当我尝试使用 node_modules/.bin/sequelize db:migrate 迁移时遇到此错误

我认为mysql2包会导致这个错误

感谢您的帮助

【解决方案1】：

首先，请确保您的 config.json 不包含任何不带引号的值，例如本例中的密码：

{
 "my_env": {
    "username": "root",
    "password": 1234,
    "database": "my_db",
    "host"    : "localhost",
    "dialect" : "mysql"
  }
}

如果这不能解决您的问题，并且您有充分的理由相信它与 mysql2 软件包有关，请尝试将您的 sequelize 软件包降级到 v3，它使用 mysql 而不是 mysql2

【解决方案2】：

如果你使用命令“sequelize init”来初始化项目，那么你应该检查你的config.json。因为默认情况下“port”字段没有包括。同时，请确保您的 config.json 中不包含任何未引用的密码，如本例中的密码。

{
 "my_env": {
    "username": "root",
    "password": 1234,
    "database": "my_db",
    "host"    : "localhost",
    "dialect" : "mysql"
  }
}

【解决方案3】：

就我而言，我的 database.json 文件中有一个空对象：

{
  "dev": {
    "driver": "pg",
    "user": {"ENV": "DB_USER"},
    "password": {"ENV": "DB_PASS"},
    "host": {"ENV": "DB_HOST"},
    "database": {},              <-- THIS LINE
    "port": {"ENV": "DB_PORT"}
  }
}

该行："database": {}, 导致了问题。

“数据库”应该是一个字符串。
