【问题描述】：

当我运行 yarn knex migrate:make init 时，我收到此错误

Failed to resolve config file, knex cannot determine where to generate migrations

knexfile.js

require("dotenv").config();

module.exports = {
  development: {
    client: "pg",
    useNullAsDefault: true,
    debug: process.env.NODE_ENV === 'development',
    connection: {
      host: process.env.POSTGRES_DEV_HOST,
      port: process.env.POSTGRES_DEV_PORT,
      user: process.env.POSTGRES_DEV_USER,
      password: process.env.POSTGRES_DEV_PASSWORD,
      database: process.env.POSTGRES_DEV_DATABASE
    },
    migrations: {
      directory: "./migrations"
    },
    seeds: {
      directory: "./seeds"
    }
  }
};

数据库/index.js

const knexfile = require('./knexfile')
const debug = require('debug')
const knex = require('knex')
const util = require('util')

const log = debug('app:db')

const env = process.env.NODE_ENV
const config = knexfile[env]

log(`Connected to ${config.client} with parameters: ${util.inspect(config.connection, { colors: true })}`)

module.exports = knex(config)

有人建议我在全球范围内安装 Knex，运行 knex migrate:make init 并成功了。但我想知道它对生产有好处吗？

【问题讨论】：

knexfile.js 在哪里？ knexfile.js 和 package.json 是否位于同一级别？
不，这两个文件位于不同的文件夹中。因为我希望它们在不同的文件夹中
那么，您可能需要通过--knexfile 像这样yarn knex migrate:make init --knexfile=./config/knexfile.jsyarn knex migrate:make init --knexfile=./config/knexfile.js 来定义配置文件的位置
我尝试了类似的东西，yarn knex migrate:make init --knexfile --directory ./config/knexfile.js。这没有用。虽然我会试试这个。
knex cli 选项中没有--directory。

【解决方案1】：

感谢Mic Fung我得到了这个解决方案，

yarn knex migrate:make init  --knexfile=./config/knexfile.js

如果你们有不同的解决方案，请分享。

我全局安装了knex
