed.posts.sql; heroku pg:psql -f seeds/seed.replies.sql"...}

要验证数据库的种子设定，请执行以下操作：

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！
