Sequelize CLI 找不到环境变量

Question

我正在尝试运行使用 Sequelize CLI 工具进行数据库迁移，但我运行遇到了一个问题，我的 ENV 变量没有被该工具处理。在 github 回购中，它说在 2.0.0 版中（我在 2.4.0 上）你可以像这样直接访问 config/config.js 中的 ENV 变量，process.env.DB_HOSTNAME，但我得到一个表示没有从变量传入任何值的错误

错误：

Unable to connect to database: SequelizeAccessDeniedError: ER_ACCESS_DENIED_ERROR: Access denied for user ''@'localhost' (using password: NO)

config.js:

module.exports = {
    "development": {
        "username": process.env.LOCAL_USERNAME,
        "password": process.env.LOCAL_PASSWORD,
        "database": process.env.LOCAL_DATABASE,
        "host": "127.0.0.1",
        "dialect": "mysql",
        "migrationStorageTableName": "sequelize_meta"
    },
}

.env:

LOCAL_DATABASE="db_name"
LOCAL_USERNAME="root"
LOCAL_PASSWORD="test"

您忘记要求 dotenv 模块：

require('dotenv').config();  // this line is important!
module.exports = {
"development": {
    "username": process.env.LOCAL_USERNAME,
    "password": process.env.LOCAL_PASSWORD,
    "database": process.env.LOCAL_DATABASE,
    "host": "127.0.0.1",
    "dialect": "mysql",
    "migrationStorageTableName": "sequelize_meta"
},
}
