Knex迁移不起作用,怎么回事？

Question

我似乎无法使用knex迁移数据库.在up命令中,它失败了.

knex.migrate.latest({}).finally(function () {
  knex.destroy()
})

我收到一个错误.

Possibly unhandled TypeError: undefined is not a function

我发誓昨天工作了.我尝试删除并重新创建数据库.没运气.怎么了？我怎样才能解决这个问题？

在knex来源中似乎没有任何明显的挖掘.

没关系,是愚蠢的.尝试在未设置的配置中使用环境变量.

var knex = require('knex')

var config = {
  client: 'pg',
  connection: process.env.DATABASE_URL,
}

module.exports = knex(config)

现在工作.
